Use the scaling feature in instances where numeric values in a chart are so long that they affect the display.
Note: The scaling feature is available for all chart types except pie.
Preview your chart in the Chart Designer.
Under Scale, click to display the drop-down list of scaling options.
In the example below, the scaling option used is 1 million. Notice the change in the display of numeric values when scaling is applied. Users of the chart can see actual values when they hover over the bars in the chart.
