OxyPlot on Linux (no GUI)

I have a C# program running on linux without any kind of graphical interface and I'm trying to create graphs dynamically and save them to images. As I understand, all platform-specific libraries are focused on use with a GUI (WinForms, WPF, GTK#...) but I would expect to have at least a PngExporter implementation using System.Drawing (same as zedgraph does), so no graphical libraries would be needed at all. Is this capability already supported?

Thank you very much

I think is should be possible to use the PngExporter in the Gtk# implementation! I have not tried this on linux myself yet, so it will be interesting to hear your experiences!
