Put X values into column A starting in row 2, Y1 values (temp) in column B
starting in row 2, and Y2 values (storms) in column C starting in row 2.
Leave A1 blank, but put labels in B1 and C1.
Select this range, or a single cell in the range, and start the chart
wizard, choose your chart type, and continue through the wizard. If you have
problems, post back.
