BIP Gauge Thresholds Configuration in RTF template

Hi,

is there a way to configure thresholds on gauge in an RTF template?

My code is this and I need to change the color from red to yellow and green

<Gaugeset gaugeType="DIAL" maxValue="100" minValue="-100">

<Gauge>

  <LegendArea visible="true"/>

  <Indicator type="IT_NEEDLE"/>

</Gauge>

<LocalGridData colCount="1" rowCount="1">

<RowLabels>

 <Label></Label>

</RowLabels>

<ColLabels>

  <Label></Label>

</ColLabels>

<DataValues><RowData><Cell><xsl:value-of select="sum(//QTA_RIGA)"/></Cell></RowData></DataValues>

</LocalGridData>

</Gaugeset>

Thank you

Valeria
