Hi,

I totally new to programming and have been trying to learn python on my own since last month. While plotting the graph it give me error "TypeError: unhashable type: 'numpy.ndarray' and I not at sure why. I checked the web for it, it seems like this error was earlier reported and have been answered, However, it looks the soution is not applicable to me.

Here is the code

import numpy as np from pandas.plotting import register_matplotlib_converters import pandas as pd import matplotlib.pyplot as plt from matplotlib.pylab import rcParams from datetime import datetime

rcParams["figure.figsize"] = 10,6

dataset = pd.read_csv("D:\Data Science\supsales1.csv") print(dataset)

dataset["Month"].astype(object) dataset["Sales"].astype(float)

plt.xlabel("Sales") plt.ylabel("Month") plt.plot(dataset)

Below are the Error Messages

Your question does not appear to have anything to do with pint-pandas. You should probably ask in the pandas or matplotlib issue trackers. They can help you best.
