Hello,

Thanks for your inquiry. If the max value you mentioned is Data Lable of Chart, you could use the following method to achieve it, if not, please provide us with the document you expect, you could create it directly with MS PowerPoint, and then we will look into it and provide you with the corresponding method.
Code: Select all
 int[] value = new int[chart.Series[0].Values.Count];
            for (int i = 0; i < chart.Series[0].Values.Count; i++)
            {
                value[i] = (int)chart.Series[0].Values[i].Value;
            }
            for (int i = 0; i < chart.Series[0].Values.Count; i++)
            {
                if ((int)chart.Series[0].Values[i].Value == value.Max())
                {
                    ChartDataLabel lable = chart.Series[0].DataLabels.Add();
                    lable.LabelValueVisible = true;
                }
                else
                {
                    chart.Series[0].DataLabels.Add();
                }
            }
