I was able to create a bar chart with one set of bars (series) and bound it to a DataTable without any problem. Now my boss wants me to create two series - how do I bind it to a data source? Do I bind it to a DataSet or bind the DataTables to each series?

Hello Marianne,
If you want to have two BarSeries in RadChartView you can bind each separate seria to a data source by using the DataSource property. Thus, you can bind the BarSeries and add them to the Series collection. A sample example is demonstrated below:
public RadForm1()
{
InitializeComponent();
DataTable table = new DataTable();
table.Columns.Add("Value", typeof(double));
table.Columns.Add("Name", typeof(string));
table.Rows.Add(1, "John");
table.Rows.Add(3, "Adam");
table.Rows.Add(5, "Peter");
table.Rows.Add(12, "Sam");
table.Rows.Add(6, "Paul");
BarSeries barSeries = new BarSeries();
this.radChartView1.Series.Add(barSeries);
barSeries.DataSource = table;
barSeries.ValueMember = "Value";
barSeries.CategoryMember = "Name";
//barSeries2
DataTable table2 = new DataTable();
table2.Columns.Add("Value", typeof(double));
table2.Columns.Add("Name", typeof(string));
table2.Rows.Add(2, "John");
table2.Rows.Add(8, "Adam");
table2.Rows.Add(7, "Peter");
table2.Rows.Add(15, "Sam");
table2.Rows.Add(20, "Paul");
BarSeries barSeries2 = new BarSeries();
this.radChartView1.Series.Add(barSeries2);
barSeries2.DataSource = table2;
barSeries2.ValueMember = "Value";
barSeries2.CategoryMember = "Name";
}I hope this helps. If you have further questions please let me know.

Nadya
