Show negative bubbles in Bubble chart

Am using Aspose.Slides for .NET 20.7.0 and filling a bubble chart in my slide. Before that am clearing all my series and categories but am not getting any option for enabling the “Show Negative Bubbles” in bubble chart series .

How can I make “Show negative bubbles=true”

I request you to please try using latest Aspose.Slides for .NET 20.8 on your end. In case there is still an issue then please share the working sample code along with source presentation, generated presentation and desired output presentation with us.
