To transform a histogram plot in a pandas dataframe into a scatter plot, you can follow these steps:

  1. First, import the necessary libraries:
import pandas as pd
import matplotlib.pyplot as plt
  1. Next, create a pandas dataframe and plot a histogram:
data = pd.DataFrame({'x':[1,3,3,4,5,7,7,8,9,10]})
plt.hist(data['x'], bins=5)
plt.show()

This will create a histogram plot:

Histogram Plot

  1. To transform this histogram plot into a scatter plot, we need to convert the histogram data into a scatter data. This can be done by counting the frequency of each bin and plotting the frequency against the bin values:
counts, bins, _ = plt.hist(data['x'], bins=5)
freq = pd.DataFrame({'x': bins[:-1], 'y': counts})

plt.scatter(freq['x'], freq['y'])
plt.show()

This will create a scatter plot:

Scatter Plot

Note that the scatter plot does not contain any information about the binning of the histogram.
