point plot in python code example
Example 1: python add a point to a plot
# Basic syntax
plt.plot(x, y, 'marker')
# Example usage:
import matplotlib.pyplot as plt
import numpy as np
# Data to plot
x = np.linspace(0, 10, 100)
# Plot figure
fig = plt.figure()
plt.plot(x, np.sin(x), '-')
# Add point
plt.plot(5, 0, 'ro')
# Note, see all marker styles here:
# https://matplotlib.org/stable/api/markers_api.html
Example 2: how to plot a scatter plot in matplotlib
# Import matplotlib
import matplotlib.pyplot as plt
# Set plot space as inline for inline plots and qt for external plots
%matplotlib inline
# Set the figure size in inches
plt.figure(figsize=(10,6))
plt.scatter(x, y, label = "label_name" )
# Set x and y axes labels
plt.xlabel('X Values')
plt.ylabel('Y Values')
plt.title('Scatter Title')
plt.legend()
plt.show()
Example 3: scatter plot python
df.plot('x_axis', 'y_axis', kind='scatter')
