[Solved]-Chart.js core.js:6162 ERROR Error: "line" is not a registered controller-Chart.js

please upgrade npm package, its worked for me

npm i chart.js@2.9.4

Angular 12 here. Gaurev's answer worked for me. I had to use:

import { Chart, registerables } from 'chart.js';
export class ChartTest {

  constructor() {
    Chart.register(...registerables);
  }

  // methods to actually make the chart per documentation
}

We can do this in three ways

1. By importing:

   import { Chart, registerables } from 'chart.js';
   

   and then register all the coponents

   Chart.register(...registerables);
   

2. finally there is an separate path to do just the above for you, in one line:

   import Chart from 'chart.js/auto';
   

3. By importing and registering the required part as commented by @Tatyana Molchanova

   import { Chart, ChartConfiguration, LineController, LineElement, PointElement, LinearScale, Title} from 'chart.js' 
   

   and then register it in component before instantiating new Chart

   Chart.register(LineController, LineElement, PointElement, LinearScale, Title);
