XtraChart控件X轴的滚动条设置

转自：http://www.cnblogs.com/WJJ-1119/archive/2012/06/20/2555814.html

 

1、XtraChart的滚动条无法在XtraReport中使用；

2、滚动条无法动态添加（一直没找到可以动态设置的方法）；

示例：

DevExpress.XtraCharts.ChartControl xrChart1 = new DevExpress.XtraCharts.ChartControl()；

DevExpress.XtraCharts.XYDiagram xyDiagram1 = new DevExpress.XtraCharts.XYDiagram();

xyDiagram1.AxisX.Range.Auto = false; //要开启滚动条必须将其设置为false xyDiagram1.AxisX.Range.MaxValueInternal = 30.5D > (cnt + 1)?(cnt + 1):30.5D;//在不拉到滚动条的时候，X轴显示多个值，既固定的X轴长度。 xyDiagram1.AxisX.Range.MinValueInternal = -0.5D; xyDiagram1.AxisX.Range.ScrollingRange.Auto = false; xyDiagram1.AxisX.Range.ScrollingRange.MaxValueSerializable = (cnt + 1).ToString();//整个X轴最多显示多多少个值 xyDiagram1.AxisX.Range.ScrollingRange.MinValueSerializable = "0"; xyDiagram1.AxisX.Range.ScrollingRange.SideMarginsEnabled = true;//是否从X轴原点开始显示 xyDiagram1.AxisX.Range.SideMarginsEnabled = false; xyDiagram1.AxisX.VisibleInPanesSerializable = "-1"; xyDiagram1.AxisY.NumericOptions.Format = DevExpress.XtraCharts.NumericFormat.Percent;//显示为百分数 xyDiagram1.AxisY.Range.Auto = false; xyDiagram1.AxisY.Range.MaxValueSerializable = "1.02"; xyDiagram1.AxisY.Range.MinValueSerializable = "0.5"; xyDiagram1.AxisY.Range.ScrollingRange.SideMarginsEnabled = true; xyDiagram1.AxisY.Range.SideMarginsEnabled = true; xyDiagram1.AxisY.VisibleInPanesSerializable = "-1"; xyDiagram1.EnableAxisXScrolling = true;//启用滚动条

xrChart1.Diagram = xyDiagram1;
