Quick way to see request time distribution

Ever wondered what's hiding behind those average numbers in Pinba reports?
Well, so have we. I spent some time and came up with this result:

0.00:                                                    (612, 0.99%)

0.05: **                                                (2239, 3.62%)

0.10: ****                                              (3401, 5.51%)

0.15: ****************************************          (25431, 41.17%)

0.20: ************                                       (7806, 12.64%)

0.25: ********                                          (5823, 9.43%)

0.30: ****                                              (3347, 5.42%)

0.35: **                                                 (1505, 2.44%)

0.40:                                                   (1091, 1.77%)

0.45: ****                                               (2951, 4.78%)

0.50: **                                                 (1238, 2.00%)

0.55:                                                   (1019, 1.65%)

0.60:                                                   (746, 1.21%)

0.65: *                                                  (662, 1.07%)

0.70:                                                    (575, 0.93%)

0.75:                                                    (486, 0.79%)

0.80:                                                    (381, 0.62%)

So what do we see here? Even though the average request time is 0.308 sec, the majority of the users actually get served faster than that - in about 0.10-0.25 sec.
There's also an interesting peak at 0.45 sec, I'll have to use conditional reports to explain it.
And here is the script I used.
