Color by vector component only available from "Edit Color Map..."
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Selecting which vector component to color by (or whether to color by vector magnitude) should be available on the Display page for the data (somewhere near the Color by menu). It seems hidden on the "Edit Color Map..." page. Maybe the controls should be in two places (like the ones for data set visibility are).
