Example 50: Gantt Chart in ASP.NET

This sample uses SeriesFactory class to add bubbles to the chart using AddBubble() method.

Steps:

1. Create a new Windows application project (C#) and name it Tutorial24_Bubble.

2. Add Super 2d/3d Graph Library to the toolbox pallete and drag it to Form1.

3. Add a button.

4. Copy and paste de following code:

namespace Tutorial24_Bubble
{

public partial class Form1 : Form
{

   public Form1()
   {
      InitializeComponent();
   }

   private void Form1_Load(object sender, EventArgs e)
   {

   // Chart basic setup
   super2d3dGraph1.AutoRefresh = false;
   super2d3dGraph1.LicenseeIdentifier = "PROF";
   super2d3dGraph1.Style = STYLE2D3D.STYLE2D_BUBBLE;
   super2d3dGraph1.Title = "Bubble Chart Sample";

   // General look & feel
   super2d3dGraph1.CastShadows = false;
   super2d3dGraph1.WallsBackStyle =
       STYLEWALLBACKGROUND.STYLEWALLBACKGROUND_GRADIENT_INVERTED;
   super2d3dGraph1.WallsBackColorPrincipal = Color.LightSkyBlue;
   super2d3dGraph1.ShowDividerX = true;
   super2d3dGraph1.BackStyle =
       STYLEBACKGROUND.STYLEBACKGROUND_GRADIENT_TUBULAR;

   // Axis scale setup
   super2d3dGraph1.XAxisScaleMinimum = 0;
   super2d3dGraph1.XAxisScaleMaximum = 100;
   super2d3dGraph1.XAxisScaleMode = SCALEMODE.SCALEMODE_FIXED;
   super2d3dGraph1.ShowXAxis = true;
   super2d3dGraph1.YAxisScaleMinimum = 0;
   super2d3dGraph1.YAxisScaleMaximum = 100;
   super2d3dGraph1.YAxisScaleMode = SCALEMODE.SCALEMODE_FIXED;
   super2d3dGraph1.YAxisNumericFormat = "0";

   // Values setup
   super2d3dGraph1.BubbleMaxRadius = 40;
   super2d3dGraph1.ShowValues = false;

   // Datatable setup
   super2d3dGraph1.DataTableText = "Bubble Sizes";
   super2d3dGraph1.ShowItemsLegend = true;
   super2d3dGraph1.ShowLegendInDataTable = false;
   super2d3dGraph1.ValuesFormat = "0";
   super2d3dGraph1.DataTableFont = new Font("Arial", 11);
   super2d3dGraph1.DataTableBackColor = Color.Lavender;

   // Legend setup
   super2d3dGraph1.ShowLegend = false;

   // Add random values
   LoadRandomData();

   // Show it
   super2d3dGraph1.RefreshChart();

   private void LoadRandomData()
   {
      SeriesFactory sf = new SeriesFactory();
      Random rnd = new Random((int)DateTime.Now.Ticks);

      for (int k = 0; k < 10; k++)
      {
         sf.AddBubble(rnd.Next(80) + 10, rnd.Next(80) + 10, rnd.Next(10));
         sf.ItemColor(Color.FromArgb(rnd.Next(255), rnd.Next(255), rnd.Next(255)));
      }
      sf.ApplyTo(super2d3dGraph1);
   }

   private void btRandomize_Click(object sender, EventArgs e)
   {
      LoadRandomData();
   }
