matplotlib-users Mailing List for matplotlib

Hi Pengkui,
I guess you're referring to something like:
In [15]: plot(np.arange(0,100,2),'D-',color='k',ms=3)
Out[15]: [<matplotlib.lines.Line2D at 0xbaaba8c>]
then it looks like it's a linestyle, but actually it's a combination of
marker and line, unlike the dash '--' or dots ':' which are pure
linestyles. because my data are quite dense, so I guess if I want to use
this way, I need to sample the data by a proper interval
to have this effect. which is also nice, for sure.
cheers,
Chao

Yes. it works fine. The only problem is that I would like to set my default
spacing for dashed line, which I guess might need rcParams.
In [1]: line,=plot(range(10),'--')
In [2]: line.set_dashes((5,2))
In [4]: line._dashSeq
Out[4]: (5, 2)
so the _dashSeq is a private attribute and cannot be accessed by
mat.rcParams
it's not in the rc.Params.keys()
thanks for your answer!

See the API document of plot():
http://matplotlib.sourceforge.net/api/axes_api.html#matplotlib.axes.Axes.plot
You may try different combinations of linestyle and marker to achieve your
desired style.

Yep, that's what I was expecting. It should fail with both show() and
the save as 'png' format. However, it only fails when trying to save
an 'eps'

I think the bigger question is why does it _work_ with show()? I would
expect it to fail. I would rather have it fail everywhere or work
everywhere.
Ben Root

That's not a bug. linewidth is required to be a float, rather than a 
string. Python's typing is generally a little stricter than languages 
such as JavaScript.

Hi, this is not a big deal, but I think that there is a bug while
saving eps figures and passing the linewidth='2.5' as string instead
of float. The following reproduces the error I get here:
plt.plot([1,2,3], 'k', linewidth='2.5')
plt.savefig('teste.png') # Saves OK
# The following fails with linewidth='2.5', but passes with linewidth=2.5
# TypeError: float argument required, not str
plt.savefig('teste.eps')
plt.show() # show is OK for both cases.
matplotlib.__version__
Out[2]: '1.2.x'

Dear all,
I guess Is it not possible to control dash line spacing by set rcParam?
cheers,
Chao
