Data Label is formatted to Percentage by Default. Unable to format it to Number

Hi,

I am using Aspose Slides for Java. Version: 17.8

I have a chart which has data labels.
One of the data series is plotted on Secondary Axis as Line With Markers Chart.
Data Points in the series are of decimal type.
I am using the below snippet to format Data labels.

chart.getChartData().getSeries().get_Item(2).getLabels().getDefaultDataLabelFormat()
            .setNumberFormat("0.00");

It is formatting to Percentage. I want it formatted as Number.

Please let me know if I am missing anything or if there is an alternative way.

@gagangupt16,

I have observed your comments. I have codes snippet with you. This will help you to achieve your requirements.

IChart chart = pres.getSlides().get_Item(0).getShapes().addChart(ChartType.ClusteredColumn, 50, 50, 600, 400, true);
IChartSeriesCollection series = chart.getChartData().getSeries();
IDataLabel label = series.get_Item(0).getLabels().get_Item(0);
label.getDataLabelFormat().setShowValue(true);
msAssert.areEqual(label.getDataLabelFormat().getNumberFormat(), “”);
label.getDataLabelFormat().setNumberFormat(“0.00”);
msAssert.areEqual(label.getDataLabelFormat().getNumberFormat(), “0.00”);

Thanks Adnan but the above snippet is not still able to format beyond a certain number of labels.

Also, in your snippet, you have created chart. In my scenario, I already have an existing PPT and I need to modify that chart.
