Windows Forms Controls

The code below shows how to populate a DevExpress chart with Zendesk data. The ZendeskDataAdapter 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 (ZendeskConnection connection = new ZendeskConnection( "URL=https://subdomain.zendesk.com;User=my@email.com;Password=test123;")) { ZendeskDataAdapter dataAdapter = new ZendeskDataAdapter( "SELECT Id, Subject FROM Tickets", 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[] { "Subject" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "Id"; 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 Zendesk data. The ZendeskDataAdapter 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 (ZendeskConnection connection = new ZendeskConnection( "URL=https://subdomain.zendesk.com;User=my@email.com;Password=test123;")) { ZendeskDataAdapter ZendeskDataAdapter1 = new ZendeskDataAdapter("SELECT Id, Subject FROM Tickets", connection); DataTable table = new DataTable(); ZendeskDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Subject" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Id"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
