软件介绍
PHPLOT 是一个用来创建图表的PHP图形类，需要 PHP5 的支持。PHPLot使用PHP的GD扩展来生成 PNG/GIF/JPEG 格式图片。
生成上面图形的代码如下：
# PHPlot Demo
# 2008-01-09 ljb
# For more information see http://sourceforge.net/projects/phplot/
# Load the PHPlot class library:
require_once 'phplot.php';
# Define the data array: Label, the 3 data sets.
# Year, Features, Bugs, Happy Users:
$data = array(
array('2001', 60, 35, 20),
array('2002', 65, 30, 30),
array('2003', 70, 25, 40),
array('2004', 72, 20, 60),
array('2005', 75, 15, 70),
array('2006', 77, 10, 80),
array('2007', 80, 5, 90),
);
# Create a PHPlot object which will make a 600x400 pixel image:
$p = new PHPlot(600, 400);
# Use TrueType fonts:
$p->SetDefaultTTFont('./arial.ttf');
# Set the main plot title:
$p->SetTitle('PHPlot Customer Satisfaction (estimated)');
# Select the data array representation and store the data:
$p->SetDataType('text-data');
$p->SetDataValues($data);
# Select the plot type - bar chart:
$p->SetPlotType('bars');
# Define the data range. PHPlot can do this automatically, but not as well.
$p->SetPlotAreaWorld(0, 0, 7, 100);
# Select an overall image background color and another color under the plot:
$p->SetBackgroundColor('#ffffcc');
$p->SetDrawPlotAreaBackground(True);
$p->SetPlotBgColor('#ffffff');
# Draw lines on all 4 sides of the plot:
$p->SetPlotBorderType('full');
# Set a 3 line legend, and position it in the upper left corner:
$p->SetLegend(array('Features', 'Bugs', 'Happy Users'));
$p->SetLegendWorld(0.1, 95);
# Turn data labels on, and all ticks and tick labels off:
$p->SetXDataLabelPos('plotdown');
$p->SetXTickPos('none');
$p->SetXTickLabelPos('none');
$p->SetYTickPos('none');
$p->SetYTickLabelPos('none');
# Generate and output the graph now:
$p->DrawGraph();
