When assigning the item in the Appdesigner, for example,

[x,y]=ginput(app.UIaxis,2);

it reminds the extra parameters. So how to obtain the coor of the plot using mouse interaction in the uiaxis? Any suggestion?

Aren't there still issues w/o an addressable target to ginput when there are multiple axes, UIAxes or not, when want/need to programmatically set with which the user is to interact?

There's a long discussion in the thread linked to in which it appears valid use cases are presented -- I didn't take the time to study those in excruciating detail so may have come to wrong conclusion, but seems like the target to address can still be an issue, visible or not.

Now that you're on board, I'm sure all these nits will be fixed sometime next week!!! :)
