We are using an older version of Aspose.Chart, version 18.104.22.168 (2006.12.13) with Visual Studio 2010. We create a gantt chart from scratch and display it for the user in an ASP.NET website. Our current issue is that the data labels print the ending date for both the label at the beginning and end of the bar. So if the data row being graphed is from 7/1/2014 to 7/7/2014, it prints the 7/7/2014 as the beginning and ending data label. The bar prints correctly, its just the beginning label that is wrong. I don’t see where I can set two different data labels for the same bar.
Aspose.Chart was discontinued around five years back and we do not have any support material related to Aspose.Chart now.
However, Aspose.Cells for .NET allows you to create charts. Please check Working with Charts section in the documentation for more details and feel free to contact us in case you have further comments or questions.
