How to create Bar Chart in ASP.NET

public void Page_Load(object sender, EventArgs e) { // Static Chart (with Bar Labels) int[] arrValues1 = { 6, 10, 12, 18, 23, 26, 27, 28, 30, 34, 37, 45, 55 }; string[] arrLabels1 = { "P1", "P2", "P3", "P4", "P5", "P6", "P7", "P8", "P9", "P10", "P11", "P12", "P13" }; myFirstChart.Text = BuildChartHTML(ref arrValues1, ref arrLabels1, ref "Bar Chart", ref "X-axis", ref "Y-axis"); // Chart made from random numbers (without Bar Labels) int[] arrValues2 = new int[50]; int I = 0; VBMath.Randomize(); for (I = 0; I <= 49; I++) { arrValues2[I] = Conversion.Int((50 + 1) * Rnd()); } } public object BuildChartHTML(ref aValues, ref aLabels, ref strTitle, ref strXAxisLabel, ref strYAxisLabel) { // Some user changable graph defining constants. All units are in screen pixels const int GRAPH_WIDTH = 450; // The width of the body of the graph const int GRAPH_HEIGHT = 250; // The heigth of the body of the graph const int GRAPH_BORDER = 5; // The size of the black border const int GRAPH_SPACER = 2; // The size of the space between the bars // Debugging constant so I can eaasily switch on borders in case // the tables get messed up.

I wish this was in C#
