[Django]-Adding Graph to Reportlab PDF

skip the canvas and just use the Drawing widget- it will generate the PDF:

d = Drawing(200, 100)
pc = Pie()
pc.x = 65
pc.y = 15
pc.width = 70
pc.height = 70
pc.data = [10,20,30,40,50,60]
pc.labels = ['a','b','c','d','e','f']
pc.slices.strokeWidth=0.5
pc.slices[3].popout = 10
pc.slices[3].strokeWidth = 2
pc.slices[3].strokeDashArray = [2,2]
pc.slices[3].labelRadius = 1.75
pc.slices[3].fontColor = colors.red
d.add(pc)

d.save(formats=['pdf'],outDir=None,fnRoot='C:/test')

If you need to add the chart to your canvas use d.drawOn(p,0,0) instead of p.drawPath(d)

An improved answer from @siguy example, using reportlab 2.7.

from reportlab.lib.colors import red
from reportlab.graphics.shapes import Drawing
from reportlab.graphics.charts.piecharts import Pie

def savePdfGraph(request):
    d = Drawing(width=400, height=200)
    pc = Pie()
    pc.x = 150
    pc.y = 50
    pc.width = 70
    pc.height = 70
    pc.data = [10, 20, 30, 40, 50, 60]
    pc.labels = ['a', 'b', 'c', 'd', 'e', 'f']
    pc.slices.strokeWidth = 0.5
    pc.slices[3].popout = 10
    pc.slices[3].strokeWidth = 2
    pc.slices[3].strokeDashArray = [2, 2]
    pc.slices[3].labelRadius = 1.75
    pc.slices[3].fontColor = red
    d.add(pc)

    filename = 'test'
    base_dir = '/home/'
    path = os.path.join(base_dir, filename)
    d.save(formats=['pdf'], outDir=None, fnRoot=path)
    return redirect('/')
