I am currently doing where a need to update a ColumnDataSource in real-time using three sliders. I need to update the data for two reasons the first is to modify the glyph color according to the value of the slider and after that, i want to be able to display the points on a data table and download the data table.
So I use the function custumJS but it doesn’t work. I think the problem is from the command source.on_change(“value”) but I am not sure because I have some trouble using the callback .
I put an issue on StackOverflow :
