I am sorry to hear the provided CL does not fulfill your requirements. We do not explicitly recommend InkScape, it is simply an example. If you have another tool that can generate an image or pdf from an SVG image you can use that instead.
If you need, however a chart that renders and export on the server, you can consider using the RadChart
- the chart can be exported to an image format and then if you want you can use an additional library to convert it to a pdf format. If the RadChart, however, is used inside the RadGrid, RadGrid's export can be used for the purpose.
More information about the pros and cons between RadHtmlChart and RadChart can be found in this
blog post from Marin Bratanov.
