[url=viewtopic.php?t=14917]Ich möchte[/url] die Zeichnung in Matplotlib in Pil wiederholen. Vielleicht ist das Problem, dass mein Datenformat "4,005.4.006" lautet. Wie erstelle ich die gleiche Grafik in Pil? < /P>
[code]from PIL import Image, ImageDraw

draw = ImageDraw.Draw(im)
for i in range(len(x)-1):

im.show()
# this is the graphic i want to get

Danke im Voraus
