I recommend that you begin to use Control Chart Builder. As an example, I opened Big Class, selected Analyze > Quality > Control Chart Builder. I simply drag the measurement to the Y axis or inside the plot frame to get the XmR chart:

You can select another column with categories and click By. Click Done when you have finished making your charts.
