More Than One Data Series

CHARTS WITH MORE THAN ONE DATA SERIES 

Excel can plot several data series in the same chart (the upper limit is 255 data series in a chart see Some Chart Specifications at the end of this chapter). If the values in the data series are similar in magnitude, then plotting two or more sets of data is not any different from plotting one set. If the numbers are very different (for example, if one set of y values is in the range 1-10 and the other set is in the range 0.001-0.010), you must use a chart with a secondary axis (see Charts with Secondary Axes later in this chapter).
