3D surface charts with Gnuplot
 

Hello,

I have just started to use Gnuplot to generate 3D surface charts from the data calculated by my programs. I wonder if someone knows if it is possible in Gnuplot to read the screen coordinates from a 3D surface chart? So, if you place a pointer to a certain location on the chart, its X, Y, and Z coordinates can be evaluated and displayed.

Thank you.
