EnamoRed,
Measurement Studio installs a help file which has a reference guid for all members of each class. You can look through this to find more information including all methods and propeties available to a class. This is where you can find information on programmatically changing this. These settings are part of the Axis class (XAxis and YAxis for the waveform graph) and are called MinorDivisions and MajorDivisions. If you want to edit these from the Form directly, just right click and go to the properties for each of these Axis and you will be able to change the color and turn this off or on. If you want to do this programmatically, check out the Measurement Studio help for the methods or properties you would need to use.
