Hi There,
I'm getting stumped by what I think should be really easy.
I have a 180 by 60 rectangular dataset and I want this to be the vert_colors
on an idlgrpolygon. But how do I calculate the connectivity - shouldn't it be really easy for a simple rectangular dataset ?
ie, I have 3D cartesian coords: x(180,60), y(180,60), z(180,60) and some data
Density(180,60) that I want to be the vert_colors.
It works if I use 'style=0' but thats because this just plots 'dots' so the connectivity is not important. But for the standard surface 'style=2' it's not looking right. Should one need to define the connectivity for a simple 2D rectangular surface - it would seem to me that the default would be for this to 'just work' ?
Cheers
George.
