Thanks, Attila, for your response. I need the actual number of times the traces have crossed each pixel for analysis. An image file would work if I could use it to back out this information. However, there are two issues with this. First, I don't know the mapping between the RGB color values and the number of traces that crossed that pixel. I assume that the colors are chosen for the sake of visual clarity, not linearity. Secondly, I would want just the color plot with a black background so that the labels and markings don't get mistaken for a crossed pixel. And of course, I would need to know the time and voltage coordinate for each pixel. Since the plot here is generated from the internal array that you mention, and is exactly what I want, the simplest solution is to get that internal array as an export feature.
