I have implemented graphs and drawn series using the following code
DotNet.Highcharts.HighCharts chart=new Highcharts.HighCharts("chart");
chart.SetSeries(new[] {new Series{Name="one",Data =new Data(new Object[,]{{0,0},{10,0.6},{20,0.5}})}});
chart.SetSeries(new[] {new Series{Name="two",Data =new Data(new Object[,]{{0,0},{12,0.8},{29,0.35}})}});
Now i at run time i want to add points when a button is clicked and the series name is choosen from the dropdown and values of x and y axis are given in textboxes. can'nt figure it out how to add points when addpoint button is clicked by the user.
