But why? The dashboard you're making isn't for your car or private jet, it's for your business. Dials don't mean squat, other than being useless eye candy. They take up a lot of room to show a single value, and they don't show trends, just a solitary value. They also make it very difficult to compare value with each other.
To show the value with its trend, use a line chart showing the last several periods leading up to the current value.
To show a single value in a small amount of space, in such a way that makes comparison between several such values side-by-side, use bullet charts. I've just written a tutorial showing a quick and easy way to do Bullet Charts in Excel.
