Charts with two axes feature a line chart superimposed upon a column or area chart and show a different value axis (y axis) for each chart. The axis on the left side of the chart belongs to the first data series listed in the Chart Data Editor, represented by a line, and is called Value Axis (Y1). The axis on the right side of the chart belongs to the second data series listed in the Chart Data Editor, represented by columns, and is called Value Axis (Y2). The Chart inspector provides controls that allow you to format each of the axes individually.

Mixed-type charts present a single chart in which each of the two series can be represented as a different chart type. For example, one data series can be represented by a line while the other data series is represented by columns.

For both 2-axis and mixed charts, only a single data series can be represented by each chart type. Either data series can be represented as a column, line, or area chart.

To change a chart type in the figure:

  1. Select the data series for which you want to change the chart type.

  2. Click Inspector in the toolbar, click the Chart inspector button, and then click Series.

  3. Select a chart type from the Series Type pop-up menu.
