The persistence window produces a nice color image that summarizes many traces of the captured waveform. Each pixel represents the number of waveforms that crossed that voltage level at that time relative to the trigger. Is there a way to get a matrix of that data? It is obviously stored somewhere to produce the image, so this should be low hanging fruit. I tried to use the data logger to capture this data, but all it gives is a header with general information.
On a related note, when using the logger to capture a series of traces, it stores the full trace, not just the part that is displayed. Since my data is localized to a small time slice, the huge files are a waste since only a small portion of them contains the information I need. Is there a setting to capture just the data displayed in the scope window? This is related to the above question because I only need the persistence data in the time range of the displayed image.

I am new to this, so apologies for my naivete.
