Feature request - Exclude outliers

[lkblkb]

This is a fantastic tool, however the graph in 'actual' mode is not that useful due to some extreme outliers:

If it's possible, an option (or simply default) to exclude outliers would make this a lot more useful :) E.g. exclude gas prices >500.

Also exlude gas <50 or some amount below the average.

Often the average is affected by very low or high gas fees (e.g. 6 gwei, 10 gwei).
