MATLAB: How to use uigetfile to plot the contents of a file

Question

Hi all

how can I use the uigetfile to chose a file and plot its contents

I defined the public property for the push button and I have also a check box that in case it's checked , the plot should be held to be compared with the next one to be plotted

so the property :

 properties (Access = public)
        
        selecplot=''%Path for plots
    end

then in the pushbutton for plot :

        % Button pushed function: PlotButton
        function PlotButtonPushed(app, event)
           switch app.HoldPlotsCheckBox.Value
               case 0
                  app.selectplot= uigetfile();
                  drawnow;
    %             FocusUIFigure(app.UIFigure)
                  app.UIFigure.Visible = 'off';
                  app.UIFigure.Visible = 'on';
           end
        end
        % Value changed function: HoldPlotsCheckBox
        function HoldPlotsCheckBoxValueChanged(app, event)
            value = app.HoldPlotsCheckBox.Value;
            
        end
        

with the above I get the error :

Error using matlab.ui.control.internal.controller.ComponentController/executeUserCallback (line 309)
Error while evaluating Button PrivateButtonPushedFcn.
Unrecognized property 'selectplot' for class 'app'.
Error in app120/PlotButtonPushed (line 1969)
                  app.selectplot= uigetfile();

Answer 1

your property block shows that your property name is selecplot while when you use it, you used selectplot.
