The axis is linked to the viewbox so I am not sure if what you want can be done or not. Rotating the viewbox causes a mess. This is probably an issue you will just have to work around by setting the axis range to variables that are named according to how you want and updating those, or whatever solution you want but I don't think pyqtgraph can do this natively.
If it helps, the viewbox function .childrenBounds() returns the xrange, yrange as you want them so that xrange is the range on the left axis and yrange is the range on the bottom axis. If you can get the graph to update so that the viewbox left axis is the same as the child left axis then what you want to do will be done. Not sure how to do that. Maybe Ill look when I am not at work. On Tuesday, July 25, 2017 at 4:49:57 PM UTC-6, m has wrote: > > Dear Patrik, > Thank you again for your detailed reply.
