react-vis

See the live demo at http://uber.github.io/react-vis

Overview

A collection of react components to render common data visualization charts, such as line/area/bar charts, heat maps, scatteplots, pie and donut charts, tables with fixed headers and tree maps.

Some notable features:

• Simplicity. react-vis doesn't require any deep knowledge of data visualization libraries to start building your first visualizations.
• Flexibility. react-vis provides a set of basic building blocks for different charts. For instance, separate X and Y axis components. This provides a high level of control of chart layout for applications that need it.
• Ease of use. The library provides a set of defaults which can be overriden by the custom user's settings.
• Integration with React. react-vis supports the React's lifecycle and doesn't create unnecessary nodes.

Usage

Install react-vis via npm.

npm install react-vis

Include the CSS from ./node_modules/react-vis/main in your HTML page or via SASS:

@import "./node_modules/react-vis/main";

Import the necessary components from the library…

import {XYPlot, XAxis, YAxis, HorizontalGridLines, LineSeries} from 'react-vis';

… and add the following code to your render function:

<XYPlot
  width={300}
  height={300}>
  <HorizontalGridLines />
  <LineSeries
    data={[
      {x: 1, y: 10},
      {x: 2, y: 5},
      {x: 3, y: 15}
    ]}/>
  <XAxis />
  <YAxis />
</XYPlot>

More information

Take a look at the folder with examples or check out some docs:

• Common concepts:
  • Scales and Data about how the attributes can be adjusted.
  • Animations about how to tweak animations in the library.
• Components:
  • XYPlot about orthogonal charts.
  • RadialChart about radial charts.
  • Table about table.
  • Treemap about making tree maps.
  • Legends about the legends.

Development

To develop on this component, install the dependencies and then build and watch the static files:

npm install && npm run watch

Once complete, you can view the component's example in your browser (will open automatically). Any changes you make to the example code will run the compiler to build the files again.

To lint your code, run the tests, and create code coverage reports:

npm test

Change log

0.6.4

• Bugfix: Fixed the issue with numeric titles in legends (#154).

0.6.3

• Bugfix: fix the broken event listeners for radial charts (#150);
• Bugfix: compatibility fix: do not treat null and undefined in scale props as existing values (#149).

0.6.2

• Feature: added a new tickLabelAngle property that rotates the tick label (see the documentation for details).
• Improvement: added a little bit of examples for the axes.
• Bugfix: fixed misplaced axis title when orientation is set to 'top' or 'right' (#146).

0.6.1

• Bugfix: axis is misplaced when orientation is set to 'right'(#143).

0.6

TL;DR

New legends (sic!), new animations, faster rendering of components, no d3 in actual rendering process, new examples and more.

Breaking changes

• animation property works differently: duration is removed in favor of stiffness, damping and precision. Please refer to the documentation for the latest changes.
• undefined and null values of important scale-related attributes for domains and ranges are now treated as real values (and not ignored anymore).

Non-breaking changes

• Feature: added the first version of legends (discrete and continuous color legends, continuous size legend). Please refer to the docs for legends for more details.
• Improvement: got rid of assigning properties with d3 after rendering, currently all attributes and event listeners are attached using React (and it is faster).
• Improvement: eliminated the use of d3-selection and d3-transition modules and made the source code smaller.
• Improvement: added some structure into the examples and simplified their source code (check them out).
• Bugfix: fixed crashing on animation (#114).
• Improvement: onNearestX event now returns the index of the selected data point as an attribute (more details here)
• Bugfix: added the donut chart to the list of examples (#83).
• Bugfix: fixed failing bar charts when the number of segments was changed (#55).

0.5

TL;DR

Upgraded to modular d3, compiled code became smaller, changed the API for axes and grids, fixed several bugs.

Breaking changes

• d3-axis is no longer used, the rendering of axes and grids is made by react (and works faster).
• The API of axes (XAxis and YAxis) was significantly changed:
  • the API of axes is now (almost) compatible to the API of 'd3-axis'.
  • labelFormat and labelValues attributes for the axes are removed: similar results can be done achieved when tickFormat and tickValues attributes are used (see the the updated documentation for axes for more details).
  • tickFormat function is now gets only one (value) argument instead of two (value and index).
• The API of grids (VerticalGridLines and HorizontalGridLines) was significantly changed: it partially replicates the API of the axes. Please refer to the updated documentation for more detail.

Non-breaking changes

• Bugfix: margin for the radial and ortogonal chart is now able to receive partial objects (e. g.<XYPlot margin={{left: 20}}> instead of margins for each side) and numbers (e.g. <XYPlot margin={20}>)
• Bugfix: makeVisFlexible doesn't fail anymore (see #118).
• Minor bugfixes and improvements.
