如何在mschart中添加均勻分佈在XAxis上的點？

C＃的MSChart VS2010 .NET4如何在mschart中添加均勻分佈在XAxis上的點？

chart1.Series[0].Points.AddXY(0, 1); 
    chart1.Series[0].Points.AddXY(7, 1; 
    chart1.Series[0].Points.AddXY(8,1);

我希望這3點是這樣的

.  . .

但事實證明，這樣的

. . .

爲什麼？謝謝圖表

你能告訴我們更多的代碼和圖表的截圖嗎？ – digEmAll

我很想去，但我不能上傳圖片，因爲我不允許。我可能在屬性窗口中觸摸了一些設置，但我不記得它們 – aihenry2980

ChartType是哪一個系列？點？ – digEmAll

我猜你應該使用空數據點的

代碼（見http://msdn.microsoft.com/en-us/library/dd456677.aspx）

使用IsEmpty屬性，這會導致下面的代碼。（DataManipulator.InsertEmptyPoints應該需要更少的代碼，但我沒有測試它尚未）

chart1.Series[0].Points.Add(new DataPoint(0,1)); 
chart1.Series[0].Points.Add(new DataPoint(1,0){IsEmpty=true}); 
chart1.Series[0].Points.Add(new DataPoint(2,0){IsEmpty=true}); 
chart1.Series[0].Points.Add(new DataPoint(3,0){IsEmpty=true}); 
chart1.Series[0].Points.Add(new DataPoint(4,0){IsEmpty=true}); 
chart1.Series[0].Points.Add(new DataPoint(5,0){IsEmpty=true}); 
chart1.Series[0].Points.Add(new DataPoint(6,0){IsEmpty=true}); 
chart1.Series[0].Points.Add(new DataPoint(7,1)); 
chart1.Series[0].Points.Add(new DataPoint(8,1));

似乎DataManipulator僅用於vs2012。由於性能問題，我無法添加這麼多點。 – aihenry2980

@ aihenry2980 DataManipulator出現在.Net 4中（http://msdn.microsoft.com/zh-cn/library/system.web.ui.datavisualization.charting.datamanipulator%28v=vs.100%29.aspx）我不知道看不出爲什麼你不能在VS2010 thx中使用它作爲答案，IsXValueIndexed似乎足夠用一個系列。當使用多個系列時，空DataPoints似乎更好用 – jbl

我以前從未嘗試過多個系列，我會稍後再試。 Thanx @jbl – aihenry2980

發現問題。

series1.IsXValueIndexed = true;

這是發生的原因。它應該是錯誤的。感謝大家的關注。
