Suggestion: Chart point color based on value

 

I am trying to figure an easy way to implement a UI feature in bar charts that would paint the bar not in one color but with a varying color depending on its value.  Or maybe this couls be an easy suggestion?!?

 

For example: assuming our bars would go from 0 to 100 in value. Well, in this example, a bar of value 10 would start red and finish with a lighter red.  A bar of value 50 would start red and finish yellow.  A bar of value 100 would start red and finish green.  Of cource, steps would be defineable.

 

This would provide immediate visible feedback for example on failure or success of each points or elements in the chart.

 

Here is a demo of what I am saying:

 

 

Comments and suggestions are welcomed!

 

Thanks in advance
