How to substitute labels on the X axis using Chart Control of the Visual Studio 2008

[TerryGut]

I need to show actual values from Series on the X axis of the chart instead of default ones. How to do so using Chart Control of the Visual Studio 2008 Professional?

Code (just in case) is placed below. Thank you, Terry.

private void showChart(object dataSource)
{
    if (TabControlMain.TabPages.Count == 2) 
    { 
 TabControlMain.TabPages.Add(tabChart); 
    } 
    TabControlMain.SelectedTab = TabControlMain.TabPages[2]; 
    chartCyt.DataSource = dataSource; 
    chartCyt.Series[0].XValueMember = "Concentration"; 
    chartCyt.Series[0].YValueMembers = "Mean"; 
    chartCyt.Series[0].LegendText = "Mean";
    chartCyt.Series[1].XValueMember = "Concentration";
    chartCyt.Series[1].YValueMembers = "Stddev";
    chartCyt.Series[1].LegendText = "StdDev";
}
