php报表使用

php报表的使用：

1、到官网（http://jpgraph.net/）下载，建议下载jpgraph-3.0.7.tar.gz版本

2、解压后有两个文件夹

docportal：使用手册

src：报表核心文件

3、配置核心文件(对于src文件夹内容的操作)

1）创建一个jpgraph文件夹

2）将和Examples同级目录下的其它内容放在jpgraph文件夹下

3）将jpgraph放在Examples里

4）查找效果图。Examples里的每个php文件对应一个报表，可以在jpgraph11-3.0.7\docportal\chunkhtml\images查看报表的效果图，效果图的文件名和对应php文件的文件名相同

（如果你打开Examples文件夹里的某一个文件，你会发现有这样一句代码：require_once ('jpgraph/jpgraph.php')。但你却在该文件夹里没有找到jpgraph文件夹。其实jpgraph文件夹里的内容都放在和Examples同一目录下。因此你只要在Examples里创建一个jpgraph文件夹，并把和Examples同级目录的其它内容放到该文件夹里即可。）

4、引用方式：

1）直接访问php文件，如报表的效果图文件名为example27.1.png，则直接访问example27.1.php即可

2）作为图片引用，如<img alt="报表" src="example27.1.php" />

5、中文乱码处理

当你的文件为utf8时，会出现中文乱码，这时可使用iconv()将中文字符串转成gb2312。

例如：

$graph->title->Set(iconv("utf-8", "gb2312//ignore", "处理情况统计"));
$graph->title->SetFont(FF_SIMSUN,FS_BOLD);

具体详见：http://blog.csdn.net/ms_x0828/article/details/5555864

6、案例分析

1）柱形图1

代码：

 <?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);//多增加的数据

 // Create the graph.
 $graph = new Graph(650,450);//画布大小
 //$graph->SetScale('textlin');
 $graph->SetScale('textlin',-10,25);//设置y轴范围为5-75
 $graph->yaxis->scale->ticks->Set(5);//设置y轴刻度为10
 //$graph->xaxis->scale->ticks->Set(5);
 $graph->xaxis->title->Set("X轴");
 $graph->xaxis->title->SetFont(FF_SIMSUN,FS_BOLD,14);
 $graph->yaxis->title->Set("Y轴");
 $graph->yaxis->title->SetFont(FF_SIMSUN,FS_BOLD,14); 

 $graph->SetMarginColor('white');//设置边框背景颜色
 $graph->SetMargin(40,40,10,10);//设置图在边框中的位置

 // Setup title
 $graph->title->Set('Acc bar with gradient呵呵');//设置标题，默认的标题不支持中文
 $graph->title->SetFont(FF_SIMSUN,FS_BOLD,14);   //设置字体类型和大小。第一个参数决定是否能显示中文。参数值可参考jpgraph_ttf.inc.php文件

 // Create the first bar
 $bplot = new BarPlot($datay1);
 $bplot->SetFillGradient('AntiqueWhite2','AntiqueWhite4:0.8',GRAD_VERT);//设置柱体颜色
 //$bplot->SetFillgradient('orange','darkred',GRAD_VER); //设置柱体颜色
 $bplot->SetColor('orange');//柱体边界的颜色

 // Create the second bar
 $bplot2 = new BarPlot($datay2);
 $bplot2->SetFillGradient('olivedrab1','olivedrab4',GRAD_VERT);//柱体中增加部分的颜色
 $bplot2->SetColor('red');//柱体中增加部分的边框颜色

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

 $graph->Stroke();
 ?>

2）柱形图2
代码：

 <?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); //边框边界的颜色
 $graph->SetColor('lightblue');//柱体图背景颜色
 $graph->SetMarginColor('lightblue');//边框背景颜色

 // Setup X-axis labels
 $a = $gDateLocale->GetShortMonth();//x轴用月份显示
 $graph->xaxis->SetTickLabels($a);
 $graph->xaxis->SetFont(FF_FONT1);
 $graph->xaxis->SetColor('darkblue','black');//x轴的颜色

 // 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轴颜色
 $graph->ygrid->SetColor('white');//y轴分割线的颜色

 // Setup graph title ands fonts
 $graph->title->Set('Using grace = 0测试');
 $graph->title->SetFont(FF_SIMSUN,FS_BOLD);//FF_SIMSUN显示中文
 $graph->xaxis->SetTitle('Year 2002','center');
 $graph->xaxis->SetTitleMargin(10);//x轴标题显示的位置
 $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轴显示的最大的值

 // Create a bar pot
 $bplot = new BarPlot($datay);
 $bplot->SetFillColor('darkblue');//柱体填充的颜色
 $bplot->SetColor('darkblue');//柱体边框颜色
 $bplot->SetWidth(0.5);//设置柱体的宽度，取值：0~1
 $bplot->SetShadow('darkgray');//柱体阴影颜色

 /*显示和设置柱体上数字的样式*/
 $bplot->value->Show();
 $bplot->value->SetFont(FF_ARIAL,FS_NORMAL,9);//柱体上数字的字体和大小
 $bplot->value->SetFormat('$%d');//柱体上数字的格式
 $bplot->value->SetColor('darkred');//柱体上数字的颜色
 $bplot->value->SetAngle(45);//柱体上数字的倾斜度
 $graph->Add($bplot);

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

3）折线图

$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');//标题
$graph->subtitle->Set('(March 12, 2008)');//副标题
$graph->xaxis->title->Set('Operator x轴');
$graph->yaxis->title->Set('# of calls y轴');

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

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