Delete the previous series

[Umer]

Hey i used your widget to create line series in my Angular Project.
I used the following method to create the dynamic series.

this.chart.addSeries([{

dataSource: this.dataSourceObj,

xName: 'x', width: 2,

yName: 'y' ,

marker:{

visible: true,

height: 10,

width: 10

}

}]);

My requirement is to show the series of the selected user, but after selecting the first user series displays correctly but when i select the second user instead of showing me the 2nd user series only the chart shows the both user series. I want to delete the series of the previous user or any user's series before rendering the series of the current user how can i do that?
