Created attachment 125760 [details] Video of zooming and draging the plot with minimum success. Trying to zoom or drag a log-log plot will cause the plot to either exaggerated or too little. This seems to effect log-log plot significantly. See log-log plot file and video as example.

Git commit 5b892796801802e17a18a46c0242219e98e760f6 by Alexander Semke. Committed on 22/03/2020 at 15:51. Pushed by asemke into branch 'master'. [worksheet] properly change the plot data ranges with zoomig in the plot with log10 scales. The same fix needs to be done for other scales and also for shift functions in the plot.

Zoom on log-log plot is now smooth, however if I zoom out too much to like 10^-300 labplot will crash, maybe set a limit to how much uer could zoom out or something. Dragging on log-log plot is still not smooth.
