Great thanks...
I found this function... it seems complicated, but it is kind of
working... I hope that I can include it in a my web page...
# file charts.pydef simple(request): import random import django
import datetime 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=django.http.HttpResponse(content_type='image/png')
canvas.print_png(response) return response
