SPC Charts: Legend Tab

The Legend tab allows you to configure the chart's legend. The legend is a table at the bottom of the chart that summarizes data in the chart. By default, the legend shows each data source, its pen color, its description, and its value in the active time cursor. Using the Legend tab, you can customize the legend to show additional data, such as the high and low limits of the data source. You can also arrange the columns in the legend, specify the number of pens to display in the legend, and enable legend scrolling. The Legend tab is the same for all SPC chart types, with the exception of the Correlation chart. For information on the Correlation chart's properties, refer to the section Correlation chart properties.
