php報表使用

php報表的使用：

1、到官網（http://jpgraph.net/）下載，建議下載jpgraph-3.0.7.tar.gz版本

2、解壓后有兩個文件夾

docportal：使用手冊

src：報表核心文件

3、配置核心文件(對於src文件夾內容的操作)

1）創建一個jpgraph文件夾

2）將和Examples同級目錄下的其它內容放在jpgraph文件夾下

3）將jpgraph放在Examples里

4）查找效果圖。Examples里的每個php文件對應一個報表，可以在jpgraph11-3.0.7\docportal\chunkhtml\images查看報表的效果圖，效果圖的文件名和對應php文件的文件名相同

（如果你打開Examples文件夾里的某一個文件，你會發現有這樣一句代碼：require_once ('jpgraph/jpgraph.php')。但你卻在該文件夾里沒有找到jpgraph文件夾。其實jpgraph文件夾里的內容都放在和Examples同一目錄下。因此你只要在Examples里創建一個jpgraph文件夾，並把和Examples同級目錄的其它內容放到該文件夾里即可。）

4、引用方式：

1）直接訪問php文件，如報表的效果圖文件名為example27.1.png，則直接訪問example27.1.php即可

2）作為圖片引用，如<img alt="報表" src="example27.1.php" />

5、中文亂碼處理

當你的文件為utf8時，會出現中文亂碼，這時可使用iconv()將中文字符串轉成gb2312。

例如：

$graph->title->Set(iconv("utf-8", "gb2312//ignore", "處理情況統計"));
$graph->title->SetFont(FF_SIMSUN,FS_BOLD);

具體詳見：http://blog.csdn.net/ms_x0828/article/details/5555864

6、案例分析

1）柱形圖1

代碼：

<?php // content="text/plain; charset=utf-8"
require_once ('jpgraph/jpgraph.php');
require_once ('jpgraph/jpgraph_bar.php');


$datay1=array(13,8,19);
$datay2=array(3,0,0);//多增加的數據

// Create the graph.
$graph = new Graph(650,450);//畫布大小
//$graph->SetScale('textlin');
$graph->SetScale('textlin',-10,25);//設置y軸范圍為5-75
$graph->yaxis->scale->ticks->Set(5);//設置y軸刻度為10
//$graph->xaxis->scale->ticks->Set(5);
$graph->xaxis->title->Set("X軸");
$graph->xaxis->title->SetFont(FF_SIMSUN,FS_BOLD,14); 
$graph->yaxis->title->Set("Y軸");
$graph->yaxis->title->SetFont(FF_SIMSUN,FS_BOLD,14); 

$graph->SetMarginColor('white');//設置邊框背景顏色
$graph->SetMargin(40,40,10,10);//設置圖在邊框中的位置

// Setup title
$graph->title->Set('Acc bar with gradient呵呵');//設置標題，默認的標題不支持中文
$graph->title->SetFont(FF_SIMSUN,FS_BOLD,14);   //設置字體類型和大小。第一個參數決定是否能顯示中文。參數值可參考jpgraph_ttf.inc.php文件

// Create the first bar
$bplot = new BarPlot($datay1);
$bplot->SetFillGradient('AntiqueWhite2','AntiqueWhite4:0.8',GRAD_VERT);//設置柱體顏色
//$bplot->SetFillgradient('orange','darkred',GRAD_VER); //設置柱體顏色
$bplot->SetColor('orange');//柱體邊界的顏色

// Create the second bar
$bplot2 = new BarPlot($datay2);
$bplot2->SetFillGradient('olivedrab1','olivedrab4',GRAD_VERT);//柱體中增加部分的顏色
$bplot2->SetColor('red');//柱體中增加部分的邊框顏色


// And join them in an accumulated bar
$accbplot = new AccBarPlot(array($bplot,$bplot2));
$graph->Add($accbplot);

$graph->Stroke();
?>

 

 

2）柱形圖2
代碼：

<?php // content="text/plain; charset=utf-8"
require_once ('jpgraph/jpgraph.php');
require_once ('jpgraph/jpgraph_bar.php');

// Some data
$datay=array(7,19,11,4,20);

// Create the graph and setup the basic parameters 
$graph = new Graph(600,500,'auto');    
$graph->img->SetMargin(40,30,40,50);
$graph->SetScale("textint");
$graph->SetFrame(true,'blue',1); //邊框邊界的顏色
$graph->SetColor('lightblue');//柱體圖背景顏色
$graph->SetMarginColor('lightblue');//邊框背景顏色

// Setup X-axis labels
$a = $gDateLocale->GetShortMonth();//x軸用月份顯示
$graph->xaxis->SetTickLabels($a);
$graph->xaxis->SetFont(FF_FONT1);
$graph->xaxis->SetColor('darkblue','black');//x軸的顏色

// Setup "hidden" y-axis by given it the same color
// as the background (this could also be done by setting the weight
// to zero)
$graph->yaxis->SetColor('lightblue','darkblue');//y軸顏色
$graph->ygrid->SetColor('white');//y軸分割線的顏色

// Setup graph title ands fonts
$graph->title->Set('Using grace = 0測試');
$graph->title->SetFont(FF_SIMSUN,FS_BOLD);//FF_SIMSUN顯示中文
$graph->xaxis->SetTitle('Year 2002','center');
$graph->xaxis->SetTitleMargin(10);//x軸標題顯示的位置
$graph->xaxis->title->SetFont(FF_FONT2,FS_BOLD);

// Add some grace to the top so that the scale doesn't
// end exactly at the max value. 
$graph->yaxis->scale->SetGrace(0);//修改y軸顯示的最大的值

                              
// Create a bar pot
$bplot = new BarPlot($datay);
$bplot->SetFillColor('darkblue');//柱體填充的顏色
$bplot->SetColor('darkblue');//柱體邊框顏色
$bplot->SetWidth(0.5);//設置柱體的寬度，取值：0~1
$bplot->SetShadow('darkgray');//柱體陰影顏色


/*顯示和設置柱體上數字的樣式*/
$bplot->value->Show();
$bplot->value->SetFont(FF_ARIAL,FS_NORMAL,9);//柱體上數字的字體和大小
$bplot->value->SetFormat('$%d');//柱體上數字的格式
$bplot->value->SetColor('darkred');//柱體上數字的顏色
$bplot->value->SetAngle(45);//柱體上數字的傾斜度
$graph->Add($bplot);

// Finally stroke the graph
$graph->Stroke();
?>

 

3）折線圖

代碼：

require_once ('jpgraph/jpgraph.php');
require_once ('jpgraph/jpgraph_line.php');

// Some (random) data
$ydata = array(11.1,3,8,12,5,1,9,13,5,7);

// Size of the overall graph
$width=650;
$height=550;

// Create the graph and set a scale.
// These two calls are always required
$graph = new Graph($width,$height);
$graph->SetScale('intlin');
$graph->SetShadow();

// Setup margin and titles
$graph->SetMargin(40,20,20,40);
$graph->title->Set('Calls per operator');//標題
$graph->subtitle->Set('(March 12, 2008)');//副標題
$graph->xaxis->title->Set('Operator x軸');
$graph->yaxis->title->Set('# of calls y軸');

$graph->yaxis->title->SetFont( FF_SIMSUN , FS_BOLD );
$graph->xaxis->title->SetFont( FF_SIMSUN , FS_BOLD );

$graph->yaxis->SetColor('blue');

// 折線
$lineplot=new LinePlot($ydata);
$lineplot->SetColor( 'blue' );
$lineplot->SetWeight( 2 );   // 折線圖顏色
$lineplot->mark->SetType(MARK_UTRIANGLE);

/*折線處的標記*/
$lineplot->mark->SetColor('blue');
$lineplot->mark->SetFillColor('red');

$lineplot->value->Show();//在折線處顯示數據

// Add the plot to the graph
$graph->Add($lineplot);

// Display the graph
$graph->Stroke();
