PHPChart如何导出到pdf，和图片？

Question

我正在使用PHPChart创建图表，现在我想有一个导出图表到pdf和图像的选项。下面是我的代码：

<link rel="stylesheet" type="text/css" href="/phpChart_Enterprise/js/src/jquery.jqplot.css" />
<!--<link rel="stylesheet" type="text/css" href="/phpChart_Enterprise/examples/examples.css" />-->
<!--[if lt IE 7]>
<script type="text/javascript" src="../../flot/excanvas.js"></script>
<![endif]-->
<!--[if lt IE 7]>
<script type="text/javascript" src="../../explorercanvas/excanvas.js"></script>
<![endif]-->
<!--[if lt IE 9]>
<script type="text/javascript" src="/phpChart_Enterprise/js/src/excanvas.js"></script>
<![endif]-->
<!--[if lt IE 7]>
<script type="text/javascript" src="../../flashcanvas/src/flashcanvas.js"></script>
<![endif]-->

<!-- BEGIN: load jquery -->
<script language="javascript" type="text/javascript" src="/phpChart_Enterprise/js/src/jquery.js"></script>

<!-- BEGIN: load jqplot -->
<script language="javascript" type="text/javascript" src="/phpChart_Enterprise/js/src/jquery.jqplot.js"></script>
<script language="javascript" type="text/javascript" src="/phpChart_Enterprise/js/src/plugins/jqplot.categoryAxisRenderer.js"></script>
<script language="javascript" type="text/javascript" src="/phpChart_Enterprise/js/src/plugins/jqplot.dateAxisRenderer.js"></script>
<script language="javascript" type="text/javascript" src="/phpChart_Enterprise/js/src/plugins/jqplot.barRenderer.js"></script>
<script language="javascript" type="text/javascript" src="/phpChart_Enterprise/js/src/plugins/jqplot.canvasAxisTickRenderer.js">   </script>
 <script language="javascript" type="text/javascript" src="/phpChart_Enterprise/js/src/plugins/jqplot.canvasTextRenderer.js"></script>
  <!--<script language="javascript" type="text/javascript" src="/phpChart_Enterprise/js/src/canvasHack2.js"></script>-->
<script type="text/javascript">
$(document).ready(function(){

    if (!$.jqplot.use_excanvas) {
        $('div.jqplot-target').each(function(){
            // Add a view image button
            var btn = $(document.createElement('button'));
            btn.text('View as PNG');
            btn.bind('click', {chart: $(this)}, function(evt) {
                evt.data.chart.jqplotViewImage();
            });
            $(this).after(btn);

            // add a save image button
            btn = $(document.createElement('button'));
            btn.text('Save as PNG');
            btn.bind('click', {chart: $(this)}, function(evt) {
                evt.data.chart.jqplotSaveImage();
            });
            $(this).after(btn);
            btn = null;
        });
    }

    $('#stackChart1').CanvasHack();
});
</script>

但是当我点击生成的按钮时，Save as PNG和View AS PNG浏览器就会进入加载和下载状态。

感谢任何帮助和guid。

你看过图片导出的例子了吗？这一切都是用Javascript完成的。

不确定PDF导出，但我相信这将需要一些服务器端脚本。请参见下面的示例。
