How to add dynamically New Value axis and graph in Angular 6 by using Amchart 3

[pankajd1990]

var valueAxis = new AmCharts.ValueAxis();
valueAxis.id = "p"+this.graphName.length,
valueAxis.title= "",
valueAxis.titleColor= "black",
valueAxis.color = "black",
valueAxis.position= "left",
valueAxis.axisThickness= 2;
// this.intigratedChartInstance.addValueAxis(valueAxis);
this.intiChartInstance.addValueAxis(valueAxis);

var amGraph:any = this.amChart.AmGraph();
amGraph.title= this.graphName[this.graphName.length - 1].key,
amGraph.id= "g"+this.graphName.length,
amGraph.valueField= this.graphName[this.graphName.length - 1].key,
amGraph.valueAxis= "p"+this.graphName.length,
// color: "white",
amGraph.type= "smoothedLine",
amGraph.lineThickness= 2.5,
amGraph.forceGap= true,
amGraph.bullet= "none",
amGraph.minDistance=2,
amGraph.bulletSize= 1,
amGraph.ballonColor= "blue",
amGraph.lineColor= "red",
amGraph.useDataSetColors= false,
amGraph.bulletBorderThickness=1,
amGraph.bulletBorderAlpha=1;
this.intigratedChartInstance.addGraph(amGraph);
