First of all I would like to thank you for the great support during the last few weeks. With your quick replays to all kind of questions I was able to nearly complete my current project.
Finally, there is only one kind of chart left to be implemented. Thereby the chart is not the real problem (it consists only of simple lines). The main issue with this kind of report is the need of additional controls indicating specific points in time. Please take a look at the attached file where you can find a small sample report page. I know the size of the diagram and I know the first and the last value of the category axis. It is possible to add vertical lines and textboxes in relation to a given category value to a chart or at least to an excel sheet using aspose? I would appreciate any kind of help to solve this final problem.
Thanks in advance
