For this, it is necessary to handle the PivotGridControl.CustomChartDataSourceData event. 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.

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);
    }
}
