Thanks very much, I can now link X axis of ViewBox1 to Y axis of ViewBox2. Also, thanks for your quick response!
However I noticed following bug: I have to quickly zoom in/out in each ViewBox to "initialize" the linking. Else when zooming (or translating) in ViewBox1, there is a strange wiggling in ViewBow2 (instead of also zooming in). The wiggling is like a very fast zoom in / zoom out. As a workaround, when initalizing my widget I do: self.ViewBox1.scaleBy(1) self.ViewBox2.scaleBy(1) Which simulates the quick zoom in/out I had to do with the mouse. Now everything works as intended. But I find it strange that I had to do this to achieve desired behaviour. Did someone had a similar issue or can shed some light?
