Windows Forms Controls

The code below shows how to populate a DevExpress chart with Zoho CRM data. The ZohoCRMDataAdapter binds to the Series property of the chart control. The Diagram property of the control defines the x- and y-axes as the column names.

using (ZohoCRMConnection connection = new ZohoCRMConnection( "AuthToken=2ad3b3e719f6bed7368e5e7e26e4f988;")) { ZohoCRMDataAdapter dataAdapter = new ZohoCRMDataAdapter( "SELECT Account_Name, Annual_Revenue FROM Accounts", connection); DataTable table = new DataTable(); dataAdapter.Fill(table); DevExpress.XtraCharts.Series series = new DevExpress.XtraCharts.Series(); chartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Annual_Revenue" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "Account_Name"; series.ValueScaleType = DevExpress.XtraCharts.ScaleType.Numerical; chartControl1.Legend.Visibility = DevExpress.Utils.DefaultBoolean.False; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }

Web Controls

The code below shows how to populate a DevExpress Web control with Zoho CRM data. The ZohoCRMDataAdapter binds to the Series property of the chart; the Diagram property defines the x- and y-axes as the column names.

using DevExpress.XtraCharts; using (ZohoCRMConnection connection = new ZohoCRMConnection( "AuthToken=2ad3b3e719f6bed7368e5e7e26e4f988;")) { ZohoCRMDataAdapter ZohoCRMDataAdapter1 = new ZohoCRMDataAdapter("SELECT Account_Name, Annual_Revenue FROM Accounts", connection); DataTable table = new DataTable(); ZohoCRMDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Annual_Revenue" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Account_Name"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
