Custom dataset colors

By default, the dataset colors will be automatically set in order based on the onyx quantitative colors. If you want to set a specific color for a dataset, you can use the getDatasetColors utility.

For example to use the primary color for a line chart:

const chartData: ChartData<"line"> = {
  labels: ["A", "B", "C"],
  datasets: [
    {
      label: "Dataset A",
      data: [1, 2, 3],
      ...getDatasetColors("primary"),
    },
  ],
};
