Why Highcharts for Python?
Highcharts <https://www.highcharts.com>
__ is the world's most popular, most powerful,
category-defining JavaScript data visualization library. If you are building a web or
mobile app/dashboard that will be visualizing data in some fashion, you should
absolutely take a look at the Highcharts suite of solutions. Take a peak at some
fantastic demo visualizations <https://www.highcharts.com/demo>
__.
As a suite of JavaScript libraries, Highcharts <https://www.highcharts.com>
__ is
written in JavaScript, and is used to configure and render data visualizations in a
web browser (or other JavaScript-executing) environment. As a set of JavaScript
libraries, its audience is JavaScript developers. But what about the broader ecosystem of
Python developers and data scientists?
Given Python's increasing adoption as the technology of choice for data science and for
the backends of leading enterprise-grade applications, Python is often the backend that
delivers data and content to the front-end...which then renders it using JavaScript and
HTML.
There are numerous Python frameworks (Django, Flask, Tornado, etc.) with specific
capabilities to simplify integration with Javascript frontend frameworks (React, Angular,
VueJS, etc.). But facilitating that with Highcharts has historically been very difficult.
Part of this difficulty is because the Highcharts JavaScript suite - while supporting JSON as a
serialization/deserialization format - leverages JavaScript object literals to expose the
full power and interactivity of its data visualizations. And while it's easy to serialize
JSON from Python, serializing and deserializing to/from JavaScript object literal notation
is much more complicated.
This means that Python developers looking to integrate with Highcharts typically had to
either invest a lot of effort, or were only able to leverage a small portion of Highcharts'
rich functionality.
So we wrote the Highcharts for Python Toolkit to bridge that gap.
Highcharts for Python provides Python object representation for all of the
JavaScript objects defined in the
Highcharts (JavaScript) API <https://api.highcharts.com/highcharts/>
__. It provides automatic
data validation, and exposes simple and standardized methods for serializing those Python
objects back-and-forth to JavaScript object literal notation.
Highcharts Gantt for Python provides support for
the Highcharts Gantt <https://www.highcharts.com/products/maps/>
__ extension, which is
designed to provide extensive capabilities optimized for project, time, and resource
allocation data visualization with robust interactivity. For ease of use, it also includes
the full functionality of
Highcharts Stock for Python <https://stock-docs.highchartspython.com/>
__ and
Highcharts Core for Python <https://core-docs.highchartspython.com/>
__.
Key Highcharts Gantt for Python Features
-
Clean and consistent API. No reliance on "hacky" code, dict
and JSON serialization, or impossible to maintain / copy-pasted "spaghetti code".
-
Comprehensive Highcharts support. Every single Highcharts chart type and every
single configuration option is supported in Highcharts Gantt for Python. This
includes:
- the over 70 data visualization types supported by
Highcharts Core <https://www.highcharts.com/product/highcharts/>
__, - the 50+ visualizations supported by
Highcharts Stock <https://www.highcharts.com/products/stock/>
__ - the multiple Gantt visualizations available in
Highcharts Gantt <https://www.highcharts.com/product/gantt/>
__
all with full support for the rich JavaScript formatter (JS callback functions)
capabilities that are often needed to get the most out of Highcharts' visualization and
interaction capabilities.
.. note::

Supported Visualizations <https://gantt-docs.highchartspython.com/en/latest/visualizations.html>
__
-
Simple JavaScript Code Generation. With one method call, produce production-ready
JavaScript code to render your interactive visualizations using Highcharts' rich
capabilities.
-
Easy Chart Download. With one method call, produce high-end static
visualizations that can be downloaded or shared as files with your audience. Produce
static charts using the Highsoft-provided Highcharts Export Server, or using your
own private export server as needed.
-
Integration with Asana, Monday.com, and Jira. Your project data likely lives in
a modern project management platform like Asana <https://www.asana.com/>
,
Monday.com <https://www.monday.com>
, or Atlassian JIRA <https://www.atlassian.com>
__.
You can easily pull data from those platforms into your Highcharts Gantt visualizations
using one method call.
-
Integration with Pandas and PySpark. With two lines of code, produce a high-end
interactive visualization of your Pandas or PySpark dataframe.
-
Consistent Code Style. For Python developers, switching between Pythonic code
conventions and JavaScript code conventions can be...annoying. So
Highcharts for Python applies Pythonic syntax with automatic conversion between
Pythonic snake_case
notation and JavaScript camelCase
styles.

Hello World, and Basic Usage
- Import Highcharts Gantt for Python
==========================================
.. code-block:: python
PRECISE-LOCATION PATTERN: BEST PRACTICE!
This method of importing Highcharts for Python objects yields the fastest
performance for the import statement. However, it is more verbose and requires
you to navigate the extensive Highcharts Core for Python API.
Import classes using precise module indications. For example:
from highcharts_core.chart import Chart
from highcharts_core.global_options.shared_options import SharedOptions
from highcharts_core.options import HighchartsOptions
from highcharts_core.options.plot_options.bar import BarOptions
from highcharts_core.options.series.bar import BarSeries
CATCH-ALL PATTERN
This method of importing Highcharts for Python classes has relatively slow
performance because it imports hundreds of different classes from across the entire
library. This performance impact may be acceptable to you in your use-case, but
do use at your own risk.
Import objects from the catch-all ".highcharts" module.
from highcharts_core import highcharts
You can now access specific classes without individual import statements.
highcharts.Chart
highcharts.SharedOptions
highcharts.HighchartsOptions
highcharts.BarOptions
highcharts.BarSeries
- Create Your Chart
================================
.. code-block:: python
# from a primitive array, using keyword arguments
my_chart = Chart(data = [[1, 23], [2, 34], [3, 45]],
series_type = 'line')
# from a primitive array, using the .from_array() method
my_chart = Chart.from_array([[1, 23], [2, 34], [3, 45]],
series_type = 'line')
# from a Numpy ndarray, using keyword arguments
my_chart = Chart(data = numpy_array, series_type = 'line')
# from a Numpy ndarray, using the .from_array() method
my_chart = Chart.from_array(data = numpy_array, series_type = 'line')
# from a JavaScript file
my_chart = Chart.from_js_literal('my_js_literal.js')
# from a JSON file
my_chart = Chart.from_json('my_json.json')
# from a Python dict
my_chart = Chart.from_dict(my_dict_obj)
# from a Pandas dataframe
my_chart = Chart.from_pandas(df)
# from a PySpark dataframe
my_chart = Chart.from_pyspark(df,
property_map = {
'x': 'transactionDate',
'y': 'invoiceAmt',
'id': 'id'
},
series_type = 'line')
# from a CSV
my_chart = Chart.from_csv('/some_file_location/filename.csv')
# from a HighchartsOptions configuration object
my_chart = Chart.from_options(my_options)
# from a Series configuration, using keyword arguments
my_chart = Chart(series = my_series)
# from a Series configuration, using .from_series()
my_chart = Chart.from_series(my_series)
3. Configure Global Settings (optional)
.. code-block:: python
# Import SharedOptions
from highcharts_core.global_options.shared_options import SharedOptions
# from a JavaScript file
my_global_settings = SharedOptions.from_js_literal('my_js_literal.js')
# from a JSON file
my_global_settings = SharedOptions.from_json('my_json.json')
# from a Python dict
my_global_settings = SharedOptions.from_dict(my_dict_obj)
# from a HighchartsOptions configuration object
my_global_settings = SharedOptions.from_options(my_options)
4. Configure Your Chart / Global Settings
.. code-block:: python
from highcharts_core.options.title import Title
from highcharts_core.options.credits import Credits
# EXAMPLE 1.
# Using dicts
my_chart.title = {
'align': 'center',
'floating': True,
'text': 'The Title for My Chart',
'use_html': False,
}
my_chart.credits = {
'enabled': True,
'href': 'https://www.highchartspython.com/',
'position': {
'align': 'center',
'vertical_align': 'bottom',
'x': 123,
'y': 456
},
'style': {
'color': '#cccccc',
'cursor': 'pointer',
'font_size': '9px'
},
'text': 'Chris Modzelewski'
}
# EXAMPLE 2.
# Using direct objects
from highcharts_core.options.title import Title
from highcharts_core.options.credits import Credits
my_title = Title(text = 'The Title for My Chart',
floating = True,
align = 'center')
my_chart.options.title = my_title
my_credits = Credits(text = 'Chris Modzelewski',
enabled = True,
href = 'https://www.highchartspython.com')
my_chart.options.credits = my_credits
5. Generate the JavaScript Code for Your Chart
Now having configured your chart in full, you can easily generate the JavaScript code
that will render the chart wherever it is you want it to go:
.. code-block:: python
# EXAMPLE 1.
# as a string
js_as_str = my_chart.to_js_literal()
# EXAMPLE 2.
# to a file (and as a string)
js_as_str = my_chart.to_js_literal(filename = 'my_target_file.js')
6. Generate the JavaScript Code for Your Global Settings (optional)
.. code-block:: python
# as a string
global_settings_js = my_global_settings.to_js_literal()
# to a file (and as a string)
global_settings_js = my_global_settings.to_js_literal('my_target_file.js')
7. Generate a Static Version of Your Chart
.. code-block:: python
# as in-memory bytes
my_image_bytes = my_chart.download_chart(format = 'png')
# to an image file (and as in-memory bytes)
my_image_bytes = my_chart.download_chart(filename = 'my_target_file.png',
format = 'png')
8. Render Your Chart in a Jupyter Notebook
.. code-block:: python
my_chart.display()
