[Matplotlib-users] minor ticks

[Fabrice S. <si...@lm...>]

Contrary to what the on-line doc says, the set_xticks method of an axes
instance does not have the 'minor' keyword argument...


   S1.set_xticks(Xticksm, minor=True)
TypeError: set_xticks() got an unexpected keyword argument 'minor'


__version__  = '0.90.1'
__revision__ = '$Revision: 3333 $'
__date__     = '$Date: 2007-05-31 09:52:25 -0400 (Thu, 31 May 2007) $'

This works for me -- I wonder if your version is out of date.  0.90.1
is pretty old

In [7]: ax.set_xticks([1.1,1.2,1.3], minor=True)
Out[7]:
[<matplotlib.axis.XTick instance at 0x817418c>,
 <matplotlib.axis.XTick instance at 0x8f318ec>,
 <matplotlib.axis.XTick instance at 0x8f319cc>]

In [8]: draw()

In [9]: matplotlib.__version__
Out[9]: '0.91.2svn'

[Matplotlib-users] minorLocator

[Yves R. <yve...@ep...>]

Hi all,

How is it possible to display by default the minor ticks with an 
interval 5 times
smaller than the major ticks.

I can do that for a known range of data : for example :

ax = pt.gca()
ax.xaxis.set_major_locator(MultipleLocator(10))
ax.xaxis.set_minor_locator(MultipleLocator(10/5.))


but I would like to have the major still set by default, i.e. :
ax.xaxis.set_major_locator(AutoLocator())

and now the minor automatically set to 1/5. of the value used for the major.

How can I do that ?


Thanks for your help,

yves

[Matplotlib-users] LateX Legend

[Yves R. <yve...@ep...>]

Dear List,

How is it possible to write legend text with LateX fonts ?
Even with
rc('text', usetex=True)
the legend created with the command "legend" do not appear with LateX fonts.

I try something like :

pt.legend(('$\rm{total baryons}$'))

but the \rm is badly interpreted :-( .

Thanks for your help.

yves

Does this work better?

pt.legend((r'$\rm{total baryons}$'))

Dear Yves,

Here is the trick :

ax = gca()
ax.xaxis.set_major_locator(AutoLocator())
x_major = ax.xaxis.get_majorticklocs()
dx_minor =  (x_major[-1]-x_major[0])/(len(x_major)-1) /5.
ax.xaxis.set_minor_locator(MultipleLocator(dx_minor))

Cheers !

yves
