Kunal,
I asked the exact question a few days ago. Here is the response I got. Worked like a charm.
I don't know if that could be done in a config file, but it certainly can be done by altering the source. Take a look at hobbitd/hobbitgraph.c. Near the top there's a bunch of defines that tell rrdtool how to select the data:
#define HOUR_GRAPH "e-48h"
#define DAY_GRAPH "e-12d"
#define WEEK_GRAPH "e-48d"
#define MONTH_GRAPH "e-576d"
"e-48h" means "end-of-data minus 48 hours", which is the start of the range, the end of the range being the end of the data. Change those numbers to whatever suits you best - i.e. e-24h, e-7d, e-30d & e-365d.
You'll also want to look further down for blocks like this:
if (strcmp(val, "hourly") == 0) {
period = HOUR_GRAPH;
persecs = 48*60*60;
gtype = strdup(val);
glegend = "Last 48 Hours";
}
and fix those up. I guess that would be:
persecs = 24*60*60;
and
glegend = "Last 24 Hours";
for the 24 hour graph. Similarly for DAY_GRAPH, WEEK_GRAPH & MONTH_GRAPH. Go back up to the main source directory and re-run make, then copy hobbitd/hobbitgraph.cgi over to hobbit's server/bin directory.
Seems to work fine for me - I might even keep it like this... :)

Hi all,
Currently, hobbit shows graph for the following time intervals 48hrs, 12days, 48days, 576days.
Is there a configuration property to change these intervals ?
TIA,
Kunal
