How to interpolate data from a dataframe and calculate a new one by extracting values at a regular step
0
$begingroup$
My goal would be interpolate values from a data frame and have a new dataframe with an index at a predefined step e new values extracted from the interpolation.
This is what I did but I have only NaN :-(
In [41]:
dfF_4 = pd.read_csv('prova_4.csv').dropna()
dfF_4 = dfF_4.set_index('d 4')
dfF_4.head()
Out[41]:
L 4
d 4
-0.078863 -0.236185
-0.078613 -0.297880
-0.078127 -0.284485
-0.078824 -0.373967
-0.078507 -0.259099
In[42]:
new_index = arange(0, 26.5, 0.05)
dfF_4 = dfF_4.reindex(new_index).interpolate()
dfF_4.head()
Out[42]:
L 4
d 4
0.00 NaN
0.05 NaN
0.10 NaN
0.15 NaN
0.20 NaN
Thanks so much for your help
