Correcting Scaling Issues
Use the scaling feature in instances where numeric values in a chart are so long that they affect the display.
1. Preview your chart in the Chart Designer.
2. Under Scale, click to display the drop-down list of scaling options. In the example below, the scaling option used is "1000." 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. 
3. Click OK to display the chart in the dashboard.
Note: The scaling feature is available for all chart types, except pie.
