I've created an Excel chart within a PowerPoint presentation, and have successfully opened it via the Aspose.Powerpoint and Aspose.Excel APIs. I retrieve the Chart via the DesignCharts collection, and am able to manipulate the NSeries collection. However, a limiting factor seems to be the original Data Range set for the Chart. Is it possible to add a NSeries that is outside of the original Data Range, and have it successfully display on the Chart? I have tried to do so unsuccessfully and, as of yet, I can't seem to find a clear concise answer within previous posts (it seems that some posts suggest that it cannot be done).
