How do I plot two curves on a single XY scatter chart?

[Puzzled]

I have set out two blocks of data and want to plot the curves each of them
produces on the same XY scatter chart to make comparison easier. Thanks in
advance.

make the chart with one set of XY values. Select the second set and copy.
Select the chart, use Edit menu > Paste Special, add the data as a New
Series with Category data in first row/column.

It's a best practice to use columns for your data, so the first curve would
use A and B, the second C and D, etc.
