救急！！！Dev的chartControl画曲线图，怎么控制X轴的标签间隔显示？

[百思软件工作室]

Dev的chartControl画曲线图，怎么控制X轴的标签间隔显示？

我X轴是时间，Y轴是金额；
现在记录有100多个，标签在X轴都显示出来了，数字密密麻麻；
麻烦问下，怎么控制X轴的标签间隔显示？

希望能提供一下测试通过的代码;谢谢了。

要设置下 series1.ArgumentScaleType = ScaleType.DateTime;//x轴类型 这个 Series series1 = new Series(this.Text, ViewType.Spline); series1.ArgumentScaleType = ScaleType.DateTime;//x轴类型 series1.ValueScaleType = ScaleType.Numerical;//y轴类型 //X轴的数据字段 series1.ArgumentDataMember = "StatisticsTime"; //Y轴的数据字段 series1.ValueDataMembers[0] = "StatisticsSum"; //定义线条上点的标识形状是否需要 ((LineSeriesView)series1.View).LineMarkerOptions.Visible = false; //定义线条上点的标识形状 ((LineSeriesView)series1.View).LineMarkerOptions.Kind = MarkerKind.Circle; //不显示X、Y轴上面的交点的值 ((PointSeriesLabel)series1.Label).Visible = false; //线条的类型，虚线，实线 ((LineSeriesView)series1.View).LineStyle.DashStyle = DashStyle.Solid; 完整代码分享给你，给满分哟： public void BindChart(DataTable datatable, ChartControl myChartControl) { myChartControl.Name = "chartResult"; myChartControl.Dock = DockStyle.Fill; myChartControl.Size = new System.Drawing.Size(400, 250); // 显示标签. myChartControl.Legend.Visible = true; myChartControl.Series.Clear(); #region 仅供参考（不需要） //控制X、Y轴显示 //XYDiagram diagram = (XYDiagram)chartControl.Diagram; //diagram.AxisX.Label.Staggered = true; //diagram.AxisY.Label.BeginText = "Axis value = "; //diagram.AxisY.Label.Angle = -30; //diagram.AxisY.Label.Antialiasing = true; //XYDiagram diagram = (XYDiagram)chartControl.Diagram; //diagram.AxisX.DateTimeMeasureUnit = DateTimeMeasurementUnit.Second; //diagram.AxisX.DateTimeOptions.Format = DateTimeFormat.Custom; diagram.AxisX.DateTimeOptions.FormatString = "HH:mm:ss"; //((XYDiagram)myChartControl.Diagram).AxisX.Interlaced = true; //((XYDiagram)myChartControl.Diagram).AxisX.GridSpacing = 10; //((XYDiagram)myChartControl.Diagram).AxisX.Label.Angle = -30; //((XYDiagram)myChartControl.Diagram).AxisX.Label.Antialiasing = true; //((XYDiagram)myChartControl.Diagram).AxisX.DateTimeOptions.Format = DateTimeFormat.MonthAndDay; ////XYDiagram xyDiagram1 = new 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) ?

这个代码能实现间隔设置吗？好像不能啊！！！

[xuehan1108]

解决了吗？我现在也遇到这个问题，求分享。

XYDiagram xyDiagram1 = chartControl1.Diagram as 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 = true; // xyDiagram1.AxisY.Range.MaxValueSerializable = "1.02";//固定Y轴的高度 //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

这个非常灵活，能控制滚动状态

你好，我也遇到这个问题 ，想要固定X坐标轴，你这个里面的cnt是什么呀，求指导。
