You can add the chart legend using the <Legend> element tag which is defined as a child node of the <Options> element tag.

This sample chart is to show how to display and undisplay the series data when the chart is initially displayed. If you want to undisplay a series data with having the legend item of the series data unchecked, then you must set the value of the visible to "false"
