Graph tip - How can I make a bar/column graph that also shows the individual data points?

Prism doesn't let you make a graph with bars or columns and also show the individual data points as a scatter plot. There is an easy work around, however.

Make a column scatter plot of your data and tell Prism to draw a line at the mean. You can include error bars if you want.

Adjust the size of the graph and the range of the Y axis at this point. Once you are happy with the graph's look,  use Prism's drawing tools to draw lines from the mean line of each data group to the X axis.

These lines are not attached to the axis.  If you resize the graph or change the axis range, you'll need to move and stretch the lines into position.
