Is it possible to save charts as PNG images automatically to a temp dir?

And or render the chart as a temp file and control the filename?

The SharePoint site would not be public.

We simply need to generate named png images of the nevron charts that we have created in SharePoint to a temp folder.

We would then use a script to push the png images to our mobile site.

This look to be possible with the .net version but not with the SharePoint version of nevron?
