10g Graphs - How to customize the default color of a Bar Graph

Question

Hi,
I've posted this thread in Reports section, have received no reply yet. Maybe no one has ever tried this before!!
I am porting a couple of 6i OGD's to 10g graphics.
Basically I am invoking reports from a form. The reports contains embedded Graph.
Here comes the tricky part.
I have a couple of Graphs in 6i that display each bar of a bar graph in different color.
Example:
Value       Bar Color
Critical     Red
Major       Orange
Minor       Yellow
None       GrayQ) I want to know how to set the color of each bar of a bar graph based on the value it takes. i,e If it's critical the bar should be displayed in red. If it's major, the bar should be displayed in orange.
I added conditional formatting in 10g Graph, and this is the trigger that was created.
function CT_1FormatTrigger return boolean is
begin
  -- Automatically Generated from Reports Builder.
  if (:f19 > -1)
  then
    srw.set_foreground_border_color('yellow');
    srw.set_border_pattern('solid');
    srw.set_foreground_fill_color('yellow');
    srw.set_fill_pattern('solid');
  end if;
  -- Automatically Generated from Reports Builder.
  if (:f20 > -1)
  then
    srw.set_foreground_border_color('red');
    srw.set_border_pattern('solid');
    srw.set_foreground_fill_color('red');
    srw.set_fill_pattern('solid');
  end if;
  return (TRUE);
end;When I try to invoke the above report from the form, I get the error: FRM-41214: Unable to run report.
If I remove conditional formatting, I am able to invoke the report from the form with the default color in the embedded graph.
Hopefully someone has ideas on this!
Thanks

Why don't you use the build-in charting capability of reports 10g instead? There is FormsGraph.jar implementation for forms but that might not have the flexibility of what 6i graphs has/had and not "officially" supported - not like the reports 10g charting capability (which is built in and can be customized by editing the related xml files (if necessary). Note: FormsGraph.jar has it's own limitations
