QGIS properly displays all of the points in the .shp file and clicking on the "i" button and then on one of the points displays its information at the right-hand side:
The only thing missing is the "M" value. I know this is probably a very basic question but I can't find any information about it anywhere: How do I get access to the M value?
I don't want to edit it or create new ones, I just want to see the existing one. Is there maybe any type of table that has a list of every point in the .shp file and all of its values (XYZ, M, name,...)?
