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::

    <div>
        <field name="bokeh_chart" widget="bokeh_chart" nolabel="1"/>
    </div>


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::

    <div>
        <field name="bokeh_chart" widget="bokeh_chart_json
