As you can see, I have only two very high bars that make everything else indiscernible.
For various reasons I don't like the idea to use a log axis just for these two values.
Is there a way to truncate in some way the tall bars, so that they have a manageable height? In contrast to just tweak the data to have a smaller bar, I'm looking for something that visually hints at this truncation.
ymax=...
where...
is an appropriate value?
