### 一、pChart（http://pchart.sourceforge.net）

1.pChart.class（圖表物件檔）、pData.class（資料物件檔）、pCache.class（快取物件檔）

include\_once("pChart/pData.class"); 
 include\_once("pChart/pChart.class");

### 二、匯入資料的二種方式：

1.直接寫在程式中：AddPoint($資料值,$資料組名稱="Serie1",$資料組說明="")

$DataSet = new pData; 
 $DataSet->AddPoint(array(128673,2889,1376,830,170),"count","造訪次數"); 
 $DataSet->AddPoint(array("台灣","香港","中國","美國","德國"),"country","國家"); 
 $DataSet->AddAllSeries(); 
 $DataSet->SetAbsciseLabelSerie();

2.從CSV檔匯入：ImportFromCSV($CSV檔來源,$分隔符=",",$資料從第幾欄開始=-1,$是否有標題=FALSE,$當作標籤的是第幾欄=-1)

$DataSet->ImportFromCSV("Sample/ck2.csv",",",array(3),TRUE,0);

### 三、繪製圖表

1.產生圖表物件：new pChart(寬,高);

2.設定標記字型；setFontProperties("字型",大小);

3.設定繪圖區域：setGraphArea($X1,$Y1,$X2,$Y2) ;

4.繪製圖表：drawScale($Data,$DataDescription,$模式,$R,$G,$B,$顯示標籤=TRUE,$X軸標籤角度=0,$小數幾位=1,$圖在邊界內=FALSE,$略過幾個標籤=1,$RightScale=FALSE)

(1) SCALE\_NORMAL：取得資料組的最大和最小值  
 (2) SCALE\_START0：最小值從0開始  
 (3) SCALE\_ADDALL：取得資料組累積的最大和最小值  
 (4) SCALE\_ADDALLSTART0：取得資料組累積的最大值，最小從0開始

5.繪製標線：drawGrid($LineWidth,$Mosaic=TRUE,$R=220,$G=220,$B=220,$Alpha=255)

$Test = new pChart(700,230); 
 $Test->setFontProperties("Fonts/cwyen.ttf",8); 
 $Test->setGraphArea(50,30,680,200); 
 $Test->drawScale($DataSet->GetData(),$DataSet->GetDataDescription(),SCALE\_NORMAL,150,150,150,TRUE,0,2,TRUE); 
 $Test->drawGrid(4,TRUE,230,230,230,50);

6.長條圖：drawBarGraph($Data,$DataDescription,$陰影=FALSE)

7.曲線圖：drawCubicCurve($Data,$DataDescription,$圓滑度)

8.折線圖：drawLineGraph($Data,$DataDescription)

9.點圖：drawPlotGraph(&$Data,&$DataDescription,$大半徑=5,$小半徑=2,$R2=-1,$G2=-1,$B2=-1,$陰影=FALSE)

10.圓餅圖：drawPieGraph($Data,$DataDescription,$X,$Y,$半徑,$繪製標籤=PIE\_NOLABEL,$加強顏色=TRUE,$透視角度=60,$高度=20,$分開距離=0,$小數幾位=0)

$Test->drawBarGraph($DataSet->GetData(),$DataSet->GetDataDescription(),TRUE);

11.繪製說明表：drawLegend($X,$Y,$DataDescription,$R,$G,$B,$Rs=-1,$Gs=-1,$Bs=-1,$Rt=0,$Gt=0,$Bt=0,$邊框=FALSE)

$Test->drawLegend(350,50,$DataSet->GetDataDescription(),255,255,255);

12.產生圖片Render("$檔名");

$Test->Render("demo1.png");

### 四、網頁或PHP使用：

echo "<img src='demo1.png'>";
