Read x-axis info from SCP-generated virtual rasters

[jgrn307]

Hi there! An important feature using your tool for RS work is proper x-axis settings, particularly wavelength settings. I have two questions/requests:

1. Is there a way to assign x-axis values to the band numbers in a raster stack "manually" somehow?
2. Would you consider reading the semi-automated classification plugin's (https://github.com/semiautomaticgit/SemiAutomaticClassificationPlugin) x-axis info that are created when you create a band-set? SCP correctly reads e.g. Landsat/Sentinel/MODIS band info and assigns the layers the correct wavelengths, but your tool doesn't read that info when doing the plot. I'm attaching a screen shot of a Sentinel-2 band set with the wavelength info to this request.

Ideally, we'd like to be able to create a bandset with SCP, then use your profile tool to click various pixels and see the spectral signatures with the proper x-axis defined from the bandset.

Cheers!

Hi,
The solution to your first question should already be there. If you go to the "Settings" tab and under the "X-axis steps" section select "From string" from the drop-down list then you should be able type in a semicolon separated list of band numbers or wavelengths.

Regarding the second question, if SCP saves the wavelenghts in a text file with semicolon separated list then you can load it with the "Load from file" button.
