[Matplotlib-users] custom x axis integers boxplot

[pb89]

hi guys,

i guess thats an easy one for you:

fig=plt.figure()
rect=fig.patch
rect.set_facecolor('white')
ax1=fig.add_subplot(111)
bp=boxplot(array)

xlabel('case ID')
ylabel('registration time, sec')
show()

whereas array is a list of lists with 25 entries.

i want to have the axis not from 0 to 25 but from 11 to 36. How can i do
that?

thanks
peter

Try adding these lines before your call to plt.show():

locs, labels = plt.xticks()
plt.xticks(locs, np.arange(11, 36))

Probably a better way would be to the the "pos" arguments to boxplot
(bp=boxplot(array,
pos=range(11, 36)). That *should* work. Let me know if it doesn't.

it tried this before, but it throws an exception:

TypeError: boxplot() got an unexpected keyword argument 'pos'

Oh sorry that should be "... positions=np.arange(11, 36))
