From csv, How can I plot 2 variables (P vs V) in a plot with 3rd variable (tot_r) determining the shade of the coordinate? (In python)

Question

As in csv file below, How can I plot 2 variables (P vs V) in a plot with 3rd variable (tot_r) determining the shade of the coordinate? (In python). Total dataset is of 100,000 rows.

csv file- P,V,tot_r

Thanks!!

Answer 1

From the data, looks like p, V, tot_r are all continuous. So, code below will pull the data from file data.csv and build a scatter plot as shown in attached graph

import openpyxl
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns

#df = pd.read_csv("data.csv")
cmap = sns.cubehelix_palette(as_cmap=True)
f, ax = plt.subplots(figsize=(20, 5))
points = ax.scatter(df.p, df.V, c=df.tot_r, s=30, cmap=cmap)
f.colorbar(points)

Graphs output
