Apple Keynote- Help with charts

[masterwok]

Hi
I was wondering if it is possible in keynote when you are making charts to put two sets of data in the same chart even if they're x axis values are not the same i.e.
data A data B
x y x y
0 1 0 2
2 4 3 5
5 6 6 10

and then put them in the same chart so you can compare them, even though the data is not taken at the same x points. Haven't been able to find a solution so far and I'd be really grateful if someone could help me.....


Thanks!
