Bokeh CAMD Reset Behaviour

[Will-Cooper]

From @dr-rodriguez

if you change up what the CMD are plotting and then click Bokeh's reset view button- you can end up in a situation where no data is shown unless you zoom out. What I think is happening is that Bokeh's reset view is acting on the original data and so the axis limits are saved there for purposes of resetting. Changing what you are plotting does not update this and so you end up having to zoom out and re-find your data if you click that button. I had expected that to be more of a zoom to show all data rather than go back to what was first plotted.

Could do with overwriting the default reset behaviour to act in a more naturally predictable manner.
