QUESTION
Is it possible to use js_on_change
with bokeh
to dynamically update text that is placed next to a plot?
For example, using this code snippet from a different question
...ANSWER
Answered 2021-Mar-23 at 12:25You can Use a Text Widget like PreText
, place it on the right side of the plot e.g via layout
and update the .text
property of that widget in your JSCallback. Make sure you use the .toString()
methode to assign the value.
QUESTION
I'm trying to have a DataTable which will run a callback when the user press on a certain row. The call back need to have the value of the first column (for the selected row).
Tried few things but non of them worked:
...ANSWER
Answered 2020-May-04 at 18:16Your code is still incomplete: there are some imports of non-existing modules and the table is nowhere to be found.
However, those seemed to be easy to fix. The main issue with your code is that you're writing the JavaScript code for CustomJS
as if it was Python code.
Here's a working version of your code:
QUESTION
I've used previous posts here and here to try and run code whereby I can select a row in a DataTable in Bokeh, and get the row number. However I'm finding that using that code, once I get past row 6 or 7 the row number generated is wrong - for example I could be clicking on row 17 and it'll say it's row 6. How do I resolve this issue?
Note for the code in this post, the error only occurs once I increase the range in the 'source' ColumnDataSource from 10 to 20.
...ANSWER
Answered 2019-May-24 at 13:22My callback code did not work with tables that have scrollbars. Since then I updated it to something a bit more robust (but it works only for the 1st table widget in the document)
QUESTION
I am trying to update a data table automatically when I use box select on a Bokeh scatter plot. The table should display all the elements which are in the selected box.
This is for Bokeh version 1.0.4. Python 3.5 I've tried several methods to do this, but haven't got it to work.

Answered 2019-Apr-26 at 07:58If i understand you correctly I think I had the same problem (see this post).
The solution might be this one as provided by @Tony:
QUESTION
I have modified this example. What I want- eventually- is a way to get the datapoints selected in a graph and modifiy them in the python code. Thus I added a function here that should return the values from the second graph (thats what the button is for). However, if I select the points, they are plotted correctly, but the data source is not changed (the button click provides {'X':[],'Y':[]}. How do I write back from JS to the python bokeh data source? Isn't the s2.change.emit() or a s2.trigger('change') supposed to do this? I also tried the latter but its not working.
...ANSWER
Answered 2019-Apr-17 at 22:20This code will display the updated source data from the second plot when the button is clicked. Run it with: bokeh serve --show app.py
QUESTION
Question related to: Bokeh linking/ brushing based on column instead of row indices / index
I would like to use a selection tool for multiple selection instead of the "tap". For this I'm using the example shown customjs-for-selections. Unfortunately I seem to get stuck in a loop of changes using source.selected.indices='new selection'
.
Any suggestions how to update selection without triggering js_on_change
?
ANSWER
Answered 2019-Mar-18 at 20:33The callback from previous example still does the job when TapTool is replaced with the BoxSelectTool (tested on Bokeh v1.0.4):
QUESTION
I'm confused because I don't return state here, only action.payload (code snippet):
...ANSWER
Answered 2017-Jul-06 at 16:49Yes, that reducer is absolutely fine conceptually. That simply means that you want to replace whatever the existing state was with the contents of action.payload
. Here's a similar example to illustrate the principle:
