(Open) Office help needed

[m^2]

I have a spreadsheet with compression data that looks a bit like:
No code has to be inserted here.
I'd like to chart time vs. size and have a legend that lets you figure out what are particular points.
I spent like 2 hours on it, tried both OO.o and SoftMaker Office and can't make it work.
Any suggestions?

I tried todo the same a while ago(maybe last year?), i even went and asked on the OOo forums and they said it wasn't possible at this time.

Thanks for confirmation. I did it manually, it was 'just' 12 charts with 9 points each. Anyway faster than learning R.
