# Gauge chart (Chartist example)

> Four values on a half ring: a total of twice their sum leaves the lower half empty.

`src/main.ts`:

```ts
import 'chartist/styles.css';
import { pieChart } from 'chartist';

pieChart(
  '#chart',
  {
    series: [20, 10, 30, 40]
  },
  {
    donut: true,
    donutWidth: 60,
    startAngle: 270,
    total: 200,
    showLabel: false
  }
);
```

`index.html`:

```html
<!doctype html>
<html>
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <script type="module" src="/src/main.ts"></script>
  </head>
  <body>
    <div id="chart" style="height: 50vh"></div>
  </body>
</html>
```

The same chart with the 1.x classes (`src/main.classic.ts`):

```ts
import 'chartist/styles.css';
import { PieChart } from 'chartist';

new PieChart(
  '#chart',
  {
    series: [20, 10, 30, 40]
  },
  {
    donut: true,
    donutWidth: 60,
    startAngle: 270,
    total: 200,
    showLabel: false
  }
);
```
