Dynamically changing the bounds of an axes using sliders

Community Support

Hi everyone. I’m relatively new to Bokeh. Love it so far. At the moment, I’m using it to create simple stock price charts from Yahoo Finance data. The functionality I would like to add is to use widgets somehow (specifically I’m thinking of the slider) to dynamically change the x_range of my plots. More concretely, I’d like to select say ‘5’ on the slider and have the chart show 5 years of historical data and then select ‘3’ on the slider and have the chart update to only show 3 years of historical data. Is this possible? Thanks!

Alternatively, another potential solution would be for me to use the xwheel_zoom tool if I could set it so that the upper bound of the x-axis stayed fixed (e.g. was always the last date) while the lower bound of the x-axis changed dynamically. Is this possible?

Seems like a CustomJS callback would do that for you.
