C＃圖表旋轉標籤

Question

我有一個簡單的圖表，我希望X軸上的標籤旋轉45度。我究竟做錯了什麼？

Chart c = new Chart(); 
c.ChartAreas.Add(new ChartArea()); 
c.Width = 200; 
c.Height = 200; 
Series mySeries = new Series(); 
mySeries.Points.DataBindXY(new string[] { "one", "two", "three" }, new int[] { 1, 2, 3 }); 
mySeries.LabelAngle = 45; // why doesn't this work? 
c.Series.Add(mySeries); 

輸出是：

我使用的是從System.Web.UI.DataVisualization.Charting製圖的東西。

Answer 1

該文檔說，Series.LabelAngle設置數據點標籤的角度，這（我認爲）是圖表列的上方的標籤。

要設置軸標籤的角度試試這個：

var c = Chart1; 
c.ChartAreas.Add(new ChartArea()); 
c.Width = 200; 
c.Height = 200; 
Series mySeries = new Series(); 
mySeries.Points.DataBindXY(new string[] { "one", "two", "three" }, new int[] { 1, 2, 3 }); 
//mySeries.LabelAngle = -45; // why doesn't this work? 
c.Series.Add(mySeries); 
c.ChartAreas[0].AxisX.LabelStyle.Angle = 45; // this works 

Answer 2

下面是我通常我的旋轉X軸標籤。

ChartArea area = new ChartArea(); 
area.AxisX.IsLabelAutoFit = true; 
area.AxisX.LabelAutoFitStyle = LabelAutoFitStyles.LabelsAngleStep30; 
area.AxisX.LabelStyle.Enabled = true; 

結果

的關鍵性質/線在高於看是 「LabelAutoFitStyle」。

Answer 3

我需要這些行得到它的工作：

chartarea.AxisX.LabelStyle.Angle = -90; 
chartarea.AxisX.IntervalAutoMode = IntervalAutoMode.VariableCount; 
chartarea.AxisX.IsLabelAutoFit = false;
