TV type routine that can use irregular x and y coordinates? [message #94163]

Hello,

I currently have a plot routine that plots up f,x,y data (f at least is a 2D array, x and y can be 1 or 2D) as an image using iterations of polyfill. x and y don't have to be regularly spaced of course, they can be log-based coordinates.

However, this process takes some time with million point datasets, even plotting to a pixmap and then copying to an actual visible window using device.

Is there something like TV or TV image that would handle x and y coordinates?

I've spent some time on this without coming up with anything that works well and I suspect I'm trying to re-invent the wheel here...

Thanks,

Mark
