This is a Progress Bar for showing state. You can show anything with it - use it to show load on your server, or percentage space free on your servers disk drive. You could even incorporate it with some AJAX to retrieve status information from your webserver dynamically, making the Progress Bar realtime. To redraw the progress bar simply call RGraph.Clear() (which clears the canvas) and then call myProgress.Draw() again.
The colours, title and scale are configurable, allowing you to represent a wide range of values.
