Example

The following example demonstrates how to add custom text to data prepared by the PivotGridControl, to display it in a ChartControl.

In this event handler, you can determine the item type via the PivotCustomChartDataSourceDataEventArgs.ItemType property and change the PivotCustomChartDataSourceDataEventArgs.Value according to your custom requirements.

View Example

private void pivotGridControl1_CustomChartDataSourceData(object sender, 
PivotCustomChartDataSourceDataEventArgs e) {
    if(e.ItemType == PivotChartItemType.RowItem) {
        if(e.FieldValueInfo.Field == fieldCategoryName) {
            e.Value = CategoryEncodeTable[e.FieldValueInfo.Value.ToString()];
        } else if(e.FieldValueInfo.Field == fieldProductName) {
            string product =  
                ProductEncodeTable[e.FieldValueInfo.Value.ToString()];
            string category = 
            CategoryEncodeTable[e.FieldValueInfo.GetHigherLevelFieldValue(fieldCategoryName).ToString()];
            e.Value = product + '[' + category + ']';
        }
    }
    if(e.ItemType == PivotChartItemType.ColumnItem) {
        if(e.FieldValueInfo.ValueType == PivotGridValueType.GrandTotal) {
            e.Value = "Total Sales";
        }
    }
    if(e.ItemType == PivotChartItemType.CellItem) {
        e.Value = Math.Round(Convert.ToDecimal(e.CellInfo.Value), 0);
    }
}
