hello,

when i have a histogram plot and a curve plot of the same data, and when i zoom on the curve, the histogram shows nothing anymore ...
the preferred behaviour would be: show a histogram of the visible data points only. right ?

thanks,
greetings,
frank

Did you have tied zoom?  Histograms seem to work fine here with zooming, but I'm wondering if you expect that zooming a curve updates the histogram in a tied plot to only show the points visible in the zoomed curve.  That's rather complicated I think, and perhaps not worth the effort.

when i try to tie a histogram to a curve, the histogram zooms together with the curve in a very illogical way (try to scale along the X-axis like the curve iirc). I indeed tought that the expected behaviour was making a histogram of only the points that are visible in the curve. if that is not worth the effort, then maybe histograms should be non-tie-able

Curves are not tied though - plots are.  Plots can contain multiple curves, for instance, and the tie state really has nothing to do with the contents of the plot.

While the behavior requested here is inconsistent with the design of kst, it is related to other potential features, like being able to fit to only what is shown on the screen.  I am going to close this bug, and re-open one which more clearly lays out what I think we want.
