How can I draw a Radar Chart using Microsoft Chart Control for .NET Framework 3.5. I can draw "column" chart using the following code from MSDN. I could not find any example for Radar Chart.
Series ChampionshipsSeries = chtNBAChampionships2.Series["Championships"]; //Add data points ChampionshipsSeries.Points.AddXY("Celtics", 17); ChampionshipsSeries.Points.AddXY("Lakers", 15); ChampionshipsSeries.Points.AddXY("Bulls", 6); ChampionshipsSeries.Points.AddXY("Spurs", 4); ChampionshipsSeries.Points.AddXY("76ers", 3); ChampionshipsSeries.Points.AddXY("Pistons", 3); ChampionshipsSeries.Points.AddXY("Warriors", 3);
Looking for your kind help.
Finally I managed myself after doing experimenting with the examples from the following source,
Samples for Chart Control - .NET Framework 4
Though the examples are for .NET Framework 4, I tried it in .NET Framework 3.5 for Radar Chart and it worked.
If you are interested you may have a look at this page, http://nazmulweb.com/site5/demo/chart/
Later on , I have found the examples for .NET Freamework 3.5 from http://code.msdn.microsoft.com/mschart/Release/ProjectReleases.aspx?ReleaseId=1591
As a ready reference, you can follow this one,
/* -------------------------- Criteria Volvo Toyota -------- ----- ------ Speed 37 23 Fuel 32 19 Comfort 38 31 Safety 39 33 -------------------------- */ DataTable dt = new DataTable(); dt.Columns.Add("Criteria"); dt.Columns.Add("Volvo"); dt.Columns.Add("Toyota"); DataRow dr1 = dt.NewRow(); dr1.ItemArray = new object[] { "Speed", 37, 23 }; dt.Rows.Add(dr1); DataRow dr2 = dt.NewRow(); dr2.ItemArray = new object[] { "Fuel", 32, 19 }; dt.Rows.Add(dr2); DataRow dr3 = dt.NewRow(); dr3.ItemArray = new object[] { "Comfort", 38, 31 }; dt.Rows.Add(dr3); DataRow dr4 = dt.NewRow(); dr4.ItemArray = new object[] { "Price", 39, 33 }; dt.Rows.Add(dr4); Chart aRadarChart = new Chart(); aRadarChart.Width = Unit.Pixel(500); aRadarChart.DataSource = dt; // Add title aRadarChart.Titles.Add("TOYOTA VS VOLVO"); // Add a legend Legend lgnd = new Legend(); lgnd.Enabled = true; aRadarChart.Legends.Add(lgnd); //Important: add ChartArea, otherwise no graph will be shown ChartArea ca = new ChartArea("myChartArea"); aRadarChart.ChartAreas.Add(ca); string car = String.Empty; for (int i = 1; i < dt.Columns.Count; i++) { car = dt.Columns[i].ColumnName; aRadarChart.Series.Add(car);//Name of the series :Volvo and Toyota aRadarChart.Series[car].YValueMembers = car;//Either Volvo or Toyota aRadarChart.Series[car].XValueMember = dt.Columns[0].ColumnName;//Criteria //Define here: what kind of Chart you want aRadarChart.Series[car].ChartType = SeriesChartType.Radar; } //binding data aRadarChart.DataBind(); //Add Chart to a PlaceHolder Control plhForChart.Controls.Add(aRadarChart); //Page.Controls.Add(aRadarChart); //for saving image aRadarChart.SaveImage(Server.MapPath("App_Data/Sample.jpg"));
