Can we make the base of the exponent function a variable?

[nickidlugash]

What is the reason for the base of the exponent function being 1.75, instead of a variable? Would it make sense for it to be a parameter that the designer can change? If not, is there a way to make this constant explicit so the designer will be able to understand the function better?

From the style declaration:

function exponential(z_base, val, slope, min, max) {
    z_base = +z_base || 0;
    val = +val || 0;
    slope = +slope || 0;
    min = +min || 0;
    max = +max || Infinity;
    return function(z) {
        return Math.min(Math.max(min, val + Math.pow(1.75, (z - z_base)) * slope), max);
    };
}

Yes absolutely.

Agreed.
