Defining Chart Axis Labels
You can define and format labels for the primary and secondary axis in a chart. For a combo chart, you can specify and format a secondary axis label. You can also display and format metadata labels.
Note:
A primary or secondary axis label enables you to specify a custom range of values on the axis.
Note:
A chart axis plotted in Bar, Line, and Combo formats will auto-scale if the primary or secondary axis Min, Max, and Step fields are empty. By default, when the minimum value of the chart data set is within 5/6th of the maximum value, the chart auto-scales to draw attention to the differences in values. To override auto-scaling, enter values in the Min, Max, and Step fields.
