In web2py+matplotlib:
def simple():
import random, cStringIO
from matplotlib.backends.backend_agg import FigureCanvasAgg as
FigureCanvas
from matplotlib.figure import Figure
from matplotlib.dates import DateFormatter
fig=Figure()
ax=fig.add_subplot(111)
x=[]
y=[]
now=datetime.datetime.now()
delta=datetime.timedelta(days=1)
for i in range(10):
x.append(now)
now+=delta
y.append(random.randint(0, 1000))
ax.plot_date(x, y, '-')
ax.xaxis.set_major_formatter(DateFormatter('%Y-%m-%d'))
fig.autofmt_xdate()
canvas=FigureCanvas(fig)
response.header['content-type']='image/png'
stream=cStringIO.StringIO()
canvas.print_png(stream)
return stream.getvalue()
