plot - How to specify the value where colours change in the key? (openair, R) -


i plotting pollution data using openair in r, , have multiple plots same axis on colour scheme.

because there few high peaks in data, it's throwing rest of colour chart off of key 1 colour, , rest of colour spectrum squashed down lowest values.

easiest see picture - example of 2 of axes here

enter image description here

how can change colour spectrum more evenly spaced out? if try force through limits = c(0, 1.0), turns whole plot 1 colour.

i appreciate help! :)
