Styling background with ChartJs and React

I want to create a Line chart in React by using the chartJS library (‘react-chartjs-2’)

This is what I want to achieve, like background with some opacity belowe the line:

Code:

import React from 'react';
import {
  Chart as ChartJS,
  CategoryScale,
  LinearScale,
  PointElement,
  LineElement,
  Title,
  Tooltip,
  Legend,
} from 'chart.js';
import { Line } from 'react-chartjs-2';
import faker from 'faker';

ChartJS.register(
  CategoryScale,
  LinearScale,
  PointElement,
  LineElement,
  Title,
  Tooltip,
  Legend
);

export const options = {
  responsive: true,
  plugins: {
    legend: {
      position: 'top' as const,
    },
    title: {
      display: true,
      text: 'Chart.js Line Chart',
    },
  },
};

const labels = ['January', 'February', 'March', 'April', 'May', 'June', 'July'];

export const data = {
  labels,
  datasets: [
    {
      label: 'Dataset 1',
      data: labels.map(() => faker.datatype.number({ min: -1000, max: 1000 })),
      borderColor: 'rgb(255, 99, 132)',
      backgroundColor: '#000000',
      fill: {
        target: 'origin',
        above: 'rgb(255, 0, 0)',   // Area will be red above the origin
        below: '#000000'    // And blue below the origin
      }
    },
    {
      label: 'Dataset 2',
      data: labels.map(() => faker.datatype.number({ min: -1000, max: 1000 })),
      borderColor: 'rgb(53, 162, 235)',
      backgroundColor: 'rgba(53, 162, 235, 0.5)',
    },
  ],
};

export function App() {
  return <Line options={options} data={data} />;
}

Is it possible that this library doesn’t support it?

Maybe is there something that I should change?

Thanks a lot for any help

Best!
