Hi everyone,
I'm trying to use a drop down menu in App Design to plot different channles from a .csv file. Essentially, it has a (time, fx,fy,fz) column structure. I have created the drop down menu button, and assigned Items and the corresponding values I want those items to have. However, I'm having trouble in the execution, as it seems that only one value is passed through properly, resulting in 2/3 graphs being completely broken. When I try to debug it by setting a different initial value, this is the error I get. I've researched it and there's not much info out there on how to fix it, especially since I'm seemengly doing a very simple thing. When I try to change the 'Value' from 2 to any other in the 'Items Data' list, I get the error.
The follwing is the UI component code generated by App Designer as well.
% Create AxisDropDownProcessing
app.AxisDropDownProcessing = uidropdown(app.PreprocessingTab);
app.AxisDropDownProcessing.Items = {'X', 'Y', 'Z'};
app.AxisDropDownProcessing.ItemsData = [2 3 4];
app.AxisDropDownProcessing.Editable = 'on';
app.AxisDropDownProcessing.ValueChangedFcn = createCallbackFcn(app, @AxisDropDownProcessingValueChanged, true);
app.AxisDropDownProcessing.BackgroundColor = [1 1 1];
app.AxisDropDownProcessing.Position = [67 648 50 22];
app.AxisDropDownProcessing.Value = 2;

I see the same behavior. However, I could use the button with the vertical 3 dots to the right of the Value and Items fields to modify the default selection.

It doesn't appear to work as seamlessly as perhaps it is eant to be but inputting them via the vertical 3 dot menu seems to bypass the issue.

Remove the quotes around the Value and Items names, and it will work the way you expect.
