C＃图表旋转标签

我有一个简单的图表，我希望x轴上的标签旋转45度。 我究竟做错了什么？

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); 

输出是：

我正在使用System.Web.UI.DataVisualization.Charting中的图表内容。

Answer 1

文档说Series.LabelAngle设置数据点标签角度，（我认为）是图表列上方的标签。

要设置轴标签的角度，请尝试以下方法：

 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

以下是我通常旋转X轴标签的方法。

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

结果

上面看的关键属性/行是“LabelAutoFitStyle”。

Answer 3

我需要这些线才能使它工作：

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