For each Tag in the Easy Chart example above, lets create it's own subplot so the data is easier to view and analyze.
Once you add the subplots, put each of the different pens into a different subplot. Click on the Pens tab, select the Pen row, and click the Edit Pen icon . In the Subplot field, use the dropdown to select the subplot number.
If you would like to change the style of how the data is presented in the subplot, click the dropdown list next to Style, and choose from the several style options available. Click OK.
Repeat this step for each one of your pens, then press OK.
