[Solved] Remove nan from annotations [closed]

by


@user1672063: The following solve your problem:

# let name your initial record "record"
# record = [{'yanchor': 'bottom', 'xanchor': 'auto', 'x': u'2018-Q3', 'y': 169.80000000000001, 'text': '169.8', 'showarrow': False},..]
#
# Let initialise a new record
newrecord = []
for d in record:
    if d['y'] is nan:   # provided that you "import numpy.nan as nan" at the beginning
       del d['y']
    newrecord.append(d)

# The “newrecord” corresponds the new record without d[y] = nan.
