ChartDirector Ver 3.0 (Perl Edition)

The First Project




To get a feeling of the ChartDirector, and to verify the ChartDirector development environment is set up properly, we will begin by building a very simple bar chart.

If you have not yet installed the sample programs, it is highly recommended you install them now. Please refer to the Installation section for details. They are very useful for exploring and testing the features of ChartDirector.

[The following is available as "perldemo/simplebar.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 250 x 250 pixels my $c = new XYChart(250, 250); #Set the plotarea at (30, 20) and of size 200 x 200 pixels $c->setPlotArea(30, 20, 200, 200); #Add a bar chart layer using the given data $c->addBarLayer($data); #Set the x axis labels using the given labels $c->xAxis()->setLabels($labels); #output the chart $c->makeChart("simplebar.png")

The code is explained below:

Note: If you are running ChartDirector on Linux/FreeBSD/Solaris, the charts produced may be slightly different from the chart samples in this documentation, which are produced under Windows. This is because of the different fonts available on Windows and Linux/FreeBSD/Solaris. Please refer to Font Specification on why you may want to download Windows fonts to be used on Linux/FreeBSD/Solaris.

Note: The trial version of ChartDirector will include small yellow banners at the bottom of the charts it produces. These banners will disappear in the licensed version of ChartDirector.
