I want to color the area between a line and the vertical axis.when i use the series type "area",it always color the area between the line and the horizontal axis. there may be easy to meet my need,please help me !

Hi,

The following example displays a chart similar to the one that you sent us. If you send us the real data we can modify the example to work with it.


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

         // Setup line series
         double[] lineValuesY = new double[] { 35, 32, 30, 30, 31, 34, 39, 43, 47, 47, 46 };
         double[] lineValuesX = new double[] { 15, 17, 21, 22, 24, 27, 27, 27, 25, 23, 20 };

         NLineSeries line = new NLineSeries();
         chart.Series.Add(line);
         line.UseXValues = true;
         line.DataLabelStyle.Visible = false;
         line.MarkerStyle.Visible = true;
         line.MarkerStyle.PointShape = PointShape.Ellipse;
         line.Values.AddRange(lineValuesY);
         line.XValues.AddRange(lineValuesX);

         // Setup area series
         NAreaSeries area = new NAreaSeries();
         chart.Series.Add(area);
         area.UseXValues = true;
         area.DataLabelStyle.Visible = false;

         double[] areaValues = new double[] { 10, 20, 15, 23, 23, 23, 45, 11 };

         for (int i = 0; i < areaValues.Length; i++)
         {
            double value = areaValues[i];
            double xvalue1 = i * 5;
            double xvalue2 = (i + 1) * 5;

            area.Values.Add(value);
            area.XValues.Add(xvalue1);

            area.Values.Add(value);
            area.XValues.Add(xvalue2);
         }
      }
