Excel includes an impressive graphing capability that can turn the dullest data into outstanding charts, complete with all sorts of whiz-bang do-dads to amaze your friends and confound your enemies. While Excel can automatically handle many of the mundane tasks associated with turning raw data into a chart, you may still want to change some elements of your chart.
For instance, you may want to change the scale Excel uses along an axis of your chart. (The scale automatically chosen by Excel may not represent the entire universe of possibilities you want conveyed in your chart.) You can change the scale used by Excel by following these steps in Excel 2007 or Excel 2010:
Figure 1. The Axis Options of the Format Axis dialog box.
In Excel 2013 and later versions, the steps are different:
Figure 2. The Axis Options in the Format Axis task pane.
Note that in order to adjust the Bounds and Units settings, Excel needs to recognize the data in an axis as a range of values (e.g. dates). There will not be the option to change Bounds and Units if the data is recognized as discreet values by Excel (e.g. item names).
