Range of Analysis

Hi,

Fairly new to Ladybug, but seems amazing :) !

Just wondering - is there a way to change the upper and lower bounds of the visibility analysis? If I don't have any values between, say 50-100%, it would be useful to compress the colour coding if the analysis to between 0-50% to get more variation...

changing upper / lower bounds of the legend parameter didn't seem to do it ....

many thanks,

Peter
