the amazing vanishing history plot run markers
Issue #255
wontfix
When I pan this plot to the left (to see newer data), the vertical bars for run indicators suddenly disappear. I do not know if this is a bug or a feature. K.O.

The programming is currently done such that a maximum of 200 run markers are drawn. If there are too many run markers, the screen becomes black and you don’t see any history data. At that level, you don’t care about runs any more, so they are simply removed. If you zoom in on the time axis, they re-appear. Now if you are close to the 200 limit, the run markers might “flicker” on and off if you drag left and right.
I don’t have a much better idea right now how to handle this.
