Winform中跨窗体设置Zedgraph的属性并刷新曲线图

场景

在利用ZedGraph时，常常有图形选项功能，设置曲线图相干属性后，

点击生存会设置另一个窗体的属性并刷新图。

结果

实现

在设置图形的选项的类中，声明委托和事件

1. //委托的界说
2. public delegate void ReloadPanelDelegete();
3. //事件声明
4. public static event ReloadPanelDelegete reloadPanelEvent;

复制代码

在当前窗体简直定按钮的点击事件中

将相干曲线图的Y轴以及X轴的相干属性存到xml设置文件中，然后调用方法

去刷新曲线图，使其重新加载。

1. private void confirmbButton_Click(object sender, EventArgs e)
2. {
3. #region 获取X轴的属性并赋值给XAxisModel
4. //对X轴的属性设置文件进行生存
5. //根据控件的 System.Windows.Forms.Control.Name 属性搜刮控件并生成由所有匹配项组成的数组。
6. //如果搜刮所有子控件，则为 true；否则为 false。
7. XAxisModel xAxisModel = new XAxisModel();
8. //获取标题
9. RadioGroup radioGroupX = this.Controls.Find("radioGroupX", true)[0] as RadioGroup;
10. xAxisModel.Title = radioGroupX.Text;
11. //获取下限
12. TextEdit minTextEditX = this.Controls.Find("minTextEditX", true)[0] as TextEdit;
13. xAxisModel.Min = Double.Parse(minTextEditX.Text);
14. //获取上限
15. TextEdit maxTextEditX = this.Controls.Find("maxTextEditX", true)[0] as TextEdit;
16. xAxisModel.Max = Double.Parse(maxTextEditX.Text);
17. //获取颜色
18. ColorEdit colorEditX = this.Controls.Find("colorEditX", true)[0] as ColorEdit;
19. xAxisModel.Color = colorEditX.Text;
20. #endregion
22. #region 将X轴的属性存到设置文件中
23. Boolean isWriteX = ChartOptionHelper.setXAxisAttribute(xAxisModel);
24. #endregion
26. #region 获取Y轴属性并赋值给List<YAxisModel>
27. List<YAxisModel> yAxisModelList = new List<YAxisModel>();
28. for (int i = 1; i <= yAxisCount; i++)
29. {
30. YAxisModel yAxisModel = new YAxisModel();
31. //获取标题
32. RadioGroup radioGroupY = this.Controls.Find("radioGroupY" + i, true)[0] as RadioGroup;
33. yAxisModel.Title = radioGroupY.Text;
34. //获取下限
35. TextEdit minTextEditY = this.Controls.Find("minTextEditY" + i, true)[0] as TextEdit;
36. yAxisModel.Min = Double.Parse(minTextEditY.Text);
37. //获取上限
38. TextEdit maxTextEditY = this.Controls.Find("maxTextEditY" + i, true)[0] as TextEdit;
39. yAxisModel.Max = Double.Parse(maxTextEditY.Text);
40. //获取颜色
41. ColorEdit colorEditY = this.Controls.Find("colorEditY" + i, true)[0] as ColorEdit;
42. yAxisModel.Color = colorEditY.Text;
43. yAxisModelList.Add(yAxisModel);
44. }
45. #endregion
47. #region 将Y轴的属性存到设置文件中
48. Boolean isWriteY = ChartOptionHelper.setYAxisAttribute(yAxisModelList);
49. #endregion
51. #region 弹出对话框并设置点击确定之后的事件
52. if (isWriteX == true && isWriteY == true)
53. {
54. if (this.Confirm("生存乐成") == DialogResult.OK)
55. {
56. //将是否第一次打开软件的标识量改为0，,下次打开直接读取设置文件
57. Global.isFirstOpen = 0;
58. if (reloadPanelEvent != null)
59. {
60. reloadPanelEvent();
61. }
62. this.Dispose();
63. }
64. }
65. else
66. {
67. DevExpress.XtraEditors.XtraMessageBox.Show("生存失败", "提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Question);
68. }
69. #endregion
71. }

复制代码

然后在曲线图显示的窗体中订阅事件

Dialog.ChartOption.reloadPanelEvent += new Dialog.ChartOption.ReloadPanelDelegete(reloadPanel);

此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，不外就是默认不显示，要使其显示，须要myPane.Y2Axis.IsVisible = true;

3.如果是三条以上Y轴的话，就要利用

1. myPane.YAxisList.Add(yAxisNew);

复制代码

加入其Y轴的list。

4.这里的需求是初次打开默认加载一条Y轴，以是在初次加载时判断

myPane.YAxisList.Count == 1，其本身的List是否为1，为1则代表是初次加载，下次再设置并加载时，其list就不为1了。以是须要是设置，而不是再往list中新增了。

5.须要注意的是，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

1. this.zedGraphControl1.Invalidate();
