You should change the y axes from raw count to percentage of total count. Once you do this, I think the other authors' commits will look more spread-out.

Yes, you second suggestion is a more natural representation of the working hours -- a day starts from the morning instead of the mid-night (for most people). For the histogram, actually I'm not a regular user of <code>ggplot2</code>, and I didn't check <code>stat_bin()</code> carefully, but after your reminding, I found a weird behavior of it which confused me: <code>qplot(1:10)+stat_bin(binwidth=1)</code> will produce a histogram which is not flat... :shock: Thanks for your reply, Kevin.

Here is an equal-bin-width version using <code>lattice</code>: <pre>library(lattice) histogram(~hour, data = subset(hour.data, author == "ripley"), type="count", breaks=0:24-.1, scales=list(x=list(at=c(0,6,12,18,24))) )</pre> Your graph does a nice job of answering the question. Ripley usually quits working by 12:00 and almost always by 1:00 AM. He almost never starts before 5:00 AM. Shifting the 'window' from 0-24 hours to 4-28 hours provides a different (more natural?) perspective on Ripley's 'day': <pre>hour2 <- subset(hour.data, author == "ripley") hour2$hour <- ifelse(hour2$hour < 4, hour2$hour + 24, hour2$hour) histogram(~hour, data = hour2, type="count", breaks=4:30-.1, scales=list(x=list(at=c(0,6,12,18,24))) )</pre> Kevin Wright I don’t use ggplot2, so maybe I’m wrong, but it does not appear that ggplot2 is respecting the bin width of 1 hour.

Shifting the ‘window’ from 0-24 hours to 4-28 hours provides a different (more natural?) perspective on Ripley’s ‘day’:

hour2 <- subset(hour.data, author == "ripley")
hour2$hour <- ifelse(hour2$hour < 4, hour2$hour + 24, hour2$hour)
histogram(~hour, data = hour2,
          type="count",
          breaks=4:30-.1,
          scales=list(x=list(at=c(0,6,12,18,24)))
          )
