How to use connection lines in the Gantt Chart?
A Gantt chart is a graphical representation of the duration of tasks against the progression of time. This chart is excellent for planning the use of resources, and data can be plotted using a date-time scale or a numerical scale.
We have the direct support to connect the Gantt chart points using the property "RelatedPoints" and various customizing options are also available. Here is the sample code to do this.
C#
//Indicates the connection lines between the points
int[] ptIndices1 = new int[] { 1 };
this.ChartWebControl1.Series[1].Styles[5].RelatedPoints.Points = ptIndices1;
//Customizing options for the lines.
this.ChartWebControl1.Series[1].Styles[5].RelatedPoints.Color = Color.Red;
this.ChartWebControl1.Series[1].Styles[5].RelatedPoints.Alignment = System.Drawing.Drawing2D.PenAlignment.Center;
this.ChartWebControl1.Series[1].Styles[5].RelatedPoints.DashStyle = System.Drawing.Drawing2D.DashStyle.Solid;
this.ChartWebControl1.Series[1].Styles[5].RelatedPoints.Width = 2f;
