Suggestion: Consider option to support a max value size

[jadrake75]

I am passing in an array of values that range from 0.0 to 1.0 and represent the percentage of memory used in a small monitoring dashboard. It would be nice if we could set an option to set the maximum value (in my case 1.0) so that the values are rendered within that range and appear as a percentage fill rather than only fluctuating based on value
