Hi All

I have been trying to bind a dataset to a bar chart without any success. Does anybody have a simple example for me.

Cheers

Simon

Hello Simon,

The following example binds the X and Y values of a series to two columns of a data table. Please let us know if you have any questions or comments.


using System;
using System.Data;
using System.Windows.Forms;
using Nevron.Chart;

namespace SimpleDataBinding
{
   public partial class Form1 : Form
   {
      DataSet m_DataSet;

      public Form1()
      {
         InitializeComponent();

         DataTable dataTable = new DataTable("MyTable");
         dataTable.Columns.Add("Position", typeof(double));
         dataTable.Columns.Add("Elevation", typeof(double));
         dataTable.Rows.Add(new object[] { 13, 22 });
         dataTable.Rows.Add(new object[] { 17, 42 });
         dataTable.Rows.Add(new object[] { 21, 14 });
         dataTable.Rows.Add(new object[] { 33, 24 });
         dataTable.Rows.Add(new object[] { 36, 31 });

         m_DataSet = new DataSet("MyDataSet");
         m_DataSet.Tables.Add(dataTable);
      }

      private void Form1_Load(object sender, EventArgs e)
      {
         NChart chart = nChartControl1.Charts[0];
         chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator = new NLinearScaleConfigurator();

         NLineSeries series = new NLineSeries();
         series.UseXValues = true;
         chart.Series.Add(series);

         nChartControl1.DataBindingManager.AddBinding(0, 0, "XValues", m_DataSet, "MyTable.Position");
         nChartControl1.DataBindingManager.AddBinding(0, 0, "Values", m_DataSet, "MyTable.Elevation");
      }
   }
}
