How hard would it be to implement a function that would chart "posts per month" on an individual basis? I've always wondered how much more I've been posting now, than when I first joined LJ, but other than doing the math shorthand, there's not an easy way to calculate that.
It appears that LJ uses GNUPlot, or something similar, to generate graphs for other things -- albeit perhaps not on the fly -- so it doesn't seem like it'd be hard to implement.
Some people might argue CPU time would be a factor, but you could maybe allow this sort of thing only on paid accounts. Or just take it into consideration for future development.
