在JpGraph循环中包含多个图形的for

Question

我正在尝试通过使用JpGraph的for循环来创建年度和月度图。我读到每个图只能实例化一次，并且在for循环开始之前通过实例化图来编写代码来适应这一点。在调用Stroke()之后，代码将只生成一个图形，并且不会创建更多的图形。有什么想法吗？

Answer 1

1. 创建一个包含所有图形的常规html文件。
2. 手动使用img标记或使用php循环

调用每个图形

当您使用img标记来src jpgraph的url时，带描边的图形将被视为图像。这样，您可以在每个页面上有多个图形，并将每个图形的代码分开。

Answer 2

这是旧的，但我偶然发现它寻找答案如何添加多个jpgraph csim图像到一个页面。

基于jpgraph示例，我的成功步骤是使用以下文件(display.php)，该文件使用在单独的图像脚本($_graphfilename1、$_graphfilename2)中创建的CSIM来显示多个图形。要显示两个图形，您需要三个单独的脚本，即两个图像脚本和组合显示的脚本。

在jpgraph文档示例中不清楚的关键是，两个图像脚本中的每一个都必须使用不同的变量名，例如$graph变量的$graph1、$graph2，并相应地描边，然后在display.php脚本中适当地引用这些变量

    <?php

// The names of the graph scripts
$_graphfilename1 = 'projectcsim.php';
$_graphfilename2 = 'resultcsim.php';

// This is the filename of this HTML file
global $_wrapperfilename;
$_wrapperfilename = basename (__FILE__);

// Create a random mapname used to connect the image map with the image
$_mapname1 = '__mapname'.rand(0,1000000).'__';
$_mapname2 = '__mapname'.rand(0,1000000).'__';

// Get the graph scripts
require_once ($_graphfilename1);
require_once ($_graphfilename2);

// This line gets the image map and inserts it on the page
$imgmap1 = $graph1->GetHTMLImageMap($_mapname1);
$imgmap2 = $graph2->GetHTMLImageMap($_mapname2);
echo $imgmap1;
echo $imgmap2;

// Construct the <img> tags for Figure 1 &amp; 2 and rebuild the URL arguments
$imgtag1 = $graph1->GetCSIMImgHTML($_mapname1,$_graphfilename1);
$imgtag2 = $graph2->GetCSIMImgHTML($_mapname2,$_graphfilename2);
?>
<table border=0>
<tr><td valign="bottom">
<?php
echo $imgtag1;
?>
<br><b>Figure 1. </b>
</td></tr><tr>
<td valign="bottom">
<?php
echo $imgtag2;
?>
<br><b>Figure 2. </b>
</td>
</tr>
