This example extends the
Simple Bar Chart example by introducing three more features of ChartDirector:
[File: perldemo/threedbar.pl] (The CGI version is available as "perldemo_cgi/threedbar.pl".)
#!/usr/bin/perl
use perlchartdir;
#The data for the bar chart
my $data = [85, 156, 179.5, 211, 123];
#The labels for the bar chart
my $labels = ["Mon", "Tue", "Wed", "Thu", "Fri"];
#Create a XYChart object of size 300 x 280 pixels
my $c = new XYChart(300, 280);
#Set the plotarea at (45, 30) and of size 200 x 200 pixels
$c->setPlotArea(45, 30, 200, 200);
#Add a title to the chart
$c->addTitle("Weekly Server Load");
#Add a title to the y axis
$c->yAxis()->setTitle("MBytes");
#Add a title to the x axis
$c->xAxis()->setTitle("Work Week 25");
#Add a bar chart layer with green (0x00ff00) bars using the given data
$c->addBarLayer($data, 0xff00)->set3D();
#Set the x axis labels using the given labels
$c->xAxis()->setLabels($labels);
#output the chart
$c->makeChart("threedbar.png")
