（一）導(dǎo)出圖表
1.1 可用格式
可用導(dǎo)出格式，可以將所有格式復(fù)制到文件或剪貼板或Stream。
1.1.1 圖像格式
- BMP: BitmapFormat Class
- JPEG: JPEGFormat Class
- WMF & EMF: MetafileFormat Class
- GIF: GIFFormat Class
- PNG: PNGFormat Class
- TIFF: TIFFFormat Class
1.1.2 數(shù)據(jù)格式
- Text: TextFormat Class
- XML: XMLFormat Class
- HTML: HTMLFormat Class
- Excel: ExcelFormat Class
1.1.3 其他格式
TEN格式是一種靈活的格式，可存儲圖表屬性信息和（可選）圖表數(shù)據(jù)，文件很小（取決于數(shù)據(jù)），非常適合網(wǎng)絡(luò)用于更新基于實時客戶端的圖表。
- TEN (TeeChart): TemplateExport Classs
1.2 示例導(dǎo)出
導(dǎo)出到文件是合理的，在大多數(shù)情況下，只需要定義目標(biāo)文件名。
[C#.Net]
private void button1_Click(object sender, System.EventArgs e)
saveFileDialog1.Filter = "Images (*.bmp)|*.bmp|Images(*.jpg)|*.jpg|Images(*.wmf)|*.wmf|Images(*.emf)|*.emf|Images (*.gif)|*.gif|Images (*.png)|*.png|Images (*.tiff)|*.tiff";
saveFileDialog1.ShowDialog();
if(saveFileDialog1.FileName != "")
switch(saveFileDialog1.FilterIndex)
case 1:
tChart1.Export.Image.Bitmap.Save(saveFileDialog1.FileName);
break;
case 2:
tChart1.Export.Image.JPEG.Save(saveFileDialog1.FileName);
break;
case 3:
tChart1.Export.Image.Metafile.Enhanced = false;
tChart1.Export.Image.Metafile.Save(saveFileDialog1.FileName);
break;
case 4:
tChart1.Export.Image.Metafile.Enhanced = true;
tChart1.Export.Image.Metafile.Save(saveFileDialog1.FileName);
break;
case 5:
tChart1.Export.Image.GIF.Save(saveFileDialog1.FileName);
break;
case 6:
tChart1.Export.Image.PNG.Save(saveFileDialog1.FileName);
break;
case 7:
tChart1.Export.Image.TIFF.Save(saveFileDialog1.FileName);
break;
[VB.Net]
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
SaveFileDialog1.Filter = "Images (*.bmp)|*.bmp|Images(*.jpg)|*.jpg|Images(*.wmf)|*.wmf|Images(*.emf)|*.emf|Images (*.gif)|*.gif|Images (*.png)|*.png|Images (*.tiff)|*.tiff"
SaveFileDialog1.ShowDialog()
If SaveFileDialog1.FileName <> "" Then
Select Case SaveFileDialog1.FilterIndex
Case 1
TChart1.Export.Image.Bitmap.Save(SaveFileDialog1.FileName)
Case 2
TChart1.Export.Image.JPEG.Save(SaveFileDialog1.FileName)
Case 3
TChart1.Export.Image.Metafile.Enhanced = False
TChart1.Export.Image.Metafile.Save(SaveFileDialog1.FileName)
Case 4
TChart1.Export.Image.Metafile.Enhanced = True
TChart1.Export.Image.Metafile.Save(SaveFileDialog1.FileName)
Case 5
TChart1.Export.Image.GIF.Save(SaveFileDialog1.FileName)
Case 6
TChart1.Export.Image.PNG.Save(SaveFileDialog1.FileName)
Case 7
TChart1.Export.Image.TIFF.Save(SaveFileDialog1.FileName)
End Select
End If
End Sub
（二） 導(dǎo)出圖像
2.1 BMP
BMP文件導(dǎo)出具有顏色和大小的附加參數(shù)。例：
[C#.Net]
case 1:
Steema.TeeChart.Export.BitmapFormat bitMap = tChart1.Export.Image.Bitmap;
bitMap.Height = 500;
bitMap.Width = 700;
bitMap.Monochrome = true;
bitMap.Save(saveFileDialog1.FileName);
break;
[VB.Net]
Case 1
Dim BitMap As Steema.TeeChart.Export.BitmapFormat = TChart1.Export.Image.Bitmap
BitMap.Height = 500
BitMap.Width = 700
BitMap.Monochrome = True
BitMap.Save(SaveFileDialog1.FileName)
2.2 JPEG
JPEG文件導(dǎo)出現(xiàn)在具有SaveToFile和SaveToStream的速度和質(zhì)量參數(shù)，例
[C#.Net]
case 2:
Steema.TeeChart.Export.JPEGFormat jPEG = tChart1.Export.Image.JPEG;
jPEG.GrayScale = true;
jPEG.Height = 500;
jPEG.Width = 700;
jPEG.Quality = 100;
jPEG.Save(saveFileDialog1.FileName);
break;
[VB.Net]
Case 2
Dim JPEGf As Steema.TeeChart.Export.JPEGFormat = TChart1.Export.Image.JPEG
JPEGf.Height = 500
JPEGf.Width = 700
JPEGf.GrayScale = True
JPEGf.Quality = 100
JPEGf.Save(SaveFileDialog1.FileName)
Quality value質(zhì)量值（從1到100）將使文件更大，網(wǎng)絡(luò)傳輸就慢，但質(zhì)量更好！您需要根據(jù)自己的應(yīng)用決定最佳平衡。通過將“Enhanced”設(shè)置為True簡單地創(chuàng)建
2.3 WMF & EMF
通過將“Enhanced”設(shè)置為True，可以簡單地創(chuàng)建增強型圖元文件，例：
[C#.Net]
case 3:
Steema.TeeChart.Export.MetafileFormat metaFile = tChart1.Export.Image.Metafile;
metaFile.Height = 500;
metaFile.Width = 700;
metaFile.Enhanced = false;
metaFile.Save(saveFileDialog1.FileName);
break;
[VB.Net]
Case 3
Dim MetaFile As Steema.TeeChart.Export.MetafileFormat = TChart1.Export.Image.Metafile
MetaFile.Height = 500
MetaFile.Width = 700
MetaFile.Enhanced = False
MetaFile.Save(SaveFileDialog1.FileName)
2.4 GIF
由于Microsoft的.Net Framework類庫，特別是System.Drawing.Imaging命名空間中包含的類，TeeChart for .Net能夠支持以GIF格式導(dǎo)出位圖。 到目前為止，尚不清楚在其應(yīng)用程序中實現(xiàn)這些類的開發(fā)人員是否需要從Unisys獲得GIF專利許可。
[C#.Net]
case 5:
Steema.TeeChart.Export.GIFFormat gIF = tChart1.Export.Image.GIF;
gIF.Height = 500;
gIF.Width = 700;
gIF.ColorReduction = Steema.TeeChart.Export.GIFFormat.GIFColorReduction.GrayScale;
gIF.Save(saveFileDialog1.FileName);
break;
[VB.Net]
Case 5
Dim GIF As Steema.TeeChart.Export.GIFFormat = TChart1.Export.Image.GIF
GIF.Height = 500
GIF.Width = 700
GIF.ColorReduction = Steema.TeeChart.Export.GIFFormat.GIFColorReduction.GrayScale
GIF.Save(SaveFileDialog1.FileName)
2.5 PNG
PNG格式保留了GIF格式的許多優(yōu)點，但也提供了超出GIF格式的功能，PNG改進了GIF逐步顯示圖像的能力。 也就是說，當(dāng)圖像通過網(wǎng)絡(luò)連接到達時，顯示更好和更好的圖像近似值，例
[C#.Net]
case 6:
Steema.TeeChart.Export.PNGFormat pNG = tChart1.Export.Image.PNG;
pNG.Compression = 100;
pNG.GrayScale = true;
pNG.Height = 500;
pNG.Width = 700;
pNG.Save(saveFileDialog1.FileName);
break;
[VB.Net]
Case 6
Dim PNGf As Steema.TeeChart.Export.PNGFormat = TChart1.Export.Image.PNG
PNGf.Compression = 100
PNGf.GrayScale = True
PNGf.Height = 500
PNGf.Width = 700
PNGf.Save(SaveFileDialog1.FileName)
2.6 TIFF
TIFF是一種靈活且可擴展的格式，受到各種平臺和圖像處理應(yīng)用程序的支持，例
[C#.Net]
case 7:
Steema.TeeChart.Export.TIFFFormat tIFF = tChart1.Export.Image.TIFF;
tIFF.Compression = Steema.TeeChart.Export.TIFFFormat.TIFFCompression.LZW;
tIFF.Height = 500;
tIFF.Width = 700;
tIFF.Save(saveFileDialog1.FileName);
break;
[VB.Net]
Case 7
Dim TIFF As Steema.TeeChart.Export.TIFFFormat = TChart1.Export.Image.TIFF
TIFF.Compression = Steema.TeeChart.Export.TIFFFormat.TIFFCompression.LZW
TIFF.Height = 500
TIFF.Width = 700
TIFF.Save(SaveFileDialog1.FileName)
2.7 Adobe Flex/Flash/SWF
TeeChart現(xiàn)在可以導(dǎo)出為Adobe Flex腳本文件（* .mxml），然后可以通過Flex的免費編譯器（mxmlc.exe）進行編譯，以創(chuàng)建* .swf（Flash）文件。
（三）導(dǎo)出數(shù)據(jù)
系列數(shù)據(jù)有四種導(dǎo)出格式：
- Text: TextFormat Class
- XML: XMLFormat Class
- HTML: HTMLFormat Class
- Excel: ExcelFormat Class
上述組件可以與圖表系列相關(guān)聯(lián)，從中可以將數(shù)據(jù)導(dǎo)出為文件，Stream或剪貼板。以下示例將圖表系列中的數(shù)據(jù)導(dǎo)出到HTML表：
[C#.Net]
private void Form1_Load(object sender, System.EventArgs e)
Random rnd = new Random();
char c = new char();
for(int i = 0; i < 10; ++i)
c = Convert.ToChar(65 + i);
bar1.Add(Convert.ToDouble(i),rnd.Next(100),c.ToString(),Color.Red);
Steema.TeeChart.Export.DataExport dataExport = new Steema.TeeChart.Export.DataExport(tChart1.Chart);
dataExport.HTML.IncludeHeader = true;
dataExport.HTML.IncludeIndex = true;
dataExport.HTML.IncludeLabels = true;
dataExport.HTML.Series = bar1;
dataExport.HTML.Save(@"C:.htm");
[VB.Net]
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim C As New Char()
Dim i As New Integer()
For i = 0 To 10
C = Convert.ToChar(65 + i)
Bar1.Add(Convert.ToDouble(i), Rnd() * 100, C.ToString(), Color.Red)
Next
Dim DataExport As New Steema.TeeChart.Export.DataExport(TChart1.Chart)
DataExport.HTML.IncludeHeader = True
DataExport.HTML.IncludeIndex = True
DataExport.HTML.IncludeLabels = True
DataExport.HTML.Series = Bar1
DataExport.HTML.Save("C:.htm")
End Sub
帶有隨機數(shù)據(jù)集的上述輸出如下：
<table border="1">
<tr><td>Index</td><td>Text</td><td>bar1</td></tr>
<tr><td>0</td><td>A</td><td>69</td></tr>
<tr><td>1</td><td>B</td><td>93</td></tr>
<tr><td>2</td><td>C</td><td>18</td></tr>
<tr><td>3</td><td>D</td><td>88</td></tr>
<tr><td>4</td><td>E</td><td>42</td></tr>
<tr><td>5</td><td>F</td><td>33</td></tr>
<tr><td>6</td><td>G</td><td>58</td></tr>
<tr><td>7</td><td>H</td><td>43</td></tr>
<tr><td>8</td><td>I</td><td>63</td></tr>
<tr><td>9</td><td>J</td><td>49</td></tr>
</table>
（四）TeeChart的'Ten'模板和數(shù)據(jù)導(dǎo)出/導(dǎo)入格式
Ten files
Ten files是TeeChart自己的模板格式，用于保存圖表及其數(shù)據(jù)。 修改的圖表屬性隨模板一起保存，并在模板導(dǎo)入新圖表時重現(xiàn)，優(yōu)點：
- 大小非常小，在大多數(shù)情況下，它提供了優(yōu)于純圖形格式（qicker）的優(yōu)勢。
- 模板的目標(biāo)圖表是“live實時”，可以進行縮放和滾動，并修改其屬性。
- 根據(jù)用戶的喜好，數(shù)據(jù)可以選擇包含在十個模板中。
例：
[C#.Net]
private void button1_Click(object sender, System.EventArgs e)
saveFileDialog1.Filter = "TenFile (.ten)|*.ten";
saveFileDialog1.ShowDialog();
if(saveFileDialog1.FileName != "")
tChart1.Export.Template.IncludeData = true;
tChart1.Export.Template.Save(saveFileDialog1.FileName);
[VB.Net]
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
SaveFileDialog1.Filter = "TenFile (.ten)|*.ten"
SaveFileDialog1.ShowDialog()
If SaveFileDialog1.FileName <> "" Then
TChart1.Export.Template.IncludeData = True
TChart1.Export.Template.Save(SaveFileDialog1.FileName)
End If
End Sub
（五）導(dǎo)入
5.1 將XML導(dǎo)入TeeChart
5.1.1 從TextBox導(dǎo)入XML
[C#.Net]
protected override void button1_Click(object sender, System.EventArgs e)
tChart1.Series.RemoveAllSeries();
Steema.TeeChart.Styles.Points points1 = new Steema.TeeChart.Styles.Points(tChart1.Chart);
points1.Title = "Points Series";
xmlSource1.Series = points1;
xmlSource1.SeriesNode = "Points Series";
xmlSource1.Load(textBox2.Text);
tChart1.Refresh();
5.1.2 從URL導(dǎo)入XML
[C#.Net]
protected override void button2_Click(object sender, System.EventArgs e)
tChart1.Series.RemoveAllSeries();
xmlSource1.Chart = tChart1.Chart;
xmlSource1.Load("//www.steema.com/SampleNETData.xml");
tChart1.Refresh();
5.2 導(dǎo)入Ten格式文件
從本地文件源或http數(shù)據(jù)源導(dǎo)入已保存的Ten文件。
5.3 導(dǎo)入示例
5.3.1 從文件導(dǎo)入
[C#.Net]
tChart1.Import.Template.LoadFileDialog();
[VB.Net]
TChart1.Import.Template.LoadFileDialog()
5.3.2 URl
[C#.Net]
tChart1.Import.Template.FromURL("//www.berneda.com/demo.ten");
[VB.Net]
TChart1.Import.Template.FromURL("//www.berneda.com/demo.ten")
5.3.3 Stream
[C#.Net]
System.IO.MemoryStream tenStream = new System.IO.MemoryStream();
tChart1.Export.Template.Save(tenStream);
tChart2.Import.Template.Load(tenStream);
[VB.Net]
Dim TenStream As New System.IO.MemoryStream()
TChart1.Export.Template.Save(TenStream)
TChart2.Import.Template.Load(TenStream)
5.4 導(dǎo)入圖表所做更改的效果
As.ten文件時所做更改的效果僅保存對標(biāo)準(zhǔn)圖表定義的更改，如果目標(biāo)圖表包含未導(dǎo)入要導(dǎo)入的圖表的屬性更改，則原件將繼續(xù)執(zhí)行。一個例子是圖表頁腳。如果.ten文件未設(shè)置頁腳并且目標(biāo)圖表具有，則頁腳將在導(dǎo)入后通過圖表顯示。如果希望在導(dǎo)入圖表后對導(dǎo)入圖表進行更改可能會對所需結(jié)果產(chǎn)生負面影響，那么可以創(chuàng)建圖表的新實例，如下例所示：
[C#.Net]
private void Form1_Load(object sender, System.EventArgs e)
Bar bar1 = new Bar(tChart1.Chart);
bar1.FillSampleValues(20);
private void button1_Click(object sender, System.EventArgs e)
saveFileDialog1.Filter = "TenFile (.ten)|*.ten";
saveFileDialog1.ShowDialog();
if(saveFileDialog1.FileName != "")
tChart1.Export.Template.IncludeData = true;
tChart1.Export.Template.Save(saveFileDialog1.FileName);
private void button2_Click(object sender, System.EventArgs e)
tChart1.Dispose();
tChart1 = new Steema.TeeChart.TChart();
ini_Chart();
private void ini_Chart()
this.tChart1.Header.Lines = new string[] "TeeChart";
this.tChart1.Location = new System.Drawing.Point(24, 24);
this.tChart1.Name = "tChart1";
this.tChart1.Size = new System.Drawing.Size(400, 240);
this.tChart1.TabIndex = 5;
this.Controls.AddRange(new System.Windows.Forms.Control[] this.tChart1);
private void button3_Click(object sender, System.EventArgs e)
tChart1.Import.Template.LoadFileDialog();
[VB.Net]
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim Bar1 As New Steema.TeeChart.Styles.Bar(TChart1.Chart)
Bar1.FillSampleValues(20)
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
SaveFileDialog1.Filter = "TenFile (.ten)|*.ten"
SaveFileDialog1.ShowDialog()
If Not SaveFileDialog1.FileName = "" Then
TChart1.Export.Template.IncludeData = True
TChart1.Export.Template.Save(SaveFileDialog1.FileName)
End If
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
TChart1.Dispose()
TChart1 = New Steema.TeeChart.TChart()
Ini_Chart()
End Sub
Private Sub Ini_Chart()
Me.TChart1.Header.Lines = New String() "TeeChart"
Me.TChart1.Location = New System.Drawing.Point(16, 16)
Me.TChart1.Name = "TChart1"
Me.TChart1.Size = New System.Drawing.Size(400, 296)
Me.TChart1.TabIndex = 3
Me.Controls.AddRange(New System.Windows.Forms.Control() Me.TChart1)
End Sub
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
TChart1.Import.Template.LoadFileDialog()
End Sub
