This example demonstrates using
PieChart.set3D2 to create a 3D pie chart where sectors have different 3D heights.
[File: pythondemo/multidepthpie.py] (The CGI version is available as "pythondemo_cgi/multidepthpie.py".)
#!/usr/bin/python
from pychartdir import *
#The data for the pie chart
data = [72, 18, 15, 12]
#The labels for the pie chart
labels = ["Labor", "Machinery", "Facilities", "Computers"]
#The depths for the sectors
depths = [30, 20, 10, 10]
#Create a PieChart object of size 360 x 300 pixels, with a light blue (0xccccff)
#background and a 1 pixel 3D border
c = PieChart(360, 300, 0xccccff, -1, 1)
#Set the center of the pie at (180, 175) and the radius to 100 pixels
c.setPieSize(180, 175, 100)
#Add a title box using Times Bold Italic/14 points as font and 0x9999ff as
#background color
c.addTitle("Project Cost Breakdown", "timesbi.ttf", 14).setBackground(0x9999ff)
#Set the pie data and the pie labels
c.setData(data, labels)
#Draw the pie in 3D
c.set3D2(depths)
#Set the start angle to 225 degrees may improve layout when the depths of the
#sector are sorted in descending order, because it ensures the tallest sector is
#at the back.
c.setStartAngle(225)
#output the chart
c.makeChart("multidepthpie.png")
