  10. `Bokeh <https://bokeh.pydata.org>`__ is a Python interactive visualization
  11. library that targets modern web browsers for presentation. Its goal is to
  12. provide elegant, concise construction of basic exploratory and advanced
  13. custom graphics in the style of D3.js, but also deliver this capability with
  14. high-performance interactivity over very large or streaming datasets. Bokeh
  15. can help anyone who would like to quickly and easily create interactive
  16. plots, dashboards, and data applications.
  17. If you want to see some samples of bokeh's capabilities follow this `link
  18. <https://bokeh.pydata.org/en/latest/docs/gallery.html>`_.

  23. Usage
  24. =====
  25. To insert a Bokeh chart in a view proceed as follows:
  26. #. Declare a text computed field like this::
  27. bokeh_chart = fields.Text(
  28. string='Bokeh Chart',
  29. compute=_compute_bokeh_chart)
  30. #. In its computed method do::
  31. def _compute_bokeh_chart(self):
  32. for rec in self:
  33. # Design your bokeh figure:
  34. p = figure()
  35. line = p.line([0, 2], [1, 8], line_width=5)
  36. # (...)
  37. # Get the html components and convert them to string into the field.
  38. script, div = components(p)
  39. rec.bokeh_chart = '%s%s' % (div, script)
  40. #. In the view, add something like this wherever you want to display your
  41. bokeh chart::
  42. <div>
  43. <field name="bokeh_chart" widget="bokeh_chart" nolabel="1"/>
