Creating spectral charts
You can use spectral charts to illustrate relationships between data points that might be hard to see otherwise. Spectral charts use colors to show ranges of values, so that high and low points are easily identifiable. For example, a company that sells three products can use a spectral chart to obtain a month-by-month picture of sales.
For information about modifying charts, see “Working with chart series.” For information about editing charts, see “Editing charts.”
