Hi Jingying Wu,

Currently, the chart does not support such formatting. Here is a work-around you can use:

    
            public Page() 
        
            { 
        
                InitializeComponent(); 
        
                this.RadChart1.DefaultView.ChartArea.ItemToolTipOpening += new ItemToolTipEventHandler(ChartArea_ItemToolTipOpening); 
        
            } 
        
            private void ChartArea_ItemToolTipOpening(ItemToolTip2D tooltip, ItemToolTipEventArgs e) 
        
            { 
        
                DataSeriesCollection series = this.RadChart1.DefaultView.ChartArea.DataSeries; 
        
                double sum = 0; 
        
                for (int i = 0; i < series.Count; i++) 
        
                { 
        
                    if (series[i].Count > e.ItemIndex) 
        
                        sum += series[i][e.ItemIndex].YValue; 
        
                } 
        
                tooltip.Content = string.Format("{0:p2}",e.DataPoint.YValue / sum); 
        
            }
