pieChartΒΆ
A pie chart (or a circle graph) is a circular chart divided into sectors, illustrating numerical proportion. In chart, the arc length of each sector is proportional to the quantity it represents.
Django example:
from django.shortcuts import render_to_response
import random
import datetime
import time
def demo_piechart(request):
"""
pieChart page
"""
xdata = ["Apple", "Apricot", "Avocado", "Banana", "Boysenberries", "Blueberries", "Dates", "Grapefruit", "Kiwi", "Lemon"]
ydata = [52, 48, 160, 94, 75, 71, 490, 82, 46, 17]
extra_serie = {"tooltip": {"y_start": "", "y_end": " cal"}}
chartdata = {'x': xdata, 'y1': ydata, 'extra1': extra_serie}
charttype = "pieChart"
data = {
'charttype': charttype,
'chartdata': chartdata,
}
return render_to_response('piechart.html', data)
