How to Set the Y-Axis Range of a Subplot to [0,1000]?

Adjusting Subplot Axis Range: A Comprehensive Solution

When working with subplots, controlling the axis range can be crucial to visualize your data effectively. In this case, you are facing an issue with setting the y-axis range of your second subplot to [0,1000].

The provided script attempts to use pylab.ylim([0, 1000]), but this approach does not work. To address this problem, follow the correct procedure:

from matplotlib import pyplot as plt

# Create the subplot
plt.subplot(h, w, 2)

# Plot the FFT data
plt.plot(abs(fft))

# Set the y-axis range
plt.ylim([0, 1000])

# Save the figure
plt.savefig("SIG.png", dpi=200)

# Show the plot
plt.show()

Important Note:

• The ylim() command should be executed after the plot has been created using plot().

Additional Improvements:

In addition to setting the axis range, you can consider the following improvements:

• Replace pylab with matplotlib.pyplot to avoid deprecation issues.
• Use plt.xlim() to adjust the x-axis range if necessary.
• Consider using a logarithmic scale on the y-axis or x-axis to better visualize the data.
• Add proper labeling and gridlines for better readability.
