This example demonstrates the basic steps in creating pyramid charts.
[Standalone Version] pythondemo\simplepyramid.py
#!/usr/bin/python
from pychartdir import *
# The data for the pyramid chart
data = [156, 123, 211, 179]
# The labels for the pyramid chart
labels = ["Funds", "Bonds", "Stocks", "Cash"]
# Create a PyramidChart object of size 360 x 360 pixels
c = PyramidChart(360, 360)
# Set the pyramid center at (180, 180), and width x height to 150 x 180 pixels
c.setPyramidSize(180, 180, 150, 300)
# Set the pyramid data and labels
c.setData(data, labels)
# Add labels at the center of the pyramid layers using Arial Bold font. The labels
# will have two lines showing the layer name and percentage.
c.setCenterLabel("{label}\n{percent}%", "arialbd.ttf")
# Output the chart
