This example extends the
Simple Pie Chart example by introducing three more features of ChartDirector:
[File: perldemo/threedpie.pl] (The CGI version is available as "perldemo_cgi/threedpie.pl".)
#!/usr/bin/perl
use perlchartdir;
#The data for the pie chart
my $data = [25, 18, 15, 12, 8, 30, 35];
#The labels for the pie chart
my $labels = ["Labor", "Licenses", "Taxes", "Legal", "Insurance", "Facilities",
"Production"];
#Create a PieChart object of size 360 x 300 pixels
my $c = new PieChart(360, 300);
#Set the center of the pie at (180, 140) and the radius to 100 pixels
$c->setPieSize(180, 140, 100);
#Add a title to the pie chart
$c->addTitle("Project Cost Breakdown");
#Draw the pie in 3D
$c->set3D();
#Set the pie data and the pie labels
$c->setData($data, $labels);
#Explode the 1st sector (index = 0)
$c->setExplode(0);
#output the chart
$c->makeChart("threedpie.png")
