I need to make a dates (on x) vs. durations of time (on y) plots and need to have smart formatting for the y axis. My y data is in the database in the format: '0:00:02.994000', (that is, 2.9 seconds) and I'd like the y axis to be expressed in ticks of, e.g., "2 hrs", or "10 minutes", or "25 seconds", whichever is applicable...see below.
The data could range from as little as a few seconds to more than 12 hours. Sometimes there will be outliers that are in a different unit. E.g., there may be a plot in which most durations are 1-3 hrs, but now and then there is a datapoint of 5 minutes, or even 30 seconds. Or it could be another one with mostly datapoints in minutes, but an occasional long or short one in hours or seconds. I want to pick a good (dynamic, for zooming) way to format the y axis. There are two issues: 1) Should I analyze the data to see what units the majority of datapoints are in and then use that as the y axis units before zooming? That is, if most are durations of minutes, then the y axis should be given in minutes. If most are in hours, the y axis should be hours, etc... This way the formatting is appropriate for the majority of the data displayed. 2) If a plot's y units are given in terms of minutes (because of point #1), but a user wants to zoom in on a datapoint that is only a few seconds, I'd like the formatter to change the y scaling to be in terms of seconds. I don't want to have express durations on the y axis as anything like "0.0335" minutes, but rather "2 seconds". Does (1) seem like the right approach? And for 2, is there already a formatter that is appropriate for this or could be adapted to it? Suggestions welcome.

It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense.
