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',
|
|
)
|
|
|
|
#. 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>
