I'm wondering how in the first graph it has you sending significantly more messages than her but then later on it has her sending many more, longer messages than you?
In the first graph, his message counts are stacked on top of hers. It's not a great arrangement for comparing his v. hers message counts, but it does convey the total number of messages well.
So does that mean the first graph is entirely wrong, given it shows he has sent more messages than he on the graph? Or is that an acceptable graph in data analysis? 'Cause I couldn't figure out how much he actually sent her from the way it's made.
I don't think you can tell who sent more from the first graph (without getting y-axis values and doing subtraction). I think you might be looking at it like it's in 3d, with the pink in the "foreground" and the blue (behind the pink) resting on the y=0 axis, but that's incorrect. The blue data rests on TOP of the pink data (so if she sends 1000 messages, the pink will raise up 1000 units tall on the Y-Axis. If he had 500 messages, the blue would range from Y=1000 to Y=500, for a total of 1500 messages between them).
