I've got two datasets referring to the same process executed in two different ways. The execution A
is slower than the execution B
with respect to real time, but the two graphs represent the same phenomena..
I can plot the two together as follows:
plot 'A' using 1:2, 'B' using 1:2
But I obtain two graphs with different X scales: A
was slower, so the graph is much.
I can normalize the graph by doing the following:
plot 'A' using ($1 / maxA):2, 'B' using ($1 / maxB):2
Which works perfectly for me. The only problem being the maxA
and maxB
variables. They are trivial to determine (tail -n1 A | cut -f1
and tail -n1 B | cut -f1
respectively), but I was wondering if there's an automated way of doing it.
Thanks in advance for any kind answer.
Update
After I applied the excellent answer from Wrzlprmft, I finally got to the following pattern, which is quite convenient:
max(Source) = system('tail -n ' . Source . '| cut -f1')
A = 'path/to/A'
maxA = max(A)
plot A using ($1 / maxA):2
Another possible improvement could be including a Column
parameter to the max
function, so that we can also tune the param of the -f
flag in cut
.
Update
Changed my mind on acceptance, since the stats
command seems to be better for this purpose.
Thanks everyone.
