Generating and Saving ZedGraph plots without showing on forms

Is it possible to plot data on to a ZedGraph graph and save it as a file without showing / generating a graph that is visible to the user? I'm looking to process a lot of datasets and generate a graph and saving it to a file for viewing outside of the application.

If this can't be done, would it be possible show the graph on a hidden/minimized form, save the graph, close the window, and repeat for each graph?

Here is a code snippet to create and save the Bitmaps without any WinForms infrastructure necessary:

var zedGraph = new ZedGraphControl();

// configure ZedGraphControl here

using (var g = zedGraph.CreateGraphics())
{
    zedGraph.MasterPane.ReSize(g, new RectangleF(0, 0, widthPx, heightPx));
}
zedGraph.MasterPane.GetImage().Save(Path.Combine(destinationDir, "test.bmp"));

This should even be able to run as service without any desktop. The only downside is that you need to reference System.Windows.Forms and System.Drawing to use it.
