Hi,
i wonder if there is a way to hide some marker in a chart.
When i got a dataset with 50 rows and i am showing them all in a
single chart, i would get 50 marker. Is there a way to set a
interval or a maximum number?
Cheers,
Dennis

Hi,
i found a solution
function beforeDrawMarker( marker, dph, icsc )
{
if (dph.getIndex() % 10 == 0) {
marker.setVisible(true);
} else {
marker.setVisible(false);
}
}
The only thing is, markers in the legend/caption become invisible, too.
But i guess there is a way to find out if its a marker in the caption or not.

Dennis,
this is because your script gets called everytime a marker is generated
in the series and the legend try this:
arr = false
function beforeDrawMarker( marker, dph, icsc )
{
if (dph.getIndex() % 10 == 0) {
marker.setVisible(true);
} else {
if( !arr ){
marker.setVisible(false);
}else{
marker.setVisible(true);
}
}
}
function beforeDrawLegendItem( lerh, bounds, icsc )
{
arr = true;
}
