Change main plot legend label text

Question

So far I have been able to label the subplots just fine but I\'m having an issue with the main one.

Here\'s the relevant part of my code:

data_BS_P =

The answer by ksindi works for setting the labels, but as some others commented, it can break the legend colours when used with seaborn (in my case a scatterplot: the dots and text didn't line up properly anymore). To solve this, also pass the handles to ax.legend.

# the legend has often numbers like '0.450000007', the following snippet turns those in '0.45'
label_list = []
for t in ax.get_legend_handles_labels():
    # the first result will be all handles, i.e. the dots in the legend
    # the second result will be all legend text
    label_list.append(t)

new_list = []
for txt in label_list[1]:
    if txt[0] == '0':
        txt = str(txt)[:4]
    new_list.append(txt)
label_list[1] = new_list

ax.legend(handles=label_list[0], labels=label_list[1])
