I'd like to draw a line chart based on two columns - let's call the regarded fields cats
and dogs
. I know I could create a third field called animals
and populate it but that seems to me as an ugly workaround.
I'm pretty sure there's no way to achieve that via the GUI so I'm hoping that editing the produced XML will open that possibility. As far I could understand this discussion, it's not possible but since it's old, I'm hoping that it's become possible since then.
Any luck on this one?
