Column 1: Date

Column 2: First Data corresponding to the adjacent date in column 1

Column 3: Date

Column 4: Second Data corresponding to the adjacent date in column 3

I tried a scatter chart with two series, the first with column 1 as X axis and column 2 as Y axis, and the second series using columns 3 and 4, but instead of using the data in columns 1 and 3 for the x axis it uses the row number of columns 2 and 4.

How can I chart this correctly?

Thanks in advance.
