This module add the possibility to insert Bokeh charts into Odoo standard views.

|Bokeh Chart inserted into an Odoo view|

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.

If you want to see some samples of bokeh's capabilities follow this link <https://bokeh.pydata.org/en/latest/docs/gallery.html>__.

Installation

You need to install the python bokeh library:

::

pip3 install bokeh==3.1.1

Usage

To insert a Bokeh chart in a view proceed as follows:

Using a Char field

• Declare a text computed field like this:

  ::

  bokeh_chart = fields.Text( string='Bokeh Chart', compute='_compute_bokeh_chart', )

• At the top of the module add the following imports:

  ::

  from bokeh.plotting import figure from bokeh.embed import components import json

• 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) # (...) # fill the record field with both markup and the script of a chart. script, div = components(p, wrap_script=False) rec.bokeh_chart = json.dumps({"div": div, "script": script})

• In the view, add something like this wherever you want to display your bokeh chart:

  ::

Using a Json field

• Declare a json computed field like this:

  ::

  bokeh_chart = fields.Json( string='Bokeh Chart', compute='_compute_bokeh_chart', )

• At the top of the module add the following imports:

  ::

  from bokeh.plotting import figure from bokeh.embed import components

• 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) # (...) # fill the record field with both markup and the script of a chart. script, div = components(p, wrap_script=False) rec.bokeh_chart = {"div": div, "script": script}

• In the view, add something like this wherever you want to display your bokeh chart:

  ::

Known issues / Roadmap

• On 17, we could remove the char field and only use the Json Field
