I suppose that this issue is related to the fact that domain contains only string values.

I suppose that you should update this condition something like this:

if (role !== 'category') {
    domain.push(v)
}

Added category check in latest commit.

Next steps:

• [x] Handle categorical stops (strings) in addition to numeric stops for color ramps

[ryanbaumann]

Categorical stops shipped in the latest release
