Answer

Set up your data like this to start with: 50 100 150 200 1760 63 58.6 54.5 50.7 1150 40 37.2 34.6 32.2 880 29 27 25.1 23.3 1760 4 7.5 10.4 12.9 1150 2.6 4.8 6.6 8.2 880 1.9 3.4 4.8 6

Highlight the entire selection and choose your graph (2-D line?)

in Excel 2007, right-click on the graph, choose select data and then click switch row/column. Next, you'll need to select one of your HP data lines and right-click and choose Format Data Series. In the pop up menu, choose plot on secondary axis. Repeat for the rest of your HP data lines.

Inor earlier, after you choose the chart type from the wizard and select next, choose Series in Rows from the Data Range tab. As above, select an HP data line, right-click and choose Format Data Series. Choose the Axis tab and plot series on Secondary axis. Repeat as necessary.
