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);

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->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
