We are in the middle of investigating the issue you have described. While we do that, I would like to quickly give you an idea of how to resolve your second query. You can use the InteractionModeDefault property of the graph to interact with the graph without using the keyboard. We do not provide a built-in toolbox like LabVIEW does, so you will have to create the buttons to represent the interactive actions yourself. In the Click event for each corresponding button, you can set the InteractionModeDefault property of the graph to the appropriate value. For example, in the button Click event of the zoom button, you could have -
waveformGraph.InteractionModeDefault = GraphDefaultInteractionMode.ZoomXY;
Similarly in the button Click event of the pan button, you could have -
waveformGraph.InteractionModeDefault = GraphDefaultInteractionMode.PanXY;
Hope this helps.
