Hi,
I am having trouble graphing constant functions in matplotlib (a simple
y = 2). Here is a simple test script I'm using:
from pylab import *
def f(x):
return 2
x = arange(1, 4)
plot(x, f(x))
show()
When I run it, I get this error:
Traceback (most recent call last):
File "test", line 8, in ?
plot(x, f(x))
File "/usr/lib/python2.4/site-packages/matplotlib/pylab.py", line
2019, in plot
ret = gca().plot(*args, **kwargs)
File "/usr/lib/python2.4/site-packages/matplotlib/axes.py", line 2106,
in plot
for line in self._get_lines(*args, **d):
File "/usr/lib/python2.4/site-packages/matplotlib/axes.py", line 304,
in _grab_next_args
yield self._plot_2_args(remaining, **kwargs)
File "/usr/lib/python2.4/site-packages/matplotlib/axes.py", line 253,
in _plot_2_args
assert(iterable(y))
AssertionError
Could anyone tell me what I'm doing wrong (I'm new to matplotlib btw)?
Thanks!
