I'm trying to simulate a status bar with simple horizontal HTML bar chart. The status bar that I need is simply a background horizontal bar with red color filled with percentage of completion represented as green color on that red bar. I thought of giving 100% for red bar as one parameter and whatever the percentage green bar as another parameters to HTML bar chart to show the status bar, but the horizontal bar takes link, name and count as parameteters. any ideas to produce status bar with simple horizontal HTML bar chart is appreciated.

thanks,
