hi all,
when i make any numeric scatter plot containing floats, the formatted tick labels always have leading zeros, e.g “0.5” as opposed to “.5” in the labels.
for example:
x = rand(10)
scatter(x,x)
is there any way to change this to remove the leading zeros? i have tried:
s = subplot(111)
majorFormatter = FormatStrFormatter(’%0.1f’)
s.xaxis.set_major_formatter(majorFormatter)
scatter(x,x)
but it does not work. i also tried “%.f” but it does not work either. the matlab default is to plot without the leading zero and i am trying to recreate this.
thank you.
FormatStrFormatter (and other formatters) rely on Python's string
interpolation, and It does not seem to be possible to get rid of the
leading zero (Built-in Types — Python 3.12.0 documentation).
I think what you can do is to replace "0." with "." after the
interpolation. Something like below works for me.
from matplotlib.ticker import ScalarFormatter
s = subplot(111)
class ScalarFormatterNoLeadingZero(ScalarFormatter):
def pprint_val(self, x):
s = ScalarFormatter.pprint_val(self, x)
return s.replace("0.",".")
s.xaxis.set_major_formatter(ScalarFormatterNoLeadingZero())
HTH,
