I am using aspose slides for java in order to generate a powerpoint from an excel sheet .
I need to modify the displayed categories ( rows ) of an histogram according to some criteria .
Below a histogram that I would to modify :
Sans titre1.png (2.5 KB)
I set the values of the categories I want to hide to “null” , the cells became empty but I still have a white space in my chart . I tried chart.getChartData().getCategories().remove(chart.getChartData().getCategories().get_Item(4)) but it doesn’t work .
In other words , I want to hide empty cells from the chart .
Is there any method to do this by using Aspose slides for java ?
Just a detail : I’m using a trial version of aspose.slides in order to test its functionlities and i’m planning to purchase the product soon .
Thank you .
