Color gradient for Visual Analytics 8.2 heat map


Hi all


I have been working with correlation matrices off and on, without thinking about this aspect too much ( one indication that perhaps it is not very important), but I noticed the following ,and wondered if there is a way to change it ?


- The gradient options provide for a starting color and an ending color (I would assume it is from lowest to highest like we generally perceive measures)


- However, the actual gradient is shown based on strength - weak to strong - therefore for -0.95 (strong negative) and 0.95 (strong positive), the same green color is depicted


- While I still find it useful (it helps in basic inference of variable relationships ), wouldnt there be value in changing this to a three color gradient - something like red - white - green, so that 

         * anything close to 0 (weak or almost no correlation) is white 

         * large positive correlation values are higher on the green scale

          * large negative values are higher on the red scale




Perhaps convention dictates the current gradient, but I thought I will put this as a suggestion anyways. I understand there will be some internal feature request mechanism at SAS so perhaps this has been dealt with already.

Try using ‘rules’. Didn’t try it myself but in the TreeMap object, I could over ruled that gradient, using ‘rules’. Pls let me know if it worked
