## Overview

Python has its drawing API very similar to PIL. Porting from PIL to S60 is very easy. Here's an example for porting a sparkline drawing function from Joe Gregorio's article at xml.com

## Code

`# import modulesfrom appuifw import *import e32 lock = e32.Ao_lock()  # declare exit lockc = Canvas()app.body = cdraw = c._draw # define colorsred, green, blue, gray = 0xff0000, 0x00ff00, 0x0000ff, 0x777777 def plot_sparkline(results, step=2, height=20, \    min_m=None, max_m=None, last_m=None, \    min_color=blue, max_color=green, last_color=red):    coords = zip(range(1,len(results)*step+1, step), \       [height - 3  - y/(101.0/(height-4)) for y in results])    draw.line(coords, gray)    if min_m:        min_pt = coords[results.index(min(results))]        draw.rectangle([min_pt[0]-1, min_pt[1]-1, min_pt[0]+1, min_pt[1]+1], fill=min_color)    if max_m:        max_pt = coords[results.index(max(results))]        draw.rectangle([max_pt[0]-1, max_pt[1]-1, max_pt[0]+1, max_pt[1]+1], fill=max_color)    if last_m:        end = coords[-1]        draw.rectangle([end[0]-1, end[1]-1, end[0]+1, end[1]+1], fill=last_color)  results = [88,84,82,92,82,86,66,82,44,64,66,88,96,80,24,26, \        14,0,0,26,8,6,6,24,52,66,36,6,10,14,30]plot_sparkline(results, 3, 30, min_m=1, max_m=1, last_m=1) app.exit_key_handler = lock.signallock.wait() # Wait for exit`
