This example demonstrates the basic steps in creating bar charts.
[Standalone Version] pythondemo\simplebar.py

from pychartdir import *
# The data for the bar chart
data = [85, 156, 179.5, 211, 123]
# The labels for the bar chart
labels = ["Mon", "Tue", "Wed", "Thu", "Fri"]
# Create a XYChart object of size 250 x 250 pixels
c = 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 labels on the x axis.
c.xAxis().setLabels(labels)
# Output the chart
