split title of a figure in matplotlib

Question

I use matplotlib to create a figure with 4 sub-plots in it.

I would like to split one of my title of a subplot, such that each line would be in the centered with res

Answer 1

In addition to the previous answers, if someone wants to automate the operation I have coded a function to make this easy. here is it:

def split_title_line(title_text, split_on='(', max_words=5):  # , max_words=None):
    """
    A function that splits any string based on specific character
    (returning it with the string), with maximum number of words on it
    """
    split_at = title_text.find (split_on)
    ti = title_text
    if split_at > 1:
        ti = ti.split (split_on)
        for i, tx in enumerate (ti[1:]):
            ti[i + 1] = split_on + tx
    if type (ti) == type ('text'):
        ti = [ti]
    for j, td in enumerate (ti):
        if td.find (split_on) > 0:
            pass
        else:
            tw = td.split ()
            t2 = []
            for i in range (0, len (tw), max_words):
                t2.append (' '.join (tw[i:max_words + i]))
            ti[j] = t2
    ti = [item for sublist in ti for item in sublist]
    ret_tex = []
    for j in range (len (ti)):
        for i in range(0, len(ti)-1, 2):
            if len (ti[i].split()) + len (ti[i+1].split ()) <= max_words:
                mrg = " ".join ([ti[i], ti[i+1]])
                ti = [mrg] + ti[2:]
                break

    if len (ti[-2].split ()) + len (ti[-1].split ()) <= max_words:
        mrg = " ".join ([ti[-2], ti[-1]])
        ti = ti[:-2] + [mrg]
    return '\n'.join (ti)

Examples:

In: split_title_line ('Primary school completion (% of girls)')

out:

Primary school completion 
(% of girls)

In: split_title_line ('Primary school completion in the country as % of girls') Out:

Primary school completion in the
country as % of girls

For your question to split titles in matplotlib or so, you can add this ax.set_title(split_title_line(r'Normalized occupied Neighbors', max_words=2))

Hope that everyone benefits from this.
