Creating a Mix Chart
To create a Mix chart:

History Chart Overwrite Warning dialog box appears. To create new Trend charts and
Mix charts (the existing ones are deleted automatically), click both checkboxes. This
approach is recommended. Clearing either check box causes TCM to not overwrite that
Chart sheet. When you finish making your selections, click OK.

screen (horizontal), 1/2 screen (vertical), 2/3 screen (the default), or Full screen. Then click
