I have an app, which i am devloping using appdesigner, I am trying to get x,y locations from a current image with ginput, however ginput is slow and dosent work seamlessly as it runs in the script

My main call is app, in the current window i defined a panel.

Here i call geoaxes as shown below:

    gx=geoaxes(app.Panel_3)  
    geoplot(gx,lat1,long1,'-r')%this draws a direct line
    hold("on")
    app.Panel_3.HandleVisibility = 'callback'
    [x,y=ginput(2)
    app.Panel_3.HandleVisibility = 'off'
    geoplot(gx,x,y,'-r')#draws an additional line as per user input

When the app opens, i can see that the cursor comes up but dosent go away after 2 clicks as expected. Is there something wrong with the way i am calling ginput?

Also, i am using MATLAB 2020b

Hi,

There is nothing wrong with the way you are using 'ginput'. The only mistake in the snippet you have provided is that there is a missing ']' in the below line which might have been a tying error

[x,y=ginput(2)  %error
[x,y]=ginput(2)  %right syntax
