For those interested in metric chart type discussion between development and UXD, I have recorded the G+ hangout.
Hi all,
Following the hangout.
At the risk of looking simple minded, I find the whiskers and whiskers and bars graphs a little complicated :)
I may not already fully understand our users need but I find simple line graphs eloquent enough as a default.
I understand the concern of not giving the feeling to our users that we take "continuous" measures. In the past I have used drraw (a popular front end for RRDtool) and this is how line shapes look like in this tool:

I don't know if this type of shape is possible with d3js.
Just wanted to share my opinion.

Actually, thinking about this, I think this type of line chart gives us a nice way of dealing with the "level of detail" discussion we had some time ago. The more in detail you look at such graph, the more blocky it is going to look. This way you clearly see that the data collection is not continuos yet you don't sacrifice the superior readability that the line charts have over the barcharts (when it comes to min, avg, max in a single graph).
I did like the concept of adding additional layers of information into a single graph as Harlan showcased, but I think we need to strive for the maximum readability of the graphs, which, I must agree with Thomas, the barchart with whiskers doesn't offer - the graph is imho overly crowded and doesn't easily convey any trending information hidden in the data.

Yes, the simplicity and and accuracy of this type of line chart does make sense. I do like this better than the standard line chart where values are interpolated and may give somewhat of a false sense of trend (especially with spiking data).
It feels like there are two camps forming on charting: 1) simple interval(blocky) line charts (non-continuous) that show trending data 2) sophisticated bar/whiskers charts that show discrete intervals of data
We are working on a toggle between the two chart types to get simple/advanced charts.
Harlan & Catherine, can you create a mock-up of this interval line chart (perhaps modernizing it a bit)?
Then I'll incorporate that into the code.
