App designer: is there any way to get a cursor data point value in a colormap plot?

I am using app designer and when I plot STFT (colormap) there is no way to get any cursor data values.

I was wondering is there there any way to do so or it is not possible at all in App designer?

Dear Aiswarya,

Thank you for your response. Unfortunately, it does not work. I can get cursor data point value for regular plots but it is not possible to get these values out of a colormap.

Also, I am not sure how they use datacursormode in app designer because I think it is not supported in app designer and I am getting Invalid figure handle error.

Thanks.
