0.10.1: DataFrame.plot() does not use integer index as ticks for x axis

[bluefir]

df = DataFrame(index=range(99, -1, -1))
df['y'] = range(100)
df.plot()

I observe a 45-degree line while what I expect to see is the -45-degree line (from top left corner to bottom right corner). Am I doing something wrong?

I'm not on my Mac currently but did you verifiy that df.ix[0] shows 99 connected to y==0 ? I could imagine that the index is self-sorting itself and when you add the Y-column things are all positive direction again? Try do put the data column already in the object constructor.

Yes, I did verify that the data looks as expected.

df.ix[0]

y 99
Name: 0

Needless to say, I started with a more complex thing in my code that worked just fine in 0.9.0 and 0.10.0. You know, I do check before I post. Can you replicate the behavior?

@changhiskhan could you have a look?
