Here are the steps to plot a scatter diagram using Pandas. The pandas documentation describes qcut as a “Quantile-based discretization function.” This basically means that qcut tries to divide up the underlying data into equal sized bins. Combining the results. Title to use for the plot. import matplotlib.pyplot as plt import pandas as pd from sklearn.metrics import r2_score dataset = pd.read_csv ("datasets.csv") print (dataset) qc = pd.qcut (dataset ['Active'], q=8, precision=0) qc_val = qc.value_counts ().sort_index () print (qc_val) The bining ranges output is- The Binning of data is very helpful to address those. Scatter plot are useful to analyze the data typically along two axis for a set of data. Sort column names to determine plot ordering. Lots of buzzwords floating around here: figures, axes, subplots, and probably a couple hundred more. Matplotlib Scatter Plot Color by Category in Python. See matplotlib documentation online for more on this subject, If kind = ‘bar’ or ‘barh’, you can specify relative alignments Use pandas.qcut() function, the Score column is passed, on which the quantile discretization is calculated.
