I would like to draw a ScatterCharts,Use x,y,value Data. please help me.tx,

 For example:

x is Longitude in chart.

y is Dimension in chart.

 value is Population.

I can not achieve the aspirations. 

 please help me and give me  some c# code .thanks.

 use bubble chart is OK. in Matrix ,0.332 is Longitude and Dimension value.

code:

 private void ultraButton1_Click(object sender, EventArgs e)
        {
            string strLine;
            string outstring = "";
            int i = 1;int j = 1;
                string mess = @"d:\new_SWC_2.txt";
                StreamReader sr = new StreamReader(mess);
                do
                {
                    //string outstring = "";
                    strLine = sr.ReadLine();
                    if (strLine != null)
                    {
                        char[ cc = strLine.ToCharArray();
                        foreach (char c in cc)
                        {

                            if (c != 32)
                            {
                                if ((c > 47 && c < 58) || c == 46)
                                {
                                    outstring = outstring + c.ToString();
                                }
                            }
                            else
                            {
                                if (outstring.Length > 0)
                                {
                                    string uteString = i.ToString() + "," + j.ToString() + ":" + outstring + "!!!\n";
                                    //ultraTextEditor1.AppendText(uteString);
                                    if ((i / 100) > 0) {
                                        j++;
                                        i = 0;
                                    }
                                    XYZSeries aaa = new XYZSeries();
                                    if (System.Convert.ToDouble(outstring.ToString()) > 0)
                                    {
                                        aaa.Points.Add(new XYZDataPoint(i, j, System.Convert.ToDouble(outstring.ToString()), "", false));
                                        this.ultraChart1.Series.Add(aaa);
                                    }
                                    i++;
                                    outstring = "";
                                }
                            }
                        }
                    }
                } while (!sr.EndOfStream);
                sr.Close();

        }

i want to achieve,use scattercharts.
