I'm using a Bokeh Select widget,
I worked off of this example: http://demo.bokehplots.com/apps/movies
full source code: https://github.com/bokeh/bokeh/tree/mast...app/movies
1) Use the description.html file from the movies app if you try running the code below. It should be placed in the same dir as the script.
https://github.com/bokeh/bokeh/blob/mast...ption.html
2) you also need to create a dir in the same location as the script. place at least one file in there. the name or names of the files in the data dir will appear on the drop down.
from bokeh.models.widgets import Select
which is essentially a dropdown on a web page. eg: http://v4-alpha.getbootstrap.com/components/dropdowns/. I'm trying to figure out how to update the values after bokeh server has been initialized. for example. when the server is started, the Select widget has the values, [foo, bar]
. I update that list with an myList.append('baz') so that the list now contains ['foo','bar','baz']
but the widget doesn't show the new value. If the process below seems to complicated, I can create a github project for it.I worked off of this example: http://demo.bokehplots.com/apps/movies
