How to detect the calling axes from context menu using AppDesigner

Hello Folks,

I hope you are all staying safe out there.

I am in the middle of a development project. So I have been posting several questions today (my apologies).

I am using App Designer to make an interconnected series of GUI's. One of the GUI's has many axes in it. I want to create a simple Context Menu that I can share between the different axes. I want the callback to get the current x and y limits of the axis, remind the user what they are, then accept input from the user to change it to something else. However, I can't seem to figure out how to get the handle of the axes within which the context menu was triggered from inside the callback. I have searched, but failed to find anything on this topic that I have recognized to be within the App Designer construct (lots of GUIDE construct posts though). Could any of you point me in the right direction?

Best regards,

Kris

Assign the object of ContextMenu to the axes property ContextMenu.

Refer to Context Menu for Specific Component example.

Thanks, but that does not answer my question. Anyone can assign the same callback function to multiple objects. How can I programatically distinguish between which object that instantiated the callback?

Use event.Source.Parent.CurrentAxes.XLim to access x limit of the current axis, which triggered the context menu.

Event property "Source" is the context menu which triggered the event.

Context Menu property "Parent" is the figure on which Context menu was triggered.

Figure property "CurrentAxis" is the axes on which the context menu was trigeered

Axes property "XLim" is the vector of limits in x axis for plot.

Hi Ayush,

Many thanks for the quick reply! Your solution was mostly correct. Just needs an extra "Parent" in there to back out of the context menu list panel.

XLimits = event.Source.Parent.Parent.CurrentAxes.XLim

Thanks again!
