Actually, plotmarkers.txt was written a long time ago, so the way I have
decided to do it now is a bit different:
- Alt+Leftclick in data/zoom modes creates a plot marker - any of the
other mouse actions still work
- Plot markers are vertical only right now, should they also have a
y-component as well (I am not sure how "jumping" left and right to
makers would work in that case), or should there be 2 types of plot markers?
- Currently Alt+right arrow and Alt+left arrow jumps to makers (because
Alt+leftclick created them), and the menu items are disabled if there is
no marker to jump to. I'll change it to use Pgup/Pgdown, and have
automatic markers at the beginning and end (but what happens to the menu
items after a jump to the beginning/end)?.
- There are public functions in Kst2DPlot that events can use to
create/retrieve/remove plot markers.
Triggering was actually supposed to be a separate thing from plot
markers, so I am not working on them right now.
