If you’re trying to build a chart with duration as the metric and it’s not working, then the reason is probably that you’re trying to get values from result.duration. Use meta.duration instead.
Statements encode the
result.duration property as a
string in
ISO 8601 format: e.g.,
PT59.14S = 59.14 seconds. In contrast, statements keep the value in the
meta.duration property as an
integer: e.g.,
59140 = 59,140 milliseconds. Because
meta.duration is a number, you can use it to calculate the heights of columns in a bar chart.
Duration Conversion Factors
If you want to show values in units other than milliseconds, then in Chart Builder, under Data Settings > Metric Scale, enter one of these conversion factors:
- 0.001 seconds
- 1.66667e-5 minutes
- 2.77778e-7 hours
- 1.15741e-8 days
In Metric Builder and List Builder, you do it by adding an inline mathematical operation in the title or subtitle: e.g., ${value.metric * 0.001}.
In VQL, you convert duration by adding a stage that performs the needed math: "$addFields": {"metric": {"$multiply": ["$metric", 2.77778e-7]}}.
