find Total markers on line

Hi,
i am looking to find total number of markers on particular line

i tried 2 ways.....but no luck

1)
function afterDataSetFilled( series, dataSet, icsc )
{
if( series.getSeriesIdentifier() == "Series 1" ){
var list = dataSet.getValues();
totalMarkers = list.length;
}
}

2)
function beforeDrawMarker( marker, dph, icsc )
{
if( dph.getSeriesDisplayValue()=="Series 1"){
var list = dph.getSeriesValue();
totalMarkers = list.length;
}

both seems returning totalMarkers as NULL.

how to get total markers of thisp articular series?
Also how can i print any variable values in BIRT script like 'print out' in C ?

Thanks

Hi mh10,

What is the purpose for figuring the number of markers on a series line?

i am looking to highlight start & end marker 
like below script 
 
var markeridx=0; 
var totalMarkers=0; 
 
 
function beforeDrawMarker( marker, dph, icsc ) 
{ 
if( dph.getSeriesDisplayValue()=="Series 1"){ 
marker.setVisible(false); 
 
if( markeridx == 1 ){ 
marker.setFill( ColorDefinitionImpl.RED( ) ); 
marker.setVisible(true); 
} 
 
if( markeridx == (totalMarkers-1)){ 
{ 
marker.setVisible(true); 
marker.setFill( ColorDefinitionImpl.BLUE( ) ); 
} 
 
markeridx++; 
 
} 
 
 
 
Any suggestions?

mh10,

I'll have to look into the issue of obtaining this information in the chart. One way that would definitely work would be to figure how many are in each series before going into the chart and just passing in the variable for your check.
