场景

在使用zedgraph时，经常有图形选项功能，设置曲线图相关属性后，

点击保存会设置另一个窗体的属性并刷新图。

效果

 

 

实现

在设置图形的选项的类中，声明委托和事件

//委托的定义
public delegate void reloadpaneldelegete();
//事件声明
public static event reloadpaneldelegete reloadpanelevent;

 

在当前窗体的确定按钮的点击事件中

将相关曲线图的y轴以及x轴的相关属性存到xml配置文件中，然后调用方法

去刷新曲线图，使其重新加载。

private void confirmbbutton_click(object sender, eventargs e)
        {
            #region 获取x轴的属性并赋值给xaxismodel
            //对x轴的属性配置文件进行保存
            //根据控件的 system.windows.forms.control.name 属性搜索控件并生成由所有匹配项组成的数组。
            //如果搜索所有子控件，则为 true；否则为 false。
            xaxismodel xaxismodel = new xaxismodel();
            //获取标题
            radiogroup radiogroupx = this.controls.find("radiogroupx", true)[0] as radiogroup;
            xaxismodel.title = radiogroupx.text;
            //获取下限
            textedit mintexteditx = this.controls.find("mintexteditx", true)[0] as textedit;
            xaxismodel.min = double.parse(mintexteditx.text);
            //获取上限
            textedit maxtexteditx = this.controls.find("maxtexteditx", true)[0] as textedit;

            #endregion

            #region 将x轴的属性存到配置文件中

            #endregion

            #region 获取y轴属性并赋值给list<yaxismodel>

            for (int i = 1; i <= yaxiscount; i++)
            {
                yaxismodel yaxismodel = new yaxismodel();
                //获取标题
                radiogroup radiogroupy = this.controls.find("radiogroupy" + i, true)[0] as radiogroup;
                yaxismodel.title = radiogroupy.text;
                //获取下限

                yaxismodellist.add(yaxismodel);
            }
            #endregion

            boolean iswritey = chartoptionhelper.setyaxisattribute(yaxismodellist);
            #endregion

            #region 弹出对话框并设置点击确定之后的事件
            if (iswritex == true && iswritey == true)
            {
                if (this.confirm("保存成功") == dialogresult.ok)
                {

                    global.isfirstopen = 0;
                    if (reloadpanelevent != null)
                    {
                        reloadpanelevent();

                    this.dispose();
                }
            }
            else
            {
                devexpress.xtraeditors.xtramessagebox.show("保存失败", "提示", messageboxbuttons.okcancel, messageboxicon.question);
            }
            #endregion

        }

 

然后在曲线图显示的窗体中订阅事件

dialog.chartoption.reloadpanelevent += new dialog.chartoption.reloadpaneldelegete(reloadpanel);

其中左边的类是上面图形选项的类，右边的类是窗体显示的类

然后在窗体显示的类中新建图上面reloadpaneldelegete的参数同名的方法reloadpanel实现曲线图的刷新。

注：

1.mypane是zedgraph的面板，其默认是有一条y轴对象的，为mypane.yaxis

2.如果要显示第二条y轴，zedgraph是默认存在第二条y轴的，为mypane.y2axis，不过就是默认不显示，要使其显示，需要mypane.y2axis.isvisible = true;

3.如果是三条以上y轴的话，就要使用

mypane.yaxislist.add(yaxisnew);

 

加入其y轴的list。

4.这里的需求是首次打开默认加载一条y轴，所以在首次加载时判断

mypane.yaxislist.count == 1，其自己的list是否为1，为1则代表是首次加载，下次再设置并加载时，其list就不为1了。所以需要是设置，而不是再往list中新增了。

5.需要注意的是，如果显示4条y轴的话，其mypane.yaxislist.count为3，,一条是不算在内的。

6.刷新曲线图的代码

this.zedgraphcontrol1.invalidate();
