After binding a chart to a dataset in the spreadsheet, SAP BusinessObjects Dashboards makes up a scale on the y axis by default, based on the lowest and highest values in the visualized dataset. The problem with this auto-scaling is that it creates a y-axis that doesn't start with 0, which may cause a bad interpretation of the data.

In the following screenshot, the same results are presented in two bar charts. The chart on the left-hand side gives the indication that Product B has performed a lot better than Product A; the bar is more than two times larger! This is, of course, wrong, as the y-axis starts at $470,000. The chart on the right-hand side shows a version that is much more useful for analysis.
