Dial chart dynamic color range

Question

Hi
I am trying to dynamically change range of the scalebar color.
I see that I can give Apex a low and high value exactly for this reason.
    Invalid Dial chart query, use the following syntax:
     SELECT VALUE, MAX [, LOW, HIGH] VALUE FROM ...
    VALUE      Numeric column that defines dial value.
    MAX      Numeric column that defines Maximum dial value.
    LOW (optional)      Numeric column that defines the low value of a range to display on the dial. If this value is defined, a HIGH value is required.
    HIGH (optional)      Numeric column that defines the high value of a range to display on the dial. If this value is defined, a LOW value is required.
    This query should return one row.I would hope for Apex to use those value in the #SCALE_DATA# in the Chart XML.
<axis start_angle="90" sweep_angle="180" >
#SCALE_DATA#
        <labels enabled="true" align="Inside" text_align="Near" rotation="0" >
              <format><![CDATA[{%Value}{numDecimals:0,decimalSeparator:\,,thousandsSeparator: }%]]></format>
          <font family="Tahoma" size="10" color="#000000" />
        </labels>
</axis>But it does not seems to work.
I only need to add those lines
<scale_bar enabled="false" />
<color_ranges>
   <color_range start="0" end="25" color="Red" />
   <color_range start="25" end="90" color="Green" />
   <color_range start="90" end="100" color="Red" />
</color_ranges>25 being the #LOW# value and 90 the #HIGH# value.
I do not want to use custom XML everywhere.
ANy iadea if I can modify the default XML or modify the behavior of the #SCALE_DATA# ?
Thanks a lot

Hello,
What do you mean by maximum value?
The 10 in the query is to figure out values other than the dial itself there is not a graphical component that represents that number.
The high line usually is used historical maximum value. Do you want to change the color of the dial when it hits 10?
