Frappe Charts v10


i am trying to create a chart in version 10 but its not working, same code working in v9,v11 etc but not working in v10,

i tried many syntax but no luck, below is the code i tried

const graph = new frappeChart.Chart({
 				parent: "#chart",
 				data: chart_data,
 				type: 'bar'

setTimeout(function () {graph.refresh()}, 1);

error :

TypeError: Cannot read property 'type' of undefined

also below is the code of production_analytics.js

this.chart = new frappeChart.Chart(".chart", {
			data: chart_data,
			type: 'line'

Solved by using graph.draw instead of graph.refresh

setTimeout(function () {graph.draw()}, 1);
