Toggling Series On or Off

You can toggle the visibility of a series by clicking on the series name in the legend. If a series has been set to invisible, the name of the series will appear in the legend with strikethrough text.

When series are toggled on or off the chart will re-scale the Y-Axis as necessary.

Saving a Chart as an Image

Click the "Export Chart as Image" button to convert the chart to an image and to display that image in a separate window. To save the image to a file, right-click anywhere on the chart in that window and click on the 'Save image as...' option.
