The rendering in the Designer's middle panel is in Java2D.

External renderings can be created in any combination of the image formats shown: SVG, PNG, and JPEG.

The name(s) of the rendered image files are initially derived from the top line of the Bullet Graph's label; this can be overridden in the text field in this tab. The image files are placed in the identified directory (or folder, if that works for you) in the file system; this can be changed via the Location: button.

Rendering the image files into the file system permits them to be picked up and displayed by the end-point dashboard, or however else is useful.

Work on the image rendering is continuing—as of this writing the image quality is good, with some wrinkles to be ironed out.

See Renderings for the rendered image files.
