`Bokeh <https://bokeh.pydata.org>`__ is a Python interactive visualization
|
|
library that targets modern web browsers for presentation. Its goal is to
|
|
provide elegant, concise construction of basic exploratory and advanced
|
|
custom graphics in the style of D3.js, but also deliver this capability with
|
|
high-performance interactivity over very large or streaming datasets. Bokeh
|
|
can help anyone who would like to quickly and easily create interactive
|
|
plots, dashboards, and data applications.
|
|
|
|

|
|
|
|
pip install bokeh==0.12.7
|
|
|
|
Usage
|
|
=====
|
|
|
|
To insert a Bokeh chart in a view proceed as follows:
|
|
|
|
#. Declare a text computed field like this::
|
|
|
|
bokeh_chart = fields.Text(
|
|
string='Bokeh Chart',
|
|
compute=_compute_bokeh_chart)
|
|
|
|
#. In its computed method do::
|
|
|
|
def _compute_bokeh_chart(self):
|
|
for rec in self:
|
|
# Design your bokeh figure:
|
|
p = figure()
|
|
line = p.line([0, 2], [1, 8], line_width=5)
|
|
# (...)
|
|
# Get the html components and convert them to string into the field.
|
|
script, div = components(p)
|
|
rec.bokeh_chart = '%s%s' % (div, script)
|
|
|
|
#. In the view, add something like this wherever you want to display your
|
|
bokeh chart::
|
|
|
|
<div>
|
|
<field name="bokeh_chart" widget="bokeh_chart" nolabel="1"/>
|
