App designer places code (grayed out) that shows an error. I will note that the code ran fine before I saved and closed it out and then later restarted the app. I think the issue might be related to the fact that I had a callback that used the delete function which is used to close the app.

The line that show the syntax error is the following and bold in the full code listing:
app.RawdataPlotterAppUIFigure.CloseRequestFcn = createCallbackFcn(app, @delete(gcf), true);

endApp designer places code (grayed out) that shows an error. I will note that the code ran fine before I saved and closed it out and then later restarted the app. I think the issue might be related to the fact that I had a callback that used the delete function which is used to close the app.

The line that show the syntax error is the following and bold in the full code listing:
app.RawdataPlotterAppUIFigure.CloseRequestFcn = createCallbackFcn(app, @delete(gcf), true);

end App designer places code (grayed out) that shows an error. I will note that the code ran fine before I saved and closed it out and then later restarted the app. I think the issue might be related to the fact that I had a callback that used the delete function which is used to close the app.

The line that show the syntax error is the following and bold in the full code listing:
app.RawdataPlotterAppUIFigure.CloseRequestFcn = createCallbackFcn(app, @delete(gcf), true);
