The use of common series options in ASP.NET MVC Chart.

The CommonSeriesOptions property provides options to customize marker, data label, and other properties of all the series in the ASP.NET MVC Chart. Except the Points property, all the other properties in the series are customizable by using the CommonSeriesOptions property.

For example, changing the marker shape in the CommonSeriesOptions changes the marker shape of all the series. To customize marker and other properties for a specific series, values should be provided to the properties of that specific series in series collection. In general, values provided to the series in series collection overrides the values provided through the CommonSeriesOptions.

@(Html.EJ().Chart("chart")
 .CommonSeriesOptions(options=>
     options.Marker(m=>m.Visible(true)))
 .Series(s =>
 {
     s.Points(p => {
         p.X("1").Y(35).Add();
         p.X("2").Y(26).Add();
         p.X("3").Y(51).Add();
         p.X("4").Y(69).Add();
       })
      .Marker(m =>
         m.Fill("blue").Size(sz => sz.Width(10).Height(10))
      )
      .Add();
    s.Points(p =>
     {
         p.X("1").Y(72).Add();
         p.X("2").Y(29).Add();
         p.X("3").Y(48).Add();
         p.X("4").Y(39).Add();
     })
     .Add();
    s.Points(p =>
    {
        p.X("1").Y(52).Add();
        p.X("2").Y(58).Add();
        p.X("3").Y(32).Add();
        p.X("4").Y(11).Add();
    })
     .Add();
 })
  )
