Hello, Im trying to list out children in plots of an uiaxis, but want the uiaxis to be user selected i.e. UIAxes, or UIAxes2 or UIAxes3 etc.

I have a dropdownbox with the following items in:

UIAxes, UIAxes2, UIAxes3, UIAxes4

Depending on whats selected, I then want to get the children of that axis, and this is my code:

ax=app.AxisSelectDropDown.Value;
ax=['app.',ax];                 
b=ax.Children    % b(1) is last object added to uiaxes

But Im getting an error

Dot indexing is not supported for variables of this type.

Seems like you mean this:

ax=app.AxisSelectDropDown.Value;
ax=app.(ax);
b=ax.Children    % b(1) is last object added to uiaxes
