PlotViewController = new PlotController();
PlotViewController.UnbindAll();
PlotViewController.BindMouseDown(OxyMouseButton.Left, OxyPlot.PlotCommands.ZoomRectangle);
With the above code, when the data disappears and shows a blank, if I reduce the overall height of the control, the data will reappear; however, when I restore the control to its original height, the data disappears and the blank area returns.
