You can try the following approach: First plot the line and then plot
the markers separately (and set colors).
x = linspace(0,10,100)
y = x
plot(x, y, '-')
plot(x[::10], y[::10], linestyle

Hi Florian,
you should try "import pylab" or "import pylab as P". "from pylab
import *" might overwrite some functions or methods ... if a pylab
function/method has the same name as one in a module imported with * before.
See the following example:
#file a.py
def foo():
print "I'm a"

Hi,
you are limited to 10 "named" symbols. But you can use much more symbols
with scatter !!! Have a look at examples/scatter_star_symbols.py.
You can use:
pylab.scatter(x,y,marker=(5,0))
produces a 5-sided regular polygon.
pylab.scatter(x,y,marker=(5,1))
produces a starlike polygon

It seems that the keywords facecolor (or color) and alpha can not be
used simultaniously when using "scatter":
import pylab

pylab.scatter(x,x, s=50, alpha=0.5)
