Dear all,

I have created with fortran the following file:

/
2013:01:02-01,-999.0000, 1.0000000E+00,1.0000000E+00
2013:01:02-02,-999.0000, 2.0000000E+00,0.0000000E+00
2013:01:02-03,-999.0000, 3.0000000E+00,2.0000000E+00
2013:01:02-04,-999.0000, 4.0000000E+00,0.0000000E+00
2013:01:02-05,-999.0000, 5.0000000E+00,3.0000000E+00/
....

I would like to read it and to plot data according to date

so far this is what I do:

/folder = 'meteo_stations'
fname = 'stations_pp.txt'
headers = ['date','dato1','dato2','dato3']
df = pd.read_csv('./'+folder+'/'+fname,)

df.plot(x='date',y='dato2',)/

unfortunately, I get an error?

what shall I do?

Thanks for any kind of helps,

Best regards

Are you using the names parameter in read_csv to set the header names? This works for me

headers = ['date','dato1','dato2','dato3']
df = pd.read_csv('./'+folder+'/'+fname, header=None, names=headers)
df.plot(x='date',y='dato2',)
