file retention graph

[pcroland]

Hi!

I created a graph for file retention:

Feel free to merge it somewhere in the php if you want.

Neat! Did you manually draw that? To actually merge that in I'd probably want it generated based on the settings inside the .php somehow

[pcroland]

I generated the graph in excel, then manually draw it, yes: https://widevine.is-a.fail/lS9ZXN.png

[Rouji]

Can't really put it in the repo as the static thing that it is, but I've put it on x0.at for now anyway. Looks good on desktop browsers and iOS (maybe a bit large), but somehow goes weird on Android, even inside the <pre>, so it still needs some fiddling though :/

I guess generating a simple SVG might do the trick for a dynamic graph that looks the same everywhere. But someone would have to be very bored to implement that.

[pcroland]

Just changing the graph values based on the settings should be okay I guess. The slope won't change unless you change the formula.

[Rouji]

The exponent is configurable and will indeed change the slope.

+1 for merging

+1 for merging

A static graph does not work for the general case, where the exponent is configurable. Simple example: it's a straight line for $DECAY_EXP=1
