About the Data Series Tab
Use the Data Series tab on the Graph Window Options dialog box to change the appearance of data series. The software can display multiple data series that share common X and Y axes in a single graph window. Use the following options to work with the data series:
• Graph—Select a graph or subgraph whose data series you want to customize.
• Data Series—Edit the label for the selected data series. To change the color of the graph's points and lines, click the color selection buttons. You can also modify the points' style and interpolation and the lines' thickness.
• Legend—Turn the legend on and off. If you want to change the style, color, and size of the font, click the Text Style button.
