I am using wheel_zoom (x-axis) and did set boundaries (on the x-axis).
After zooming in, I’d like to get the plot back to both boundaries when zooming out.
But the zoom out stops as soon as one of the boundary is reached.
Any way to customise so that zoom out does not stop until the second boundary is reached ?
Thx for any tips.
Hi,
AFAIK this mode of operation is not currently supported and it would take new development to make things (optionally) work this way. Please feel free to open a feature request on GitHub to discuss it:
However, if your interest is in restoring the original plot bounds, perhaps the "reset" tool is actually what you need?
Thanks,
Bryan

thank you for your quick answer, I will soon submit the feature request
As for the reset tool suggestion, it does not work and i am unsure why, but it seems to be related to using custom tick formatters.

Hi,
I can't imagine how a custom tick formatter could interact at all with the reset tool, but if the reset tool is not behaving as expected, please try to share a minimal complete test case that reproduces the behavior, it might be a bug that needs fixing.
Thanks,
Bryan

Ok i explored a bit: the y-axis is automatically adjusted on xpan and xwheel zoom with the code below.
However, that works only with the error in jscode (last line). The error prevents reset tool to work properly.
The best of course would be to be able to get rid of the last line, console.log(x); and have the y-axis tracking still working.
I likely do something wrong: without the generated error , the change in the y-axis is not triggered.
I did not find a way to trigger it.
from bokeh.plotting import figure
from bokeh.io import curdoc
from bokeh.models import ColumnDataSource,CustomJS
from bokeh.layouts import column,row
import numpy as np
jscode="""
var start = Math.floor(cb_obj.start);
var end = Math.floor(cb_obj.end);
var y = source.data['y'].slice(start, end);
var yv = [Math.min(...y),Math.max(...y)];
var dy = yv[1] - yv[0];
yrange.start = yv[0]-0.2*dy;
yrange.end = yv[1]+0.2*dy;
console.log(x);
"""
n=100
x = np.arange(n)
y = np.random.rand(n)+x/50
p = figure(plot_width=400, plot_height=200,tools = 'reset,box_zoom,xwheel_zoom,xwheel_pan')
cds = ColumnDataSource({'x':x,'y':y})
p.line(x='x',y='y', source=cds)
p.x_range.callback = CustomJS(args=dict(yrange=p.y_range,source=cds), code=jscode)
curdoc().add_root(p)
