Creating a Color Scale

The ColorScale class creates a custom color scale given an array of data. In this example, we are providing an array of 2 values, but the array of data can be of any length (it extracts the values from all available data points).

var data = [
  {value: 20},
  {value: 640}
];

var bottom = new d3plus.ColorScale()
  .data(data)
  .render();
