Plotting: series.plot() has different x-limits than plt.plot()

[vfilimonov]

Code Sample, a copy-pastable example if possible

x = [1,2,3]
y = [4,3,5]
plt.plot(x,y,marker='o');  # x-limits are extended
pd.Series(y, index=x).plot(marker='o');  # x-limits are exactly on the first/last points

Problem description

When the data is plotted using Series.plot(), the x-limits are set on the exactly first and last points of the set. This is different from the behavior of matplotlib's plot, where it gives a bit more space.

@vfilimonov This seems to be fixed on the pandas dev version 0.26.0.dev0+557.g0eee324c2

@rohitsanj Great to hear!
Sorry for not checking the dev before reporting.
