场景

Winforn中设置ZedGraph曲线图的属性、坐标轴属性、刻度属性:

Winform中实现ZedGraph的多条Y轴(附源码下载):

ZedGraph设置显示坐标值

zgc.IsShowCursorValues = true;

但是在刷新曲线图之后出现了鼠标焦点出现三个坐标值

 

 

解决方法是在其鼠标焦点悬浮事件中格式化其要显示的值,修改为举例最近的去曲线上的点。

实现

//显示焦点值事件
zgc.CursorValueEvent += zgc_CursorValueEvent;

 

然后在方法中

 

private static string zgc_CursorValueEvent(ZedGraphControl sender, GraphPane pane, Point mousePt)
        {
            
            CurveItem nearstCurve;
            int i;
            Double x = 0.0;
            Double y = 0.0;
            Global.zedGraphControl1.GraphPane.FindNearestPoint(mousePt, out nearstCurve, out i);
            if (nearstCurve!= null && nearstCurve.Points[i] != null && nearstCurve.Points[i].X != null)
            {
                 x = nearstCurve.Points[i].X;
            }
            if (nearstCurve!= null && nearstCurve.Points[i] != null && nearstCurve.Points[i].Y != null)
            {
                 y = nearstCurve.Points[i].Y;
            }
            return "X:" + x.ToString() + "  Y:" + y.ToString();
        }

 

效果
