Using Aspose.Net 220.127.116.11
If I put a chart on the same sheet as the data it references its cell references are updated as I insert/delete rows on the sheet. If I put the same chart on a different worksheet (or use a chart sheet) the references aren't updated. The insertrows and deleterows calls have true specified for the updatereference parameter and non-chart references on the sheets are updating correctly.
Can you have a look at this?
