You will need to chain a few functions together in order to get the desired result.
limit(sortByMaxima(averageAbove(stats.timers.*.median, X)), N)
Starting the the averageAbove as the base.
The next thing you want to do is get all the metrics in order, "top-to-bottom" by using sortByMAxima.
Then you can limit the results that are rendered with the limit function.
You might not be rending the legend if you have too many metrics for the size of the graph. You can do 3 things.
- Make the graph larger
- Reduce the number of metrics using limit
- Force the legend to be displayed via hideLegend
