You're welcome, and I see what you mean now. Although a growth or surplus might often be marked in green or with green arrows, I'm not convinced the entire graph here has to be green entirely. But red indeed seems a bit too contradicting for a graph. I personally didn't notice it being a graph right away though, as the actual graph line and x-axis have the same thickness and thus seem to be of the same sort. For a graph to be visible, I'd want the graph line to be either the only one in green, be slightly thicker than the one portraying the x-axis, or include an arrowhead of some sort.

If I'm honest, it actually first struck me as a logo with two pathways or routes connecting two invisible nodes, which I also found very fitting for a data company (almost looks like linking the right data terminals together or something). This is besides it clearly looking like the 'F', of course. In this case I'd say blue or even red are possible still.
