本文介绍了DevExpress的ChartControl控件的使用方法，包括设置X、Y轴显示、图表滚动、日期时间格式、图例和标题的配置，以及系列数据的绑定。通过示例代码展示了如何调整轴的属性、标签角度、滚动条、数据格式和线条样式。

xyDiagram1.AxisX.Range.ScrollingRange.MaxValueSerializable = (cnt + 1).ToString();//整个X轴最多显示多多少个值

获取Diagram必须在ChartControl中已经加入了Series之后
((XYDiagram)chartControl.Diagram).Rotated = false;

myChartControl.Legend.AlignmentHorizontal = LegendAlignmentHorizontal.Right;
myChartControl.Legend.AlignmentVertical = LegendAlignmentVertical.Top;

ChartTitle chartTitle = new ChartTitle();

Series series1 = new Series(this.Text, ViewType.Spline);

//X轴的数据字段
