I'm using WorkBookDesigner of Aspose.Cells to open an embeded OLE object in a powerpoint file, modify the data and then writing the updated file back to the OLE object. That is all working great, but in order to overcome the "Object Changed" message that my customers have rightfull declared unacceptable I'm attempting to fix it with a picture but am finding the Chart.ToImage() function is working poorly. Here is a sample image of what the function is outputting and what it actually looks like.
It's three standard line graphs with the markers turned off for the last series. The first series gets made correctly but the other two have some odd things about them.
The Actuals series gets zero's put in for values that should just be absent.
The Burn series gets zero's put in at the beginning and the line is charted very strangely. It somehow curves despite the fact it's a line graph.
Any help would be appreciated.
