Matplotlib: Unexpected Behavior When Using Subplot with Gridspec for Complex Layouts

matplotlib gridspec subplots Python

Does anyone know how to I'm not sure how to approach I tried several approaches but none seem to work. I'm trying to create a complex figure layout using Matplotlib's `gridspec` feature, but I'm encountering unexpected behavior when I try to adjust the spacing between subplots. I want to create a 2x2 grid, where the top row contains two plots and the bottom row contains a single plot that spans both columns. However, when I try to set the `wspace` and `hspace` parameters, it doesn't seem to reflect my changes in the output. Here's what my code looks like: ```python import matplotlib.pyplot as plt import matplotlib.gridspec as gridspec # Create a 2x2 gridspec layout fig = plt.figure(figsize=(10, 6)) gs = gridspec.GridSpec(2, 2, width_ratios=[1, 1], height_ratios=[1, 2]) # Add subplots to the gridspec ax1 = fig.add_subplot(gs[0, 0]) ax2 = fig.add_subplot(gs[0, 1]) ax3 = fig.add_subplot(gs[1, :]) # This spans both columns # Sample data ax1.plot([1, 2, 3], [1, 4, 2]) ax2.plot([1, 2, 3], [2, 3, 5]) ax3.plot([1, 2, 3], [2, 5, 1]) # Attempt to set spacing plt.subplots_adjust(wspace=0.5, hspace=0.5) plt.show() ``` When I run this code, the spacing between the plots seems unchanged, and the subplots appear too close together. I expected the `wspace` and `hspace` adjustments to create more space between the plots, but they don't seem to take effect. I’ve tried tweaking the spacing values, but the output remains the same. I'm using Matplotlib version 3.4.3. Is there something I'm overlooking or a better approach to achieve the desired layout? Any insights would be greatly appreciated! Thanks in advance! I'm using Python latest in this project. Any suggestions would be helpful. I recently upgraded to Python 3.9.
