Hi team ,

i got COLUMN_3_D_CLUSTERED chart type.
Is someother name given to it?

Looking forward for your reply.

ChartType.COLUMN is actually a clustered column chart, so please use it for your needs.

Thanks Shakeel. it worked for me .
my next question is
how i can remove the null values from the chart ?
in my previous sheet i requested :-
how i can add data labels to the chart

Looking forward for your reply.

Hi,
How i can add data labeles to charts?
i tried doing this

DataLabels dataLabels = chart.getNSeries().get(0).getDataLabels();
dataLabels.setShowPercentage(true);
but it gives exception as array index oout of bound exception because chart.getNSeries() is [].

Can you please check this issue?

Thanks,
Nidhi

Hi team,

Thank you for the quick response.
Atcually i already tried this piece of code .
DataLabels dataLabels = chart.getNSeries().get(0).getDataLabels();
but it gives exception as array index oout of bound exception because chart.getNSeries() is []. Can you please check this issue?

Looking forward for your reply.

Please check how many series are present inside your chart. It seems, there is no series inside your chart.

Print the count of series like this

Java

//Check the number of series inside the chart
System.out.println("Number of Series: " + ch.getNSeries().getCount());
