app designer: how to index through multiple UIAxes

1. There are 5 UIAxes objects in an App added using the Design View
2. Component names are: app.UIAxes_1, app.UIAxes_2....
3. How do I index through each Axes component to update the plots?

Have tried:

app.plotHandles = gobjects([app.UIAxes_1,app.UIAxes_2,app.UIAxes_3,app.UIAxes_4,app.UIAxes_5])
for i=1:5
    plot(app.plotHandles(i),x(i),y(i));
end

Unable to resolve the name 'app.UIAxes_1'.

This has the error : 'Error using gobjects Inputs must be scalar numeric or a vector of array dimensions'

Answer 1

[Walter Roberson]

app.plotHandles = gobjects([app.UIAxes_1,app.UIAxes_2,app.UIAxes_3,app.UIAxes_4,app.UIAxes_5])

The gobjects() function only accepts size-related arguments -- the number of objects to create or the dimensions of the object array.

You should use

app.plotHandles = [app.UIAxes_1, app.UIAxes_2, app.UIAxes_3, app.UIAxes_4, app.UIAxes_5];

Hey... just put in the startup of your app the code below.

app.plotHandles = findall(app.UIFigure, 'Type', 'axes');

There is a risk that the order might not be what is needed.

There is a risk that there are other uiaxes as well.

There is a risk that there are standard axes that are not uiaxes.
