Description

https://metrics.torproject.org/users.html?graph=direct-users&start=2010-12-01&end=2012-09-24&country=sy&events=on&dpi=300#direct-users for example has a huge spike in the std dev graph, making the actual black line not so obvious, and the graph not so useful for presentations.

What's the fix? Do we chop off the graph at a certain point?

The gray area is just indicative of what the "normal range" os the number of users is. Would it be preferable to simply chose the range of the y-axis on the basis of the values of the number of users, rather than the gray zone? I do not see any significant loss of information in doing so.

Displaying the gray area and choosing the range based on the black line is possible, but requires some hacking.

What we could do for a quick fix is add an option to take out the gray area but leave the red and blue points in. See the attached graph. Would that help?

Sounds like we should put that on the todo list then (or try to get an excited volunteer to work on it).

It does help over the current situation, yes.

Actually, if we find an excited volunteer who wants to work on visualizations, I'd prefer him/her to work on interactive graphs based on metrics-web's data. Walter Kim's graphs are a great start. We should either get Walter excited about them again, or find somebody to pick up his work.

I think that concludes the ticket. Can we close it?
