Bug Description
On the OpenStack Health front page there are currently 2 line graphs, which mostly don't tell you want is going on. Data failures aren't really line graphs, they are interesting only as aggregates.
What you really want to know is "what's the failure rate trends" and "how sure are we of that".
What the failure rate trends is would be best expressed as stacked bar graphs (pass/fail). You also want to know, at the same time, how sure you are of that number. One way that could be done is with opacity. If we make the bars more transparent if we have less than a reasonable amount of data, that would be extremely useful.

This is an interesting idea. Do you think this chart could replace the two charts we have now? I'd definitely be interested in combining them, since they're essentially showing exactly the same data while taking up almost the entire front page.
Also, it looks like nvd3 does support stacked bar charts, so this should be technically feasible. I believe we can also pass in transparency as part of the color field we're already using when we generate the chart data. Example is here: http://
