Interactive data tip specify x and y location

Hello,

I would like to plot a heatmap or an image and use data tip where I can manually enter the x and y location in a sperate window and get the data tip displayed and/or the z-coordinate displayed in the image or in a new window.

So I would interactively enter different x and y location and always get the correspoding z value.

How can I do this?

Thanks.
