如何可以改变X轴值在MSChart的toName我想改变图表X轴值显示月名月

Question

的

例如：1 => 1月2日，=>日等

 DataTable dt = new DataTable(); 
     SqlCommand s = new SqlCommand("ReportMonthly", SCon); 
     s.CommandType = CommandType.StoredProcedure; 
     s.Parameters.AddWithValue("@Year", Year); 
     SCon.Open(); 
     SqlDataReader dr = s.ExecuteReader(); 
     dt.Load(dr); 
     chtWRMonthly.DataSource = dt; 
     chtWRMonthly.Series["Sold"].XValueMember = "Month"; 
     chtWRMonthly.Series["sRemaining"].XValueMember = "Month"; 
     chtWRMonthly.Series["Bought"].XValueMember = "Month"; 
     chtWRMonthly.Series["bRemaining"].XValueMember = "Month"; 
     chtWRMonthly.Series["Sold"].YValueMembers = "sTAccount"; 
     chtWRMonthly.Series["sRemaining"].YValueMembers = "sRemaining"; 
     chtWRMonthly.Series["Bought"].YValueMembers = "bTAccount"; 
     chtWRMonthly.Series["bRemaining"].YValueMembers = "bRemaining"; 
     SCon.Close(); 

以及如何解决图表中的月名，然后设置其值？

例子：

Answer 1

不幸的是MSChart不允许任何真正的表情，所以我不明白你怎么可以直接整数转换到几个月。

有各种不同的解决方法，但你更喜欢将取决于你..

1）修改DataSource带回DateTimes或..

2）..to带回月份字符串。

后者将阻止你与X值的工作。

3）修改DataTable含有DateTimes;这必须在每次检索后发生。

4）由CustomLabels更换Axis.Labels完全。

这里是解决方法＃3的例子：它增加了一个新的列（“DATEX”）表中，并与来自DateTime.Now.Date加在列“C1”的整数计算日期填充。 y值在列'c2'中。

当然你应该使用合适的起始DateTime价值，而不是现在的日期！

请注意，您需要告知数据绑定关于类型的XValueMember，也许还有IntervalType！

最后，你可以格式化新栏，显示本地化（德语）本月名称..：波斯月名称

if (!DT.Columns.Contains("dateX")) DT.Columns.Add("dateX", typeof(DateTime)); 

foreach (DataRow row in DT.Rows) 
    row.SetField<DateTime>("dateX", DateTime.Now.Date.AddMonths(row.Field<int>("c1"))); 


Series s = chart1.Series[0]; 
s.XValueMember = "dateX"; 
s.XValueType = ChartValueType.DateTime; 
s.YValueMembers = "c2"; 

chart1.DataSource = DT; 
chart1.DataBind(); 

Axis ax = chart1.ChartAreas[0].AxisX; 
ax.LabelStyle.Format = "MMMM" ; 
ax.IntervalType = DateTimeIntervalType.Months; 
ax.Interval = 1;

Dictionary<string, string> MonthsDic = new Dictionary<string, string>(); 
       MonthsDic.Add("1", "فروردین"); 
       MonthsDic.Add("2", "اردیبهشت"); 
       MonthsDic.Add("3", "خرداد"); 
       MonthsDic.Add("4", "تیر"); 
       MonthsDic.Add("5", "مرداد"); 
       MonthsDic.Add("6", "شهریور"); 
       MonthsDic.Add("7", "مهر"); 
       MonthsDic.Add("8", "آبان"); 
       MonthsDic.Add("9", "آذر"); 
       MonthsDic.Add("10", "دی"); 
       MonthsDic.Add("11", "بهمن"); 
       MonthsDic.Add("12", "اسفند");
