This fixes an issue where systems with many CPU cores
run out of usable graph colors and canvas area.
It also unifies the canvas size for all graphs.
Discussion: https://community.ipfire.org/t/cpu-freq-graph-not-working-with-i5-1235u/9396
Fixes: #12890

I think you could have written this slightly shorter by taking the modulus of j like so: $j = $i % 20;
But since this is not changing the behaviour, I am happy to see this merged.
