Here is my code
import {Chart} from 'frappe-charts/dist/frappe-charts.min.cjs'
data = {
labels: ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"],
datasets: [
{ values: [18, 40, 30, 35, 8, 52, 17, -4] }
]
}

const DemoChart=new Chart( "#chart", {
data: data,
type: 'bar',
height: 140,
colors: ['red']
});

export default DemoChart
