This example demonstrates the following ChartDirector features:
[File: pythondemo/legendpie.py] (The CGI version is available as "pythondemo_cgi/legendpie.py".)
#!/usr/bin/python
from pychartdir import *
#The data for the pie chart
data = [25, 18, 15, 12, 8, 30, 35]
#The labels for the pie chart
labels = ["Labor", "Licenses", "Taxes", "Legal", "Insurance", "Facilities",
"Production"]
#Create a PieChart object of size 450 x 240 pixels
c = PieChart(450, 240)
#Set the center of the pie at (150, 100) and the radius to 80 pixels
c.setPieSize(150, 100, 80)
#Add a title at the bottom of the chart using Arial Bold Italic font
c.addTitle2(Bottom, "Project Cost Breakdown", "arialbi.ttf")
#Draw the pie in 3D
c.set3D()
#add a legend box where the top left corner is at (330, 40)
c.addLegend(330, 40)
#modify the label format for the sectors to $nnnK (pp.pp%)
c.setLabelFormat("{label} ${value}K\n({percent}%)")
#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("legendpie.png")
