無法更改C＃圖表中自定義x軸標籤的文本方向

Question

我正在創建StackedColumn圖表，並且無法更改始終垂直定向的自定義x軸標籤的方向。我的代碼位於包含名爲「chart」的Chart對象的Form的Load事件中。

被註釋掉的行是我在研究時發現的嘗試修復。這些更改要麼使標籤消失，要麼沒有任何效果：

1. 切換圖表區域的x軸的IsLabelAutoFit屬性。
2. 更改LabelAutoFitStyle屬性（也用＃1測試過）。
3. 更改IntervalType和Interval屬性（也用＃1測試過）。
4. 切換LabelStyle.Enabled屬性（也用＃1測試過）。
5. 更改LabelStyle.Angle屬性（也用＃1測試過）。

這裏是我的代碼：

chart.BackColor = Color.FromArgb(211, 223, 240); 
chart.BackGradientStyle = GradientStyle.TopBottom; 
chart.BorderlineColor = Color.FromArgb(26, 59, 105); 
chart.BorderlineDashStyle = ChartDashStyle.Solid; 
chart.BorderlineWidth = 2; 
chart.BorderSkin.SkinStyle = BorderSkinStyle.Emboss; 
chart.Name = "Chart1"; 
chart.TabIndex = 1; 

var title = new Title(); 

title.Alignment = ContentAlignment.TopCenter; 
title.ForeColor = Color.FromArgb(26, 59, 105); 
title.Font = new Font("Segoe UI", 14.25F, FontStyle.Bold); 
title.ShadowColor = Color.FromArgb(32, 0, 0, 0); 
title.ShadowOffset = 3; 
title.Text = "Sales Report"; 

chart.Titles.Clear(); 
chart.Titles.Add(title); 

var chartArea = new ChartArea(); 

chartArea.AxisX.Title = "Product Sold"; 
chartArea.AxisX.LabelStyle.Font = new Font("Segoe UI", 8.25F, FontStyle.Bold); 
chartArea.AxisX.LineColor = Color.FromArgb(64, 64, 64, 64); 
chartArea.AxisX.MajorGrid.LineColor = Color.FromArgb(64, 64, 64, 64); 

chartArea.AxisX.IsLabelAutoFit = false; 
chartArea.AxisX.LabelStyle.Enabled = true; 

//chartArea.AxisX.IntervalType = DateTimeIntervalType.Number; 
//chartArea.AxisX.Interval = 1; 

//chartArea.AxisX.IsLabelAutoFit = true; 

//chartArea.AxisX.LabelAutoFitStyle = LabelAutoFitStyles.DecreaseFont; 
//chartArea.AxisX.LabelAutoFitStyle = LabelAutoFitStyles.IncreaseFont; 
//chartArea.AxisX.LabelAutoFitStyle = LabelAutoFitStyles.LabelsAngleStep30; 
//chartArea.AxisX.LabelAutoFitStyle = LabelAutoFitStyles.LabelsAngleStep45; 
//chartArea.AxisX.LabelAutoFitStyle = LabelAutoFitStyles.LabelsAngleStep90; 
//chartArea.AxisX.LabelAutoFitStyle = LabelAutoFitStyles.None; 
//chartArea.AxisX.LabelAutoFitStyle = LabelAutoFitStyles.StaggeredLabels; 
//chartArea.AxisX.LabelAutoFitStyle = LabelAutoFitStyles.WordWrap; 

//chartArea.AxisX.LabelStyle.Enabled = false; 

//chartArea.AxisX.LabelStyle.Angle = 0; 
//chartArea.AxisX.LabelStyle.Angle = 30; 

chartArea.AxisY.IsLabelAutoFit = false; 
chartArea.AxisY.Title = "Number of Closed Sales"; 
chartArea.AxisY.LabelStyle.Font = new Font("Segoe UI", 8.25F, FontStyle.Bold); 
chartArea.AxisY.LineColor = Color.FromArgb(64, 64, 64, 64); 
chartArea.AxisY.MajorGrid.LineColor = Color.FromArgb(64, 64, 64, 64); 

chartArea.Area3DStyle.Enable3D = true;

chart.ChartAreas["Default"].AxisX.CustomLabels.Add(customLabel1); 
chart.ChartAreas["Default"].AxisX.CustomLabels.Add(customLabel2);

x軸應顯示「產品A」和「產品B」作爲兩組堆疊柱的標籤。自定義標籤似乎顯示，但文本垂直方向，不能完全讀取。

Answer 1

更改此：

var customLabel1 = new CustomLabel(1, 1, "Product A", 0, LabelMarkStyle.None); 
var customLabel2 = new CustomLabel(2, 2, "Product B", 0, LabelMarkStyle.None); 

這樣：

var customLabel1 = new CustomLabel(0.5, 1.5, "Product A", 0, LabelMarkStyle.None); 
    var customLabel2 = new CustomLabel(1.5, 2.5, "Product B", 0, LabelMarkStyle.None);
