Trying a simple script to plot line charts. Y-axis is integer, X-axis is a time.Multiple lines could be displayed on chart at the same time. I can hide a line by clicking corresponding option on Legend. Let say, the range of line A values is 0…3000 and for line B it is 0…15. When line A is hidden, …

And if you need that “invisible” (i.e. alpha=0) circle, for hit testing or whatever, then you can add it to the legend: p.circle(..., legend_label=name) It won’t “show up” there since it has alpha=0 but it will actually get its visible property updated by the interactive legend in a way that the d…

Please see this discussion, re: only_visible [image] Unable to change the y_range when changing renderer visibility Community Support Hi @Gilles the code you have presented seems somewhat overcomplicated relative to what you have described. So, why don’t we start with thi…

Hi @Bryan Thanks for suggestion. No matter how I create a Button, even if it just button = Button(label='change line') show(column(p, button)) with no additional settings I always get microscopic broken chart in top left corner of web-page (both in Chrome and Fiferox): [Screenshot from 2025-03-1…

@AlexGoody please provide a complete script of what your have tried so that I can actually try running it myself.

Data is pretty much simplified, but that not important since issue reproduced import random import sys import pandas as pd from bokeh import events from bokeh.io import output_file from bokeh.models import HoverTool, Line, ColumnDataSource, TapTool, CustomJS, CrosshairTool from bokeh.palettes impo…

@AlexGoody My suggestion was to follow the post I linked and let the detault auto-ranges do all this work, with only_visible set to True. It does not appear that you have tried that approach? I don’t think you would need any CustomJS at all that way. Please give the approach in the post I linked a t…

Oh… I misunderstood your point. I thought I need to apply the exact solution with the button… Do I need to simply add p.x_range.only_visible = True p.y_range.only_visible = True to script? To some specific place? Cause if to add it simply after p definition then it doesn’t work

Cause if to add it simply after p definition then it doesn’t work That’s because you add a circle glyph with alpha=0 that is not controlled by the legend, so never gets visible set to false. The only_visible property of data ranges corresponds to the visible property of glyph renderers. If a glyp…

@Brian added the complete script cause was not sure what exactly can affect… :man_shrugging: sorry for that :slight_smile: Now it’s working. Thank you!
