I am expecting to get a simple line bokeh plot returned by Flask, but what I get when I browse to localhost:5002/simpleline is this:
('', ' ')
I have two files. The Python file:
from bokeh.plotting import figure, show, output_file
from bokeh.embed import components
from flask import Flask, render_template
app=Flask(__name__)
@app.route('/simpleline/')
def simpleLine():
fig=figure(title="Sensor data")
fig.line([1,2,3,4],[2,4,6,8])
div=components(fig)
return render_template('simpleline.html',div=div)
show(fig)
if __name__ == "__main__":
app.run(debug=True,port=5002)
And the HTML template:
<!doctype html>
<html>
<head>
<title>Figure examples</title>
<link rel="stylesheet" href="http://cdn.bokeh.org/bokeh-0.7.1.min.css" type="text/css" />
<script type="text/javascript"src="http://cdn.bokeh.org/bokeh-0.7.1.min.js"></script>
</head>
<body>
<div class='bokeh'>
{{ div|safe }}
</div>
</body>
</html>
I am sure I am missing something essential here.
After mn's answer, it was found out that components() produces two elements, a Javascript string, and an html div. So, I updated my scripts as follows, but this time the web page shows as blank.
from bokeh.plotting import figure, show, output_file
from bokeh.embed import components
from flask import Flask, render_template
app=Flask(__name__)
@app.route('/simpleline/')
def simpleLine():
fig=figure(title="Sensor data")
fig.line([1,2,3,4],[2,4,6,8])
global script
global div
script,div=components(fig)
return render_template('simpleline.html',div=div,script=script)
output_file("simpleline.html")
show(fig)
fig=figure(title="Sensor data")
fig.line([1,2,3,4],[2,4,6,8])
script,div=components(fig)
if __name__ == "__main__":
app.run(debug=True,port=5002)
And the HTML template:
<!doctype html>
<html>
<head>
<title>Figure examples</title>
<link rel="stylesheet" href="http://cdn.bokeh.org/bokeh-0.9.0.min.css" type="text/css" />
<script type="text/javascript" src="http://cdn.bokeh.org/bokeh-0.9.0.min.js"></script>
{{ script|safe }}
</head>
<body>
<div class='bokeh'>
{{ div|safe }}
</div>
</body>
</html>
I tried all bokeh-0.7.1.min.js, 0.9, and 0.10, but I still got the same blank page.

components() returns (script, div) tuple with <script> that contains the data for your plot and an accompanying <div> tag that the plot view is loaded into:

script, div = components(fig)
return render_template('simpleline.html',div=div, script=script)
