It is typical when looking at time series (in particular financial time series), that as one pans left or right, the range of yaxis changes to fit the min/max in the current view + some upper/lower gap. I note that bokeh does not do any adjustment of the yaxis range unless the pan is moved vertically.
I assume this behavior is on the javascript side and hence requires a new mode or widget with this sort of behavior. In short, looking to have a mode of panning that:
- adjusts the range on the y axis in to contain all visible glyphs in the visible x range
Further, is useful to be able to adjust the x zoom, so that can lengthen or contract the width of the visible window in x units (usually datetime for me).
I know the machinery to adjust the range, pan, etc is there, the question is how to wire this up & create a new panning mode or an alternative plot area?
Thanks
