Referring to object names in App Designer as elements of an array

In App Designer, I want to introduce the names of a series of objects (e.g. uifigures) in an array, and then refer to them by their index. For example:
PlotNames={'app.XY1' 'app.XY2' 'app.XY3'}
for iPN=1:length(PlotNames)
plot(PlotNames{iPN},X(iPN),Y(iPN))
end
but when I do this I get the error: 'Invalid first data argument.'
Is it possible to refer to object names in App Designer as elements of an array?

Hi Saeid,
In MATLAB, you cannot directly store object names as strings in an array and then refer to them. Instead, you can store the object handles directly in an array. This allows you to refer to the objects by their index without encountering errors.
Updated code:
% Assuming XY1, XY2, and XY3 are UIAxes in your app
PlotHandles = {app.XY1, app.XY2, app.XY3};
for iPN=1:length(PlotNames)
plot(PlotNames{iPN},X(iPN),Y(iPN))
end
I hope this solves your issue!

You can access properties of an object using a variable name using the syntax shown in the Reference Properties Using Variables section on this documentation page.

@Saeid: Your example code adapted to this approach would look like this:
PlotNames = {'XY1' 'XY2' 'XY3'};
for iPN = 1:numel(PlotNames)
plot(app.(PlotNames{iPN}),X(iPN),Y(iPN))
end
