Criterion: Is it possible to alter Benchark graph?

Question

I just started using the excellent criterion package and I was wondering if it's possible to alter the graph. For example I would need to

• normalize result within a group so that the longest result of a group take the full width of the graph (whatever the time spent in other groups)

• to change the order of the bars in the graph to be able to have a standard bar charts where instead of having cluster of bar of the same colours, you could have cluster of bars using all the different colours.
