I am having difficult adding labels/titles to the vertical axis of a scatter chart. I am using Excel 2010 and Windows XP.

I am trying to chart the milestones for multiple projects on one chart.

Here is the chart that I have:

First_Chart.png

Here is the chart that I want (manually edited what I have):

second_chart.png

Here is the data:

Any help would be greatly appreciated! Thanks!
