Hi Naomi,
You are right, neither the correlation plot nor the tri-color map plots correctly export data. I'll add those to the To Do list.
You can export the data for each map from a single map display.
To write out a text file with correlated intensities as shown in the correlation plot, you could do something like this in the Larch buffer:
> print( map001.filename)
> fe_map = map001.get_roimap('Fe Ka')
> zn_map = map001.get_roimap('Zn Ka')
> write_ascii('correlaton.txt', fe_map.flatten(), zn_map.flatten(), label='Fe Zn')
Note that as the map files are read in, they'll be named 'map001', 'map002', etc - you can print the filename to see that you have the right one.
The fe_map and zn_map arrays will be 2D arrays so you have to "flatten" them to write them out to a text file.
If you read that text file back in, you can make a single scatter plot, as shown in the correlation plot window:
> cdat = read_ascii('correlation.txt')
> scatterplot(cdat.fe, cdat.zn)
Yeah, that's a little bit of typing code, but it will let
