You are right about the limited features set of the chart generation
tool.

The customization you are describing would be a nice addition.
Unfortunately, the current chart tool generates the chart based on the
charttype attribute in the XML report. That attribute is set based on
the charttype attribute set in the report specification.

For your customization, we can see two solutions:

1- Add new attributes/elements to the report specification XML format
to set these new chart parameters

2- Develop an interactive tool which would generate the charts based on
parameters.

In either case, you will be interested in Lire::Report(3pm) and
Lire::ReportParser(3pm) which can be used to write your postprocessing
tool.

The current chart generator is implemented in
Lire/ReportParser/PloticusChartWriter.pm 

(the old GD::Graph-based implementation) 
Lire/ReportParser/ChartWriter.pm
