When setting a gauge to 0, the value is completely elided. This was caused by #100. There was a code review comment to replace some string manipulation with

return rtrim(rtrim(number_format($value, 5, '.', ''), "0"), ".");

is was instead replaced with

return rtrim(trim(number_format($value, 5, '.', ''), "0"), ".");

which transforms a zero to an empty string

Same problem for me.
