SharpPlot.DrawTriangle Method

Create a triangle chart (relative proportions of exactly 3 series):

Example

samples = new int[,] {{3,4,4},{4,2,2},{3,4,2},{4,3,1}};

sp.SetMargins(12,6,0,0);
sp.TriangleStyle = TriangleStyles.GridLines|TriangleStyles.Markers;
sp.SetMarkers(Marker.Bullet);

sp.XCaption = "Na";
sp.YCaption = "K";
sp.ZCaption = "Ca";

sp.DrawTriangle(samples);

The short tutorial shows a few of the possibilities and some sample code.

Overloads

• public void DrawTriangle(int[][] data);
• public void DrawTriangle(double[][] data);
• public void DrawTriangle(int[,] data);
• public void DrawTriangle(double[,] data);
• public void DrawTriangle(int[] s1,int[] s2,int[] s3);
• public void DrawTriangle(double[] s1,double[] s2,double[] s3);

Description

This chart is typically used to profile a series of samples of the 3 key constituents of some raw material or industrial process. The data may be shown as proportions or percentages, but it will always be normalised into the range 0-1. If only 2 sets of samples are given, the third set is deduced by subtraction from 1 or 100 as appropriate.

Various styles can be used to vary the appearance of the chart, but the axis range and tick spacing are pre-determined here.
