Graphical Presentation of Levels

i have just started wpf programming. now, i want to write e program that will take input from a device and will show corresponding input value as visual feedback. i have already taken the input using C# and i need to simulate that. (like water level display. there might be 1 to 20 levels, the display will show a graphical presentation using colored level (similar to audio equalizer) according to that value)

can anyone help?

Thanks.

You might want to start looking at a few WPF samples.

Here's a bar chart sample, that may give you a few ideas.
