Not able to show percentage in bar-charts

Hi
I am not able to show Chart labels as percentage in Aspose.Slides
Below is my code:
IDataLabelFormat seriesLabelFormat = barChartSeries.getLabels().getDefaultDataLabelFormat();
seriesLabelFormat.setShowValue(true);
seriesLabelFormat.setShowPercentage(true);
seriesLabelFormat.setNumberFormat(“0%”);
seriesLabelFormat.setNumberFormatLinkedToSource(false); //true or false to this doesn’t make any diff

While i can see the corresponding-fields change on PPT, the chart labels don’t show %. I have attached screenshot of both
Fields changed:

Chart not showing %:

@wishy.em,

I have observed your comments. Can you please visit this documentation article to achieve your requirements and share feedback with us if there is still an issue.

This seems to work. Thank you.
I am curious why doesn’t my above code work even when the fields reflect the changes, the chart doesn’t.
