matplotlib-users Mailing List for matplotlib

Hi gang,

    I apologize to come up always with noob questions, but it's been a
while I used matplotlib seriously...
Related to the "deleting a line from a plot" subject, I was thinking
about *hiding* the line instead of completely erasing it from the
graph. This is because the user can check or unchech a checkbox that
toggles the line visibility, and it would be much easier to call
set_visible() instead of continuously deleting/replotting the line.
Now, how does this impact on legend? I mean, is there a way with which
I can simply hide a line => update the legend by removing the missing
line label, or show a line => restore the legend label?

Thank you for every pointer.

I've built 0.87.7 from source and the problem disappeared. Thanks.

I had guessed it was the known X11 1.1.2 font problem, too. Oh well...

Some more info might help, such as:
- What python are you using (where did it come from and what version is 
it)?
- What back end are you trying to use?
- Did you create and configure a matplotlibrc file?
Admittedly errors in these errors usually result in a traceback instead 
of a segfault, but it's a start.

Hi,

if I use comments and the last character in the file is not space or \n then 
the last value is not returned by mlab.py's load method, due to a bug in the 
comment stripping (index returns -1 if no comment is found).

If the for loop is changed to the following, it works again:

for i,line in enumerate(fh):
        if i<skiprows: continue
        commentIdx = line.find(comments) #
        if commentIdx!=-1: #
            line = line[:commentIdx].strip() #
        if not len(line): continue
        if usecols is not None:
            vals = line.split(delimiter)
            row = [converters.get(i,float)(vals[i]) for i in usecols]
        else:
            row = [converters.get(j,float)(val) for j,val in 
enumerate(line.split(delimiter))]
        thisLen = len(row)
        X.append(row)

Lines ending with # are changed/added

Have fun,

Hi John,

    sorry to come back so late with this subject. Well, I have tried
your suggestion:

No way, it doesn't update the axes. Uhm, in my plot I have only lines
and one legend, nothing more. Even if I try a simple case with 2 lines
and I remove one of them, the axes still stay with their previous
limits. I must be missing something.

No problem, as soon as I am able to update the axes, I will add that
info to the wiki.

Thank you.

Andrea.
