[VectorLine] How can I control the closeness of two consequtive points when drawing a line

In my project, I am using VectorLine class to draw graphs on the screen. The data is very dense (sampling rate 20Hz). Therefore, I want to be able to control how far apart the two points can be on the x-axis. So far I am not sure if VectorLine allows that to happen. Here is a snapshot of how close these points are (I would want them to be a lot closer):

Here is a snapshot of how I am drawing this:

Code (CSharp):

1. public VectorLine (string name, List<Vector2> points, Texture texture, float width, LineType lineType, Joins joins);
2.  
3. public void setLine()
4.     {
5.         int i = 0;
6.         foreach (SignalGraphData block in blocks)
7.         {
8.             y1.Add(new VectorLine("signalX" + i, block.y1, thickness, LineType.Continuous, Joins.Weld));
9.             y1[i].endCap = "Arrow";
10.             y1[i].color = xColor;
11.             y1[i].drawTransform = this.transform;
12.             y1[i].rectTransform.localPosition = new Vector3(y1[i].rectTransform.localPosition.x, y1[i].rectTransform.localPosition.y - 7f, 0);
13.             //Debug.Log (y1 [i].rectTransform.localPosition.x + "  " + y1 [i].rectTransform.localPosition.y);
14.             y2.Add(new VectorLine("signalY" + i, block.y2, thickness, LineType.Continuous, Joins.Weld));
15.             y2[i].endCap = "Arrow";
16.             y2[i].color = yColor;
17.             y2[i].drawTransform = this.transform;
18.             y2[i].rectTransform.localPosition = new Vector3(y2[i].rectTransform.localPosition.x, y2[i].rectTransform.localPosition.y - 7f, 0);
19.  
20.             y3.Add(new VectorLine("signalZ" + i, block.y3, thickness, LineType.Continuous, Joins.Weld));
21.             y3[i].endCap = "Arrow";
22.             y3[i].color = zColor;
23.             y3[i].drawTransform = this.transform;
24.             y3[i].rectTransform.localPosition = new Vector3(y3[i].rectTransform.localPosition.x, y3[i].rectTransform.localPosition.y - 7f, 0);
25.             i++;
26.         }
27.  
28.         //Debug.Log ("POSITION: " + blocks [blocks.Count - 1].y3 [y3.Count - 1].rectTransform.localPosition.x);
29.  
30.  
31.  
32.     }
