MATLAB: Cannot find Brush Data property for app.UIAxes

appdesignerbrushed dataMATLAB

Hello,

I'm simply looking to get "brushed" data into a variable. I'm using appDesigner, and have built a GUI which plots data. Now I want the user to be able to select a portion of that data and store/manipulate it how they want. I'm not sure if it's because I'm using the appDesigner feature, but I cannot find a BrushData property for the data that is brushed on my current axis.

K>> app.UIAxes.BrushData

Unrecognized method, property, or field 'BrushData' for class 'matlab.ui.control.UIAxes'.

Thanks for any help!

The Brush Data property is located within Children:

app.UIAxes.Children.BrushData

MATLAB: Hi guys, I’m trying to create a multiwindow app. It’s the first app but I’m taking this error. How to solve it

I beleive your error is here

% Code that executes after component creation
        function startupFcn(app, MainApp, a, b, c)
            % Store main app in property for CloseRequestFcn to use
            app.CallingApp = mainApp;    % <----------------------------- HERE

Should be

            app.CallingApp = MainApp;   % with capital M

Make that change, save the app, close the app, restart it, and test it. If the problem persists, I'd be glad to look further.
