Why is my column scatter plot missing some points?

If you have too many points on a column scatter graph with exactly the same Y value, Prism starts superimposing them, so you can't see how many there are. There are three ways to bypass the problem:

1. Drag the baseline to widen the graph
2. Make the symbols smaller
3. Make the gap between columns smaller, allowing more room for symbols

Adjust items 2 and 3 in the "Format Graph" dialog, which appears when you double-click on a symbol.

We have improved the way Prism arranges points in scatter plots in releases 5.04 (windows) and 5.0d (mac).
