Colormaps in Plots: Program 1

Lineplot with Colormap

import matplotlib.pyplot as plt import numpy as np import matplotlib.cm as cm x = np.linspace(0, 10, 100) y = np.sin(x) colors = cm.viridis(np.linspace(0, 1, 10)) # Using the 'viridis' colormap plt.figure(figsize=(8, 6)) for i, color in enumerate(colors): plt.plot(x, y + i*0.1, color=color, label=f'Line {i+1}') plt.title('Line Plot with Colormap') plt.xlabel('x') plt.ylabel('y') plt.legend() plt.grid(True) plt.savefig('colormap_1.png') plt.show() Run Code

Output 1

Colormaps in Plots: Program 2

Scatter Plot with Colormap

import matplotlib.pyplot as plt import numpy as np import matplotlib.cm as cm x = np.random.rand(100) y = np.random.rand(100) colors = np.sqrt(x**2 + y**2) # Color by the distance from origin plt.figure(figsize=(8, 6)) scatter = plt.scatter(x, y, c=colors, cmap='plasma', edgecolor='k') plt.colorbar(scatter, label='Color intensity') plt.title('Scatter Plot with Colormap') plt.xlabel('x') plt.ylabel('y') plt.grid(True) plt.savefig('colormap_2.png') plt.show() Run Code
