How to draw graph(line graph , spline graph) in unity using.

Hi all, after done lot of r&d on line drawing in unity. I have made a line graph using vectrosity plugin. i made a simple line graph but i want curve in drawing line. Is there any way do to make graph curve line using vectrosity plugin. Following there is code for line drawing. List linePoints; void AddPoints {

 linePoints = new List<Vector2>();
  for (int i=0; i<data.Count; i++) {
    lineCurvePoints.Add(new Vector3(i*50.0f,data[i],0));
 }

} void DrawGraph() { Vector2[] lineVector = linePoints.ToArray(); var line = new VectorLine ("Line",lineVector , lineMaterial, 2.0f, LineType.Continuous); line.Draw (); } Below is graph image which i draw following code. i want to make curve line so it look like good graph
