在asp.net折线图中将轴标签值从数字替换为char

Question

我正在研究asp.net图表。我想将标签上显示的值从数字替换为char。 代码：

string[] XPointMember = new string[ChartData.Rows.Count];
decimal[] YPointMember = new decimal[ChartData.Rows.Count];
for (int count = 0; count < ChartData.Rows.Count; count++)
{
  //storing Values for X axis  
  XPointMember[count] = ChartData.Rows[count]["Time"].ToString();
  //storing values for Y Axis  
  YPointMember[count] = Convert.ToDecimal(ChartData.Rows[count][j]);
}
_chart.Series[j - 1].Points.DataBindXY(XPointMember, YPointMember);

示例如下

我想如下

有没有办法做到这一点。
