Heatmap colors are wrong and some options are not working

[beldogueto]

Hello! Many thanks again for this amazing project!

Description

Heatmap colors are working on a wrong way.
Ex: if I set blue-white-red scale, it should be something like this:

From the min to the max value

What I have when I set "from" and "to" options are negative values behaving different from positive values.

• Negative values follows this min-max color gradient (ex: MIN values are strong blue and MAX values white/weak blue).
• Positive values are having the colors inverted and are plot as max-min gradient (ex: MAX values are strong blue and MIN values white/weak blue).

I understand this behavior could also be an option, but negative and positive values should follow the same color gradient when placed together (from min to max).

Also the following options does not look like having any impact on the headmap and maybe are not working:
colorScale.inverse
colorScale.min
colorScale.max
reverseNegativeShade
distributed

Expected Behavior

To follow a linear color gradient, from min to max values, like this:

Actual Behavior

Negative values are following min-to-max color gradient, positive colors are doing max-to-min color gradient:

Giving the post a boost. I imagine this could be important as heatmaps rely on color gradients and can have values ​​below and above zero in the same graph.
