Selecting a UIAxes from a drop down box and assigning it to ax to be called by other funtions

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
