CircularHeatChart - Global Maximum and Minimum

[NRN13]

The current CircularHeatChart uses color scales on a category basis (i.e. max and min of each layer get the lightest and darkest color for that layer).
how can i alter the code to allow for a absolute maximum and a minimum such that the absolute minimum gets the lightest color and the absolute maximum get the darkest.
Thank you in advance for your help!!

1.Enable Code of Line 307:
color.domain([d.minPrice, d.maxPrice]);
to determine the minimum and maximum values.

2.And Enable code of Line 247, and disable code of Line 248:
color = d3.scale.linear().range(['#c7f918', '#4a5a11']),
// color = d3.scale.category20();
to set customized threshold color, instead of using a category basis color.

Then you could get the absolute minimum gets the lightest color and the maximum gets the darkest.

My apologies for leaving that part out. I had already changed those two codes you suggested in order to get the same colour group.

as you can see they are the same shade, however i want 99.3 to be alot lighter, even though it is the smallest number in it's layer and 97.1 is the absolute min so it should be alot darker. I hope this makes my question more clear.

Thank you in advance
