Description

What steps will reproduce the problem?

I was treatting a pressure distribution over airfoil file ("X" x "CP" ) inside a pandas dataframe. When I tried to verify the results. Then I performed a simple plot directelly from the dataframe

the lst_splt list is something like this:

lst_splt = [['0.01','0.03'], ['0.02','0.06'],...]

it was obtained using XFOIL (a pannel method file) ant is on this format:

"""

x Cp

 1.00000    0.24276
 0.99818    0.23883
 0.99591    0.22657
 0.99342    0.21421
 0.99066    0.20128
 0.98759    0.18802

(this file is extense and will not be completely described herein) ... """

reading the file

fl = open(cp_fl,'r') lst = fl.readlines() lst_splt = [ s.replace('#','').split() for s in lst]

creating a dataframe

cp = pd.DataFrame(lst_splt[1:], columns=lst_splt[:1], dtype=float)

checking data

cp.plot()
