I have a nice scrolling graph working in my app, I can zoom and restore. I would also like to pan back into history. Are there any examples on how this can be done. I assume it is based around changing the start and end time. I tried just turning of the scroll and changing the start and end time. Any clue's would be appreciated
If you change the coordinate systems start and end time, followed by the UpdateDraw method call, the graph should redraw acoordingly. Are you calling UpdateDraw? See the QCChart2D example SwingExamples.LinePlotScrollBar, or the QCRTGraph Polygraph example.
