Plugin Bar Gauge Beta, displaying symetric +-values

is it possible to define Base Thresholds value to 0
for symetrically interpretation of real interval from -x to y with 0 as Base value ?

0 value in the middle of bar white, negative values left green, positive values right red color
Woulde be fine with some negative and positive thresholds colored values.

Is it possible to edit this Base Threshold parameter ?
This plugin is native in Grafana integrated. I suppose that the code is compiled from source and therefore it is no possible. Only developers can make some code corrections.

Same problem
