Bulb Colorrange/color Transparency

[sagitarre]

Hi,

 

Can the bulb gauge have a color range be transparent? I want the bulb to be transparent if the value is '0' or '1'. I've tried the following configuration without luck. I feel like my understanding of how to use "alpha" in this specific case is incorrect?

 

<colorRange>

<color minValue='0' maxValue='1' name='Normal' code='52D017' alpha='0' />

<color minValue='1' maxValue='75' name='Warning' code='F6BD0F' alpha='100' />

<color minValue='75' maxValue='100' name='Danger' code='FF654F' alpha='100' />

</colorRange>

 

Thx!
