Thank you in advance for your help!

Data for minot_air

Data for minot_soil

I am trying to graph two datasets to one plot and I want it to look somewhat like the first image. The problem is that I keep getting these errors when I run my code (provided below):

FileNotFoundError: [Errno 2] File C:\\Users\\Xavier\\Desktop\\minotDailyAirTemp.csv does not exist: 'C:\\Users\\Xavier\\Desktop\\minotDailyAirTemp.csv'

Why might I be getting these errors? I have checked and that is indeed the location of each of the files. Images two and three show them on my desktop as well as show the file hierarchy:

import pandas as pd
import numpy as np


# data import
minot_air_temp = pd.read_csv(r"C:\Users\Xavier\Desktop\minotDailyAirTemp.csv")
minot_soil_temp = pd.read_csv(r"C:\Users\Xavier\Desktop\Minot_20CM_Daily.csv")

air_temp = pd.read_csv(minot_air_temp, header = 0, index_col = 0,
                         parse_dates=True, infer_datetime_format=True)
soil_temp = pd.read_csv(minot_soil_temp, header = 0, index_col = 0,
                       parse_dates=True, infer_datetime_format=True)

# plot both overlayed
ax = air_temp.plot(figsize=(20,10))
soil_temp.plot(ax=ax)

Error 1:

Answer 1

In the images you included it appears that the files are directly in the Desktop directory and not in a Graphs folder.

Should the file path be “C:\\Users\\Xavier\\Desktop”?
