The following code demonstrates how to use a Range data series to display an image inside the chart:

using System;
using System.Windows.Forms;
using Nevron.GraphicsCore;
using Nevron.Chart;
using Nevron.Chart.WinForm;

namespace TextureMappedRange
{
 public partial class Form1 : Form
 {
  public Form1()
  {
   InitializeComponent();
  }

  private void Form1_Load(object sender, EventArgs e)
  {
   // add interactivity tools
   nChartControl1.Controller.Tools.Add(new NSelectorTool());
   nChartControl1.Controller.Tools.Add(new NAxisScrollTool());
   nChartControl1.Controller.Tools.Add(new NDataZoomTool());

   // setup chart axes
   NCartesianChart chart = (NCartesianChart)nChartControl1.Charts[0];
   chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator = new NLinearScaleConfigurator();
   chart.Axis(StandardAxis.PrimaryX).ScrollBar.Visible = true;
   chart.Axis(StandardAxis.PrimaryY).ScrollBar.Visible = true;

   // add a Range series with a single data point to display the image
   NRangeSeries range = new NRangeSeries();
   range.DataLabelStyle.Visible = false;
   range.FillStyle = new NImageFillStyle("D:\\Temp\\img\\EUROPE_map.jpg");
   range.UseXValues = true;
   range.Values.Add(10);
   range.Y2Values.Add(20);
   range.XValues.Add(1);
   range.X2Values.Add(2);
   chart.Series.Add(range);

   // add a range selection for the data zoom tool
   NRangeSelection rangeSelection = new NRangeSelection();
   chart.RangeSelections.Add(rangeSelection);
  }
 }
}
