BSP Graphics Extension (MTA)

Question

Dear All,
I am trying to generate an MTA using BSP graphics extension. I have managed to get the structure of the graphic:
<Defaults>
<ChartType>MTA</ChartType>
<FontFamily>Arial</FontFamily>
</Defaults>
However, I am having trouble placing the values or points on the chart.
As far as I understand, I can use "Series" to generate points on bar charts or line charts,
   <SimpleChartData>
        <Categories>
          <C>Category 1</C>
          <C>Category 2</C>
          <C>Category 3</C>
          <C>Category 4</C>
          <C>Category 5</C>
        </Categories>
        <Series>
          <S label="17.55%">17.55</S>
          <S label="17.10%">17.10</S>
          <S label="8.70%">8.7</S>
          <S label="8.25%">8.25</S>
          <S label="6.87%">6.87</S>
        </Series>
      </SimpleChartData>
but this won't work for the MTA.
I have defined the timeaxis
<TimeAxis id="TimeAxis1">
   <Visibility>true</Visibility>
   <Extension></Extension>
   <Minimum>20060101</Minimum>
   <MinimumAutomatic>true</MinimumAutomatic>
   <Maximum>20080101</Maximum>
   <MaximumAutomatic>true</MaximumAutomatic>
   <Position>Secondary</Position>
</TimeAxis>
<TimeAxis id="TimeAxis2">
   <Visibility>true</Visibility>
   <Extension></Extension>
   <Minimum>20000101</Minimum>
   <MinimumAutomatic>true</MinimumAutomatic>
   <Maximum>20080101</Maximum>
   <MaximumAutomatic>true</MaximumAutomatic>
   <Position>Primary</Position>
</TimeAxis>
so my guess is it should go something like
   <SimpleChartData>
        <Categories>
          <C>Category 1</C>
          <C>Category 2</C>
          <C>Category 3</C>
          <C>Category 4</C>
          <C>Category 5</C>
        </Categories>
        <Series>
          <S label="20050101">20050101</S>
          <S label="20050601">20050601</S>
          <S label="20050601">20050601</S>
          <S label="20050701">20050701</S>
          <S label="20050701">20050701</S>
        </Series>
      </SimpleChartData>
This won't work.
I have looked all over the web, but there seems to be little to no documentation to the BSP graphics extension, and especially to time axis. I have also found a lot of examples of normal charts with time axis, but none which show a simple defition of fixed values.
The chart is merely for show-case use, therefore using fixed values is no problem.
If anyone has an idea as to what might work, please help
Thanks

i have used a model class.
data: model type ref to ZCL_GRAPH_CPH_MODEL . " this class implements IF_GRAPH_DATA_MODEL interface
  create object model.
<graphics:chart width               = "400"
                          height              = "300"
                          igs_rfc_destination = "IGS_RFC_DEST" >
            <graphics:data model="<%= model %>" />
            <graphics:custom>
              <graphics:nativexml>
                <?xml version="1.0" encoding="utf-8"?>
                <SAPChartCustomizing version="1.1">
                 <GlobalSettings>
in the method (IF_GRAPH_DATA_MODEL~GET_DATA_XML) i populate the values like this.
