REQUIREMENTS:
|
|
|
|
You need a recent version of PHP: 4.3.0 or higher. You are advised to use
|
|
the latest stable release of PHP 4. (Testing with PHP 5 is not complete
|
|
at this time.)
|
|
|
|
You need the GD extension to PHP either built in to PHP or loaded as a
|
|
module. Refer to the PHP documentation for more information - see the
|
|
Image Functions chapter in the PHP Manual.
|
|
|
|
If you want to display PHPlot charts on a web site, you need a PHP-enabled
|
|
web server. You can also use the PHP CLI interface without a web server.
|
|
|
|
If you want to use TrueType fonts on your charts, you need to have TrueType
|
|
support in GD, and some TrueType font files. PHPlot does not include any
|
|
TrueType font files. By default, PHPlot uses a simple built-in font.
|
|
|
|
|
|
INSTALLATION:
|
|
|
|
Unpack the distribution. (If you are reading this file, you have probably
|
|
already done that.)
|
|
|
|
Installation of PHPlot simply involves copying three script files somewhere
|
|
your PHP application scripts will be able to find them. The scripts are:
|
|
phplot.php
|
|
phplot_data.php
|
|
rgb.inc.php
|
|
(Only phplot.php is necessary for most graphs.)
|
|
Make sure the protections on these files allow the web server to read them.
|
|
|
|
The ideal place is a directory outside your web server document area,
|
|
and on your PHP include path. You can add to the include path in the PHP
|
|
configuration file; consult the PHP manual for details.
|
|
|
|
|
|
|
|
TESTING:
|
|
|
|
You can test your installation by creating the following two files somewhere
|
|
in your web document area. First, the HTML file:
|
|
|
|
------------ simpleplot.html ----------------------------
|
|
<html>
|
|
<head>
|
|
<title>Hello, PHPlot!</title>
|
|
</head>
|
|
<body>
|
|
<h1>PHPlot Test</h1>
|
|
<img src="simpleplot.php">
|
|
</body>
|
|
</html>
|
|
---------------------------------------------------------
|
|
|
|
Second, in the same directory, the image file producing PHP script file.
|
|
Depending on where you installed phplot.php, you may need to specify a path
|
|
in the 'require' line below.
|
|
|
|
------------ simpleplot.php -----------------------------
|
|
<?php
|
|
require 'phplot.php';
|
|
$plot =& new PHPlot();
|
|
$data = array(array('', 0, 0), array('', 1, 9));
|
|
$plot->SetDataValues($data);
|
|
$plot->SetDataType('data-data');
|
|
$plot->DrawGraph();
|
|
---------------------------------------------------------
|
|
|
|
Access the URL to 'simpleplot.html' in your web browser. If you see a
|
|
simple graph, you have successfully installed PHPlot. If you see no
|
|
graph, check your web server error log for more information.
