Dc.js Change Default Color For Undefined Data In Choropleth Map

I'm using dc.js for a choropleth map with dc.geoChoroplethChart(). Previously with colorCalculator(), I can set the default color for null data. chart.colors(colorScale) .colo

Solution 1:

Deprecating colorCalculator function was a mistake and the warning will be removed soon.

I don't like the way the function was implemented, and at the time I thought that scales can do everything that a function can do, but it is simply easier to write a function for this kind of thing.

Sometimes a special case is the best way to deal with an exception to the rule!

Alternately, if you are using a continuous or ordinal color scale, you may be able to use .unknown() which is a cleaner solution.
