Colormaps
=========

Usage 
-----

The :code:`easychart` package comes pre-loaded with the 83 colormaps available in `matplotlib <https://matplotlib.org/stable/users/explain/colors/colormaps.html>`_. Each of these can be assigned by name to the :code:`chart.cAxis` to convert the colormap to the `chart.colorAxis.stops <https://api.highcharts.com/highcharts/colorAxis.stops>`_ of the relevant chart. 

.. note:: 

    Colormap names are case-insensitive

.. literalinclude:: /_misc/examples/chart-61.py

.. raw:: html 

    <div class="chart-container" style="min-height:400px" data-filename="../_static/charts/chart-61.json?v=1"></div>


Each colormap can be reversed by appending :code:`.reversed` to its name.

.. literalinclude:: /_misc/examples/chart-62.py

.. raw:: html 

    <div class="chart-container" style="min-height:400px" data-filename="../_static/charts/chart-62.json?v=1"></div>

Each colormap can also be mirrored by appending :code:`.symmetric` to its name.

.. literalinclude:: /_misc/examples/chart-63.py

.. raw:: html 

    <div class="chart-container" style="min-height:400px" data-filename="../_static/charts/chart-63.json?v=1"></div>

And :code:`.reversed` and :code:`.symmetric` can be used jointly.

.. literalinclude:: /_misc/examples/chart-64.py

.. raw:: html 

    <div class="chart-container" style="min-height:400px" data-filename="../_static/charts/chart-64.json?v=1"></div>
