DPlot

Hi. I am new to this software. Dplot has generated 3D surface plots from X,Y,Z data. When I use the crosshairs, I see the additional data points Dplot has generated. However when I try to export the data values from the edit>copy>data values menu, I am only able to copy my input data.

How do I copy all of the data dplot has used to generate my surfaces? thanks

DPlot hasn't actually generated any new data in this case. With your input data, DPlot generates a triangular mesh using your X and Y values. Each triangle is considered planar. When you move your cursor across the plot what you see in the status bar is X,Y converted from mouse position and the corresponding Z for the triangle that the cursor is over.

If you want to save interpolated points, try Options>Generate Mesh. That command will produce a new surface plot with points on a rectangular grid at the spacing you specify. The linear interpolation method works the same as moving the cursor across the plot: all triangles are considered planar. The "bivariate" method can produce a smoother surface, but might require some experimentation. It is prone to producing large fluctuations in the surface if your input is "rough".
