24h graphs instead of since midnight.

[lpaseen]

I'm trying to get graphs for the last 24h instead of since midnight but can't find any setting for it.
Is it possible?

Yes, try the day_ago_to_now

Or I guess better yet would be hour_ago_to_now, and specify the time_ago as 24

hour_ago_to_now = As of skin version 1.2. Use with time_ago to specify the number of hours ago to chart up until the current time. Example: time_ago = 5 would chart 5 hours ago to now.

At first I couldn't get it to work but then I realised "time_length" and after changing that from "today" to "90000" it now works
thanks
