  I need to create a high low chart only

I was working over HLOC but now need an high low chart for the front page.

Please provide any thing as I am unable to search a thing.

lets see for example here is my code:

or if we need to use Finance chart?

query = objencript.Encrypt(query, true);
                System.Data.DataSet dtChart = objBlayer.fetch_dataset(query);

                // The data for the area chart
                double[] data = new double[dtChart.Tables[0].Rows.Count];

                // The labels for the area chart
                string[] labels = new string[dtChart.Tables[0].Rows.Count];

                for (int i = 0; i < dtChart.Tables[0].Rows.Count; i++)
                {
                    data[i] = Convert.ToDouble(dtChart.Tables[0].Rows[i][1].ToString());
                    labels[i] = "";///Convert.ToDateTime(dtChart.Tables[0].Rows[i][0].ToString()).ToString("yyyy-MM-dd");
                }

                // Create a XYChart object of size 300 x 300 pixels
                XYChart c = new XYChart(160, 160);

                // Set the plotarea at (45, 30) and of size 200 x 200 pixels
                c.setPlotArea(45, 30, 100, 100);

                // Add a title to the chart using 12 pts Arial Bold Italic font
                c.addTitle("SBPDR", "Arial Bold Italic", 08);

                // Add a title to the y axis
                c.yAxis().setTitle("");

                // Add a title to the x axis
                c.xAxis().setTitle("");

                // Add a green (0x00ff00) 3D area chart layer using the give data
                c.addAreaLayer(data, 0x0094ef).set3D();

                // Set the labels on the x axis.
                c.xAxis().setLabels(labels);

                // Display 1 out of 3 labels on the x-axis.
                c.xAxis().setLabelStep(3);

                // output the chart
                viewer.Image = c.makeImage();

                //include tool tip for the chart
                viewer.ImageMap = c.getHTMLImageMap("clickable", "",
                    "");

Thanks

Hi Wajid Ali,

There is a sample code included in ChartDirector called "High-Low-Open-Close Chart". It plots a HLOC chart. If you want to plot HL only, you can use empty arrays for the open and close data series. In this case, ChartDirector will only plot the High-Low part of the OHLC symbol.

Hope this can help.
