piechart using devexpress, pass values from variables

Question

I'm using DevExpress for WinForms (the free one) and I'm using a 3D pie chart. I already have a chart using the Windows version and all I do is pass four variables as the values the chart needs in the series. Here's the code I use currently.

double[] yValues = { bottom, bmid, tmid, top};
string[] xNames = { "Greater than 200", "Between 200-100", "Between 100-50",                "Below 50" };

chart1.Series[0].Points.DataBindXY(xNames, yValues);

Now, I've made a DevExpress chart and tried to use:

   Devchart1.series[0].points

but points.databind does not exist. Does anyone know how I bind the data like I have using WinForms?

UPDATE Here's some more things I tried (commented out).

        double[] yValues = { bottom, bmid, tmid, top};
        string[] xNames = { "Greater than 200", "Between 200-100", "Between 100-50", "Below 50" };

        chart1.Series[0].Points.DataBindXY(xNames, yValues);

        DataTable chartTable = new DataTable("Table1");

        // Add two columns to the table.
        chartTable.Columns.Add("Names", typeof(string));
        chartTable.Columns.Add("Value", typeof(Int32));
        chartTable.Rows.Add("Below 50", top);
        chartTable.Rows.Add("Between 50-100", tmid);
        chartTable.Rows.Add("Between 100-200", bmid);
        chartTable.Rows.Add("Greater than 200", top);

        Series series1 = new Series("Series1", ViewType.Pie3D);

        chartControl2.Series.Add(series1);

        series1.DataSource = chartTable;
        series1.ArgumentScaleType = ScaleType.Qualitative;
        series1.ArgumentDataMember = "names";
        series1.ValueScaleType = ScaleType.Numerical;
        series1.ValueDataMembers.AddRange(new string[] { "Value" });
        //((Pie3DSeriesView)series1.View). = true;
        //((pie)chartControl2.Diagram).AxisY.Visible = false;
        chartControl2.Legend.Visible = false;

        // Dock the chart into its parent and add it to the current form.
        chart1.Dock = DockStyle.Fill;

::UPDATE2:: heres what happens with this code with values 101, 22, 20 and 15. enter image description here

DevExpress Series has DataSource property for binding.

Check this article. Hope it helps

UPDATE: I use your code and it seems to work fine

        DataTable chartTable = new DataTable("Table1");

        // Add two columns to the table.
        chartTable.Columns.Add("Names", typeof(string));
        chartTable.Columns.Add("Value", typeof(Int32));
        chartTable.Rows.Add("Below 50", 10);
        chartTable.Rows.Add("Between 50-100", 10);
        chartTable.Rows.Add("Between 100-200", 10);
        chartTable.Rows.Add("Greater than 200", 10);

        Series series1 = new Series("Series1", ViewType.Pie3D);

        //chartControl1.Series.Clear();
        chartControl2.Series.Add(series1);

        series1.DataSource = chartTable;
        series1.ArgumentScaleType = ScaleType.Qualitative;
        series1.ArgumentDataMember = "names";
        series1.ValueScaleType = ScaleType.Numerical;
        series1.ValueDataMembers.AddRange(new string[] { "Value" });
        //((Pie3DSeriesView)series1.View). = true;
        //((pie)chartControl2.Diagram).AxisY.Visible = false;
        chartControl2.Legend.Visible = false;
