Hi Alexander,

thank you for the informations. I will have a look next days and I will
write you when I have a concept, so you can have a look on it. Thank you
for helping me.

Best regards,

Martin

<br>
To get a first idea for how to implement this maybe, have a look at <br>
CartesianPlotPrivate::mouseMoveEvent() in CartesianPlot.cpp. While being in <br>
the &quot;select&amp;zoom mode&quot; (switch to this &quot;cursor&quot; in the plot \
toolbar, select a <br> region in the plot and zoom into the data upon mouse release) \
we calculate <br> already deltaX and deltaY and show these values in the status bar \
