Question

I have a data set of data with 7 different variables. how do you make the histogram of a variable?

Answer 1

I really recommend matplotlib module for that. However, if you don't have one:

(below find a code I made once for a similar inquiry ;)

Answer 2

Try this:

import matplotlib.pyplit as plt
import pandas as pd

data = pd.read_csv(your_filename_here, dtype=your_datatypes_here)
# here you have read the data as proper datatypes, so that the data is of any numeric format

# draw the histogram
plt.figure(figsize=(10, 8))
plt.hist(data)
plt.show()

If you have any problems, please save your code here and publish it, so we can see and may help you.

Answer 3

Oh, I see it's a Python2 syntax, not Python3. Make sure your implementation is a proper one.

When using read_csv, add a parameter dtype={'profit': np.float32, 'invest': np.float32}
Perhaps it is read as strings and that's why histplot doesn't work.

Also, for a dataset summary, you might want to try the .describe() method. It's very informative and it's just one line to add :)

print(df.describe())
