Spread Studio 表格控件数据可视化：波形图-设置样式

Spread 表格控件一直致力于增强用户体验。在继 V6 版本中新增了 波形图 之后，最新发布的 Spread Studio for .NET 中针对数据可视化做了很多的增强。增强条件格式是其中的亮点之一。我们将用两片文章来阐述 Spread 数据可视化相关方面的内容，本系列文章将详细介绍波形图的使用方法。

在本片文章中将阐述如何定制波形图的样式。

使用代码：

1.设置波形图的数据单元格

2.设置波形图的显示位置

3.设置波形图的标记颜色

4.添加波形图到目标位置

实例代码如下：

C#

  1:  FarPoint.Win.Spread.SheetView sv = new FarPoint.Win.Spread.SheetView();

  2:  FarPoint.Win.Spread.Chart.SheetCellRange data = new FarPoint.Win.Spread.Chart.SheetCellRange(sv, 0,0,1, 5);

  3:  FarPoint.Win.Spread.Chart.SheetCellRange data2 = new FarPoint.Win.Spread.Chart.SheetCellRange(sv, 5,0,1,1);

  4:  FarPoint.Win.Spread.ExcelSparklineSetting ex = new FarPoint.Win.Spread.ExcelSparklineSetting();

  5:  ex.AxisColor = Color.SaddleBrown;

  6:  ex.ShowFirst = true;

  7:  ex.ShowHigh = true;

  8:  ex.ShowLow = true;

  9:  ex.ShowLast = true;

 10:  ex.FirstMarkerColor = Color.Blue;

 11:  ex.HighMarkerColor = Color.DarkGreen;

 12:  ex.MarkersColor = Color.Aquamarine;

 13:  ex.LowMarkerColor = Color.Red;

 14:  ex.LastMarkerColor = Color.Orange;

 15:  ex.ShowMarkers = true;

 16:  fpSpread1.Sheets[0] = sv;

 17:  sv.Cells[0, 0].Value = 2;

 18:  sv.Cells[0, 1].Value = 5;

 19:  sv.Cells[0, 2].Value = 4;

 20:  sv.Cells[0, 3].Value = 1;

 21:  sv.Cells[0, 4].Value = 3;

 22:  fpSpread1.Sheets[0].AddSparkline(data, data2, FarPoint.Win.Spread.SparklineType.Line, ex);

VB.NET

  1:  Dim sv As New FarPoint.Win.Spread.SheetView()

  2:  Dim data As New FarPoint.Win.Spread.Chart.SheetCellRange(sv, 0, 0, 1, 5)

  3:  Dim data2 As New FarPoint.Win.Spread.Chart.SheetCellRange(sv, 5, 0, 1, 1)

  4:  Dim ex As New FarPoint.Win.Spread.ExcelSparklineSetting()

  5:  ex.AxisColor = Color.SaddleBrown

  6:  ex.ShowFirst = True

  7:  ex.ShowHigh = True

  8:  ex.ShowLow = True

  9:  ex.ShowLast = True

 10:  ex.FirstMarkerColor = Color.Blue

 11:  ex.HighMarkerColor = Color.DarkGreen

 12:  ex.MarkersColor = Color.Aquamarine

 13:  ex.LowMarkerColor = Color.Red

  14:  ex.LastMarkerColor = Color.Orange

 15:  ex.ShowMarkers = True

 16:  FpSpread1.Sheets(0) = sv

 17:  sv.Cells(0, 0).Value = 2

 18:  sv.Cells(0, 1).Value = 5

 19:  sv.Cells(0, 2).Value = 4

 20:  sv.Cells(0, 3).Value = 1

 21:  sv.Cells(0, 4).Value = 3

 22:  FpSpread1.Sheets(0).AddSparkline(data, data2, FarPoint.Win.Spread.SparklineType.Line, ex)

效果图：

使用 Spread 设计器设置：

1.输入用于创建波形图的数据。

2.选择单元格作为波形图的显示位置。

3.选择 ”插入“菜单项。

4.选择波形图类型。

5.在弹出的波形图对话框中选择数据。

6.点击确定。

7. 选择波形图在波形图菜单中设置波形图颜色。

8.保存你的更改，在文件菜单中选择”应用并退出“，退出设计器。
