  • Include the FusionCharts.DataEngine and FusionCharts.Visualization .dll files.
  • Create DataTable.
  • Retrieve data using database query.
  • Set server name.
  • Set DataBase name.
  • Connect with DataBase using a connection string.
  • Create StaticSource using the DataTable.
  • Create an instance of DataModel class.
  • Add DataSource to the DataModel.
  • Instantiate Funnel Chart.
  • Set chart width and height.
  • Set DataModel instance as the data source of the chart.
  • Set Chart Title.
  • Finally, use a container using <div> to render the chart.

The code is shown below:

using FusionCharts.Visualization;
using FusionCharts.DataEngine;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
namespace FusionChartsVisualisationWebFormsSamples.Samples {
    public partial class FunnelChart : System.Web.UI.Page {
        protected void Page_Load(object sender, EventArgs e) {
            // Create data table
            DataTable primaryData = new DataTable();

            // Retrieve data using database query
            string query = "select [Website Sections], [Website Visits] from dbo.WebsiteVisits";
            string connetionstring = null;

            // Servevr name
            string serverName = "FusionChartsServer";

            // DataBase name
            string databaseName = "FusionChartsSamplesDB";
            ChartData.Clear();

            // Connection string
            connetionstring = "Data Source=" + serverName + ";Initial Catalog=" + databaseName + ";Trusted_Connection=true;";

            using (SqlConnection con = new SqlConnection(connetionstring))
            {
                con.Open();
                using (SqlCommand command = new SqlCommand(query, con))
                using (SqlDataAdapter da = new SqlDataAdapter(command))
                {
                    da.Fill(ChartData);
                }
            }
            StaticSource source = new StaticSource(ChartData);
            DataModel model = new DataModel();
            model.DataSources.Add(source);
            Charts.FunnelChart funnel = new Charts.FunnelChart("first_Funnel_chart");
            funnel.Data.Source = model;
            funnel.Caption.Text = "Visit to purchase analysis";
            funnel.Caption.Text = "Harry's Supermart";
            funnel.SubCaption.Text = "Visit to purchase- Conversion Anallysis for last year";
            funnel.Width = "600";
            funnel.Height = "400";
            Literal1.Text = funnel.Render();
        }
    }
}
