X Axis


Recommended Posts

Please try the following code:

DataTable dt = new DataTable();DataColumn dc1 = new DataColumn();dc1.ColumnName = "X";dc1.DataType = Type.GetType("System.Int32");DataColumn dc2 = new DataColumn();dc2.ColumnName = "Y";dc2.DataType = Type.GetType("System.Int32");dt.Columns.Add(dc1);dt.Columns.Add(dc2);......

 DataTableProvider data = new ChartFX.WebForms.DataProviders. DataTableProvider (dt);

chart1.DataSourceSettings.Fields.Add( new FieldMap ( "X" , FieldUsage .XValue)); //Setting X axis

chart1.DataSourceSettings.Fields.Add( new FieldMap ( "Y" , FieldUsage .Value)); //Setting series chart1.DataSource = data;

This my code. How do I attach a image?  I tried dragging on the default data thats loaded when the chart first comes up and it did the same thing. 


dt = New DataTable("Test")

Dim cols() As String = {"Total Time", "Time", "Bot Temp", "Pressure", "Top Temp", "MFC4", "Argon", "ArN2", "Vent"}For Each col As String In cols

dt.Columns.Add(col, Type.GetType(





cfx.DataSourceSettings.Fields.Add(New FieldMap("Total Time", FieldUsage.XValue))

For Each dc As DataColumn In dt.ColumnsIf Not dc.ColumnName.Equals("Total Time") Then cfx.DataSourceSettings.Fields.Add(New FieldMap(dc.ColumnName, FieldUsage.Value))


cfx.DataSourceSettings.DataSource =

New DataTableProvider(dt)

The way to achieve what you want is by processing the DataChangedByUser event as follows:

private void chart1_DataChangedByUser (object sender,PointLabelEventArgs e)


  if (e.Axis == chart1.AxisX)

  e.Handled = true; // Prevent change of X-Axis values


Please try it and let me know if it works for you.
