implementing Python 2.7 and matplotlib when saving figures with custom DPI settings
I've been banging my head against this for hours... I'm experiencing unexpected behavior when trying to save figures using matplotlib in Python 2.7. Specifically, when I set a custom DPI value, the output image appears to be much larger than expected, even when I specify a reasonable figure size. For example, I'm using the following code: ```python import matplotlib.pyplot as plt # Create a simple plot plt.figure(figsize=(5, 5)) plt.plot([1, 2, 3], [4, 5, 6]) plt.title('My Plot') # Save the figure with a custom DPI plt.savefig('my_plot.png', dpi=300) ``` After running this, the produced 'my_plot.png' file is significantly larger than a 5x5 inch figure would normally be at 300 DPI. When I open the image, it appears to be over 1500x1500 pixels, leading me to believe there's an scenario with how the `figsize` and `dpi` parameters are interacting. I've tried adjusting the `figsize` to both smaller and larger values, but the output continues to scale incorrectly. Additionally, I've ensured that my matplotlib version is 1.5.1, which is compatible with Python 2.7. I also checked that other file formats, such as SVG, exhibit the same scaling scenario when saving. Is there a known scenario with matplotlib in Python 2.7 regarding DPI settings? What steps can I take to ensure that the saved image matches the intended size according to the DPI setting? For context: I'm using Python on Linux. Any ideas what could be causing this? My development environment is macOS. What am I doing wrong? This is happening in both development and production on Ubuntu 22.04. Has anyone else encountered this?
