Visdom aims to facilitate visualization of (remote) data with an emphasis on supporting scientific experimentation.
Broadcast visualizations of plots, images, and text for yourself and your collaborators.
Organize your visualization space programmatically or through the UI to create dashboards for live data, inspect results of experiments, or debug experimental code.
Visdom has a simple set of features that can be composed for various use-cases.
The UI begins as a blank slate – you can populate it with plots, images, and text. These appear in windows that you can drag, drop, resize, and destroy. The windows live in envs and the state of envs is stored across sessions. You can download the content of windows – including your plots in svg.
Tip: You can use the zoom of your browser to adjust the scale of the UI.
The python Visdom implementation supports callbacks on a window. The demo shows an example of this in the form of an editable text pad. The functionality of these callbacks allows the Visdom object to receive and react to events that happen in the frontend.
You can subscribe a window to events by adding a function to the event handlers dict for the window id you want to subscribe by calling viz.register_event_handler(handler, win_id) with your handler and the window id. Multiple handlers can be registered to the same window. You can remove all event handlers from a window using viz.clear_event_handlers(win_id). When an event occurs to that window, your callbacks will be called on a dict containing:
event_type: one of the below event typespane_data: all of the stored contents for that window including layout and content.eid: the current environment idtarget: the window id the event is called onAdditional parameters are defined below.
Right now the following callback events are supported:
Close - Triggers when a window is closed. Returns a dict with only the aforementioned fields.KeyPress - Triggers when a key is pressed. Contains additional parameters:
key - A string representation of the key pressed (applying state modifiers such as SHIFT)key_code - The javascript event keycode for the pressed key (no modifiers)PropertyUpdate - Triggers when a property is updated in Property pane
propertyId - Position in properties listvalue - New property valueClick - Triggers when Image pane is clicked on, has a parameter:
image_coord - dictionary with the fields x and y for the click coordinates in the coordinate frame of the possibly zoomed/panned image (not the enclosing pane).
You can partition your visualization space with envs. By default, every user will have an env called main. New envs can be created in the UI or programmatically. The state of envs is chronically saved. Environments are able to keep entirely different pools of plots.
You can access a specific env via url: http://localhost.com:8097/env/main. If your server is hosted, you can share this url so others can see your visualizations too.
Environments are automatically hierarchically organized by the first _.
From the main page it is possible to toggle between different environments using the environment selector. Selecting a new environment will query the server for the plots that exist in that environment. The environment selector allows for searching and filtering for the new enironment.
From the main page it is possible to compare different environments using the environment selector. Selecting multiple environments in the check box will query the server for the plots with the same titles in all environments and plot them in a single plot. An additional compare legend pane is created with a number corresponding to each selected environment. Individual plots are updated with legends corresponding to "x_name" where x is a number corresponding with the compare legend pane and name is the original name in the legend.
Note: The compare envs view is not robust to high throughput data, as the server is responsible for generating the compared content. Do not compare an environment that is receiving a high quantity of updates on any plot, as every update will request regenerating the comparison. If you need to compare two plots that are receiving high quantities of data, have them share the same window on a singular env.
You can use the eraser button to remove all of the current contents of an environment. This closes the plot windows for that environment but keeps the empty environment for new plots.
Pressing the folder icon opens a dialog that allows you to fork or force save the current environment, or delete any of your existing environments. Use of this feature is fully described in the State section.
Env Files: Your envs are loaded upon request by the user, by default from
$HOME/.visdom/. Custom paths can be passed as a cmd-line argument. Envs are removed by using the delete button or by deleting the corresponding.jsonfile from the env dir. In case you want the server to pre-load all files into cache, use the flag-eager_data_loading.
Once you've created a few visualizations, state is maintained. The server automatically caches your visualizations -- if you reload the page, your visualizations reappear.
Save: You can manually do so with the save button. This will serialize the env's state (to disk, in JSON), including window positions. You can save an env programmatically.
This is helpful for more sophisticated visualizations in which configuration is meaningful, e.g. a data-rich demo, a model training dashboard, or systematic experimentation. This also makes them easy to share and reuse.
Fork: If you enter a new env name, saving will create a new env -- effectively forking the previous env.
Tip: Fork an environment before you begin to make edits to ensure that your changes are saved seperately.
You can use the filter to dynamically sift through windows present in an env -- just provide a regular expression with which to match titles of window you want to show. This can be helpful in use cases involving an env with many windows e.g. when systematically checking experimental results.
Note: If you have saved your current view, the view will be restored after clearing the filter.
It is possible to manage the views simply by dragging the tops of windows around, however additional features exist to keep views organized and save common views. View management can be useful for saving and switching between multiple common organizations of your windows.
Using the folder icon, a dialog window opens where views can be forked in the same way that envs can be. Saving a view will retain the position and sizes of all of the windows in a given environment. Views are saved in $HOME/.visdom/view/layouts.json in the visdom filepath.
Note: Saved views are static, and editing a saved view copies that view over to the
currentview where editing can occur.
Using the repack icon (9 boxes), visdom will attempt to pack your windows in a way that they best fit while retaining row/column ordering.
Note: Due to the reliance on row/column ordering and
ReactGridLayoutthe final layout might be slightly different than what might be expected. We're working on improving that experience or providing alternatives that give more fine-tuned control.
Using the view dropdown it is possible to select previously saved views, restoring the locations and sizes of all of the windows within the current environment to the places they were when that view was saved last.
Python and web clients come bundled with the python server.
Install from pip
> pip install visdom
Install from source
> pip install git+https://github.com/fossasia/visdom
Start the server (probably in a screen or tmux) from the command line:
> visdom
Visdom now can be accessed by going to http://localhost:8097 in your browser, or your own host address if specified.
The
visdomcommand is equivalent to runningpython -m visdom.server.
If the above does not work, try using an SSH tunnel to your server by adding the following line to your local
~/.ssh/config:LocalForward 127.0.0.1:8097 127.0.0.1:8097.
The following options can be provided to the server:
-port : The port to run the server on.-hostname : The hostname to run the server on.-base_url : The base server url (default = /).-env_path : The path to the serialized session to reload.-logging_level : Logging level (default = INFO). Accepts both standard text and numeric logging values.-readonly : Flag to start server in readonly mode.-enable_login : Flag to setup authentication for the sever, requiring a username and password to login.-force_new_cookie : Flag to reset the secure cookie used by the server, invalidating current login cookies.
Requires -enable_login.-bind_local : Flag to make the server accessible only from localhost.-eager_data_loading : By default visdom loads environments lazily upon user request. Setting this flag lets visdom pre-fetch all environments upon startup.When -enable_login flag is provided, the server asks user to input credentials using terminal prompt. Alternatively,
you can setup VISDOM_USE_ENV_CREDENTIALS env variable, and then provide your username and password via
VISDOM_USERNAME and VISDOM_PASSWORD env variables without manually interacting with the terminal. This setup
is useful in case if you would like to launch visdom server from bash script, or from Jupyter notebook.
VISDOM_USERNAME=username
VISDOM_PASSWORD=password
VISDOM_USE_ENV_CREDENTIALS=1 visdom -enable_login
You can also use VISDOM_COOKIE variable to provide cookies value if the cookie file wasn't generated, or the
flag -force_new_cookie was set.

For a quick introduction into the capabilities of visdom, have a look at the example directory, or read the details below.
The python visdom client takes a few options:
server: the hostname of your visdom server (default: 'http://localhost')port: the port for your visdom server (default: 8097)base_url: the base visdom server url (default: /)env: Default environment to plot to when no env is provided (default: main)raise_exceptions: Raise exceptions upon failure rather than printing them (default: True (soon))log_to_filename: If not none, log all plotting and updating events to the given file (append mode) so that they can be replayed later using replay_log (default: None)use_incoming_socket: enable use of the socket for receiving events from the web client, allowing user to register callbacks (default: True)http_proxy_host: Deprecated. Use Proxies argument for complete proxy support.http_proxy_port: Deprecated. Use Proxies argument for complete proxy support.username: username to use for authentication, if server started with -enable_login (default: None)password: password to use for authentication, if server started with -enable_login (default: None)proxies: Dictionary mapping protocol to the URL of the proxy (e.g. {http: foo.bar:3128}) to be used on each Request. (default: None)offline: Flag to run visdom in offline mode, where all requests are logged to file rather than to the server. Requires log_to_filename is set. In offline mode, all visdom commands that don't create or update plots will simply return True. (default: False)Other options are either currently unused (endpoint, ipv6) or used for internal functionality.
Visdom offers the following basic visualization functions:
vis.image : imagevis.images : list of imagesvis.text : arbitrary HTMLvis.properties : properties gridvis.audio : audiovis.video : videosvis.svg : SVG objectvis.matplot : matplotlib plotvis.save : serialize state server-sideWe have wrapped several common plot types to make creating basic visualizations easily. These visualizations are powered by Plotly.
The following API is currently supported:
vis.scatter : 2D or 3D scatter plotsvis.line : line plotsvis.stem : stem plotsvis.heatmap : heatmap plotsvis.bar : bar graphsvis.histogram : histogramsvis.boxplot : boxplotsvis.surf : surface plotsvis.contour : contour plotsvis.quiver : quiver plotsvis.mesh : mesh plotsvis.dual_axis_lines : double y axis line plotsNote that the server API adheres to the Plotly convention of data and layout objects, such that you can produce your own arbitrary Plotly visualizations:
import visdom
vis = visdom.Visdom()
trace = dict(x=[1, 2, 3], y=[4, 5, 6], mode="markers+lines", type='custom',
marker={'color': 'red', 'symbol': 104, 'size': "10"},
text=["one", "two", "three"], name='1st Trace')
layout = dict(title="First Plot", xaxis={'title': 'x1'}, yaxis={'title': 'x2'})
vis._send({'data': [trace], 'layout': layout, 'win': 'mywin'})
vis.close : close a window by idvis.delete_env : delete an environment by env_idvis.win_exists : check if a window already exists by idvis.get_env_list : get a list of all of the environments on your servervis.win_hash: get md5 hash of window's contentsvis.get_window_data: get current data for a windowvis.check_connection: check if the server is connectedvis.replay_log: replay the actions from the provided log file
This function draws an img. It takes as input an CxHxW tensor img
that contains the image.
The following opts are supported:
jpgquality: JPG quality (number 0-100). If defined image will be saved as JPG to reduce file size. If not defined image will be saved as PNG.caption: Caption for the imagestore_history: Keep all images stored to the same window and attach a slider to the bottom that will let you select the image to view. You must always provide this opt when sending new images to an image with history.Note You can use alt on an image pane to view the x/y coordinates of the cursor. You can also ctrl-scroll to zoom, alt scroll to pan vertically, and alt-shift scroll to pan horizontally. Double click inside the pane to restore the image to default.
This function draws a list of images. It takes an input B x C x H x W tensor or a list of images all of the same size. It makes a grid of images of size (B / nrow, nrow).
The following arguments and opts are supported:
nrow: Number of images in a rowpadding: Padding around the image, equal padding around all 4 sidesopts.jpgquality: JPG quality (number 0-100). If defined image will be saved as JPG to reduce file size. If not defined image will be saved as PNG.opts.caption: Caption for the imageThis function prints text in a box. You can use this to embed arbitrary HTML.
It takes as input a text string.
No specific opts are currently supported.
This function shows editable properties in a pane. Properties are expected to be a List of Dicts e.g.:
properties = [
{'type': 'text', 'name': 'Text input', 'value': 'initial'},
{'type': 'number', 'name': 'Number input', 'value': '12'},
{'type': 'button', 'name': 'Button', 'value': 'Start'},
{'type': 'checkbox', 'name': 'Checkbox', 'value': True},
{'type': 'select', 'name': 'Select', 'value': 1, 'values': ['Red', 'Green', 'Blue']},
]
Supported types:
value: id of selected value (zero based)values: list of possible valuesCallback are called on property value update:
event_type: "PropertyUpdate"propertyId: position in the properties listvalue: new valueNo specific opts are currently supported.
This function plays audio. It takes as input the filename of the audio
file or an N tensor containing the waveform (use an Nx2 matrix for stereo
audio). The function does not support any plot-specific opts.
The following opts are supported:
opts.sample_frequency: sample frequency (integer > 0; default = 44100)Known issue: Visdom uses scipy to convert tensor inputs to wave files. Some versions of Chrome are known not to play these wave files (Firefox and Safari work fine).
This function plays a video. It takes as input the filename of the video
videofile or a LxHxWxC-sized
tensor containing all the frames of the video as input. The
function does not support any plot-specific opts.
The following opts are supported:
opts.fps: FPS for the video (integer > 0; default = 25)Note: Using tensor input requires that ffmpeg is installed and working.
Your ability to play video may depend on the browser you use: your browser has
to support the Theano codec in an OGG container (Chrome supports this).
This function draws an SVG object. It takes as input a SVG string svgstr or
the name of an SVG file svgfile. The function does not support any specific
opts.
This function draws a Matplotlib plot. The function supports
one plot-specific option: resizable.
Note When set to
Truethe plot is resized with the pane. You needbeautifulsoup4andlxmlpackages installed to use this option.
Note:
matplotis not rendered using the same backend as plotly plots, and is somewhat less efficient. Using too many matplot windows may degrade visdom performance.
This function draws a Plotly Figure object. It does not explicitly take options as it assumes you have already explicitly configured the figure's layout.
Note You must have the
plotlyPython package installed to use this function. It can typically be installed by runningpip install plotly.
This function visualizes a collection of features using the Barnes-Hut t-SNE algorithm.
The function accepts the following arguments:
features: a list of tensorslabels: a list of corresponding labels for the tensors provided for featuresdata_getter=fn: (optional) a function that takes as a parameter an index into the features array and returns a summary representation of the tensor. If this is set, data_type must also be set.data_type=str: (optional) currently the only acceptable value here is "html"We currently assume that there are no more than 10 unique labels, in the future we hope to provide a colormap in opts for other cases.
From the UI you can also draw a lasso around a subset of features. This will rerun the t-SNE visualization on the selected subset.
This function saves the envs that are alive on the visdom server. It takes input a list of env ids to be saved.
Further details on the wrapped plotting functions are given below.
The exact inputs into the plotting functions vary, although most of them take as input a tensor X than contains the data and an (optional) tensor Y that contains optional data variables (such as labels or timestamps). All plotting functions take as input an optional win that can be used to plot into a specific window; each plotting function also returns the win of the window it plotted in. One can also specify the env to which the visualization should be added.
This function draws a 2D or 3D scatter plot. It takes as input an Nx2 or
Nx3 tensor X that specifies the locations of the N points in the
scatter plot. An optional N tensor Y containing discrete labels that
range between 1 and K can be specified as well -- the labels will be
reflected in the colors of the markers.
update can be used to efficiently update the data of an existing plot. Use 'append' to append data, 'replace' to use new data, or 'remove' to remove the trace specified by name.
Using update='append' will create a plot if it doesn't exist and append to the existing plot otherwise.
If updating a single trace, use name to specify the name of the trace to be updated. Update data that is all NaN is ignored (can be used for masking update).
The following opts are supported:
opts.markersymbol : marker symbol (string; default = 'dot')opts.markersize : marker size (number; default = '10')opts.markercolor : color per marker.

For example traceopts = {'plotly': {'myTrace': {'mode': 'markers'}}}.opts.webgl : use WebGL for plotting (boolean; default = false). It is faster if a plot contains too many points. Use sparingly as browsers won't allow more than a couple of WebGL contexts on a single page.opts.markercolor is a Tensor with Integer values. The tensor can be of size N or N x 3 or K or K x 3.
N: Single intensity value per data point. 0 = black, 255 = redN x 3: Red, Green and Blue intensities per data point. 0,0,0 = black, 255,255,255 = whiteK and K x 3: Instead of having a unique color per data point, the same color is shared for all points of a particular label.This function draws a sunburst chart. It takes two inputs: parents and labels array.
values from parents array is used as parents object, like it define above which sector
should the this sector shown. values from labels array is used to define sector's label
or you can say name. keep in mind that lenght of array parents and labels should be
equal. There is a third array that you can pass to which is value, it is use to show
a value on hovering over a sector, it is optional argument, but if you are passing it then
keep in mind lenght of values should be equal to parents or labels.
Following opts are currently supported:
opts.font_size : define font size of label (int)opts.font_color : define font color of label (string)opts.opacity : define opacity of chart (float)opts.line_width : define distance between two sectors and sector to its parents (int)This function draws a line plot. It takes as input an N or NxM tensor
Y that specifies the values of the M lines (that connect N points)
to plot. It also takes an optional X tensor that specifies the
corresponding x-axis values; X can be an N tensor (in which case all
lines will share the same x-axis values) or have the same size as Y.
update can be used to efficiently update the data of an existing plot. Use 'append' to append data, 'replace' to use new data, or 'remove' to remove the trace specified by name. If updating a single trace, use name to specify the name of the trace to be updated. Update data that is all NaN is ignored (can be used for masking update).

specifies the value at each location in the heatmap.
update can be used to efficiently update the data of an existing plot. Use 'appendRow' to append data row-wise, 'appendColumn' to append data column-wise, 'prependRow' to prepend data row-wise, 'prependColumn' to prepend data column-wise, 'replace' to use new data, or 'remove' to remove the plot specified by win.
