You can show this type of data in a bar chart:

DataTable dt = new DataTable();
dt.Columns.Add("year", typeof(string));
dt.Columns.Add("numUsers", typeof(int));
dt.Rows.Add(new object[] { "2005", 100 });
dt.Rows.Add(new object[] { "2006", 160 });
dt.Rows.Add(new object[] { "2007", 250 });
dt.Rows.Add(new object[] { "2008", 500 });
dt.Rows.Add(new object[] { "2009", 860 });
dt.Rows.Add(new object[] { "2010", 600 });

ultraChart1.Data.DataSource = dt;
ultraChart1.ChartType = ChartType.BarChart;
ultraChart1.Data.DataBind();
