Currently there is no way to do a scatter plot using bands with different resolutions. The best way to do this is probably some nearest neighbor calculation (cKDTree from scipy).

Tim also reported this as an issue. Would it be possible to produce a set of B03 files at 2 km resolution? Otherwise, we cannot compare it to other bands, and unfortunately, the visible band is a fairly popular band to use in comparisons.

Dave is looking at consolidating this with region extraction & masking prior to making histograms/scatter plots.

As you know, there are also several 1km bands (1, 2 and 4), so I don't think this is just a band 3 issue (but agree that's the most important). Thanks.

This should work properly in 0.5.1 and with all the other changes I made it should seem faster while switching between tabs and/or plotting for different layers. I chose to upsample any lower res data to the higher resolution layer's pixels. It's like nearest neighbor but I'm literally mapping a pixel's mercator X/Y coordinate in one resolution to the index coordinate (array index) in the other resolution.
