how to embed standalone bokeh graphs into django templates
I want to display graphs offered by the bokeh library in my web application via django framework but I don't want to use the bokeh-server executable because it's not the good way. so is that possible? if yes how to do that?
Answer
Using the Embedding Bokeh Plots documentation example as suggested by Fabio Pliger, one can do this in Django:
in the views.py file, we put:
from django.shortcuts import render
from bokeh.plotting import figure
from bokeh.resources import CDN
from bokeh.embed import components
def simple_chart(request):
plot = figure()
plot.circle([1,2], [3,4])
script, div = components(plot, CDN)
return render(request, "simple_chart.html", {"the_script": script, "the_div": div})
in the urls.py file we can put :
from myapp.views import simple_chart
...
...
...
url(r'^simple_chart/$', simple_chart, name="simple_chart"),
...
...
in the template file simple_chart.html we'll have :
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Experiment with Bokeh</title>
<script src="http://cdn.bokeh.org/bokeh/release/bokeh-0.8.1.min.js"></script>
<link rel="stylesheet" href="http://cdn.bokeh.org/bokeh/release/bokeh-0.8.1.min.css">
</head>
<body>
{{ the_div|safe }}
{{ the_script|safe }}
</body>
</html>
And it works.
