Winform中跨窗体设置Zedgraph的属性并刷新曲线图

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;
            xAxisModel.Max = Double.Parse(maxTextEditX.Text);
            //获取颜色
            ColorEdit colorEditX = this.Controls.Find("colorEditX", true)[0] as ColorEdit;
            xAxisModel.Color = colorEditX.Text;
            #endregion

            #region 将X轴的属性存到配置文件中
            Boolean isWriteX = ChartOptionHelper.setXAxisAttribute(xAxisModel);
            #endregion

            #region 获取Y轴属性并赋值给List<YAxisModel>
            List<YAxisModel> yAxisModelList = new 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
                TextEdit minTextEditY = this.Controls.Find("minTextEditY" + i, true)[0] as TextEdit;
                yAxisModel.Min = Double.Parse(minTextEditY.Text);
                //获取上限
                TextEdit maxTextEditY = this.Controls.Find("maxTextEditY" + i, true)[0] as TextEdit;
                yAxisModel.Max = Double.Parse(maxTextEditY.Text);
                //获取颜色
                ColorEdit colorEditY = this.Controls.Find("colorEditY" + i, true)[0] as ColorEdit;
                yAxisModel.Color = colorEditY.Text;
                yAxisModelList.Add(yAxisModel);
            }
            #endregion

            #region 将Y轴的属性存到配置文件中
            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)
                {
                    //将是否第一次打开软件的标识量改为0，,下次打开直接读取配置文件
                    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。

            GraphPane myPane = new GraphPane();

        }

 

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();
