This preference sets the color or pattern of the current chart series. This is the color that is displayed for the series in the chart legend, if visible.
To change the chart colors:
Display the Chart Type tab of the Chart Preferences dialog. The Chart group is displayed in the middle of the page.
Open the Color drop-down list and select a color or pattern (see Setting Options Preferences for information about setting Crystal Ball to offer pattern settings).
Optional: Consider adjusting the chart type (Setting the Chart Type) and marker line settings (Showing the Mean and Other Marker Lines) for that series.
Optional: When settings for the current series are complete, follow steps 2 through 3 to customize settings for any other series in the chart.
