[Matplotlib-users] x and y axis through (0,0)

[David C. <dc...@ce...>]

Hello,=20

Thanks very much for matplotlib its fast becoming the main tool I use for =
plotting!
I'm fairly new to matplotlib so apologies if this seems like an obvious =
question. I'm plotting a fairly standard scatter plot using plot.=20
something like....=20

plot(x,y,'kx')=20

and my data is normalised so ([-1,1],[-1,1]).=20

How can I create a plot with x and y axis (inc ticks and labels) through =
the origin (0,0)?

Many thanks for any help

this is very similar to what i wanted to do in a recent
post, see the thread titled "gridlines at 0,0 only",
http://sourceforge.net/mailarchive/message.php?msg_id=12231581

the short version of it:

   props = dict(color="black", linestyle="--", linewidth=1)
   axvline(x=0, **props) 
   axhline(y=0, **props)


thanks for asking, it would be a nice feature to have this
as a stand-alone option for plot() or grid() commands.
