What is the use of LineCap and LineJoin properties for line series?

The LineCap property specifies the type of line cap that should be applied to the line segments in the line series. The possible values of this property are Butt, Round, and Square.

The property, LineJoin, specifies the type of line that should be applied when two lines intersect. The possible values of this property are Miter, Round, and Bevel.

CSHTML

@(Html.EJ().Chart("container")    
    .PrimaryXAxis(axis=>axis.ValueType(AxisValueType.Category))
    .CommonSeriesOptions(options=>
        options.Type(SeriesType.Line)
        .LineJoin(ChartLineJoin.Bevel)
        .LineCap(ChartLineCap.Square))
)
