How to use a (random) *.otf or *.ttf font in matplotlib?

You can use a custom OpenType Font (OTF) or TrueType Font (TTF) in Matplotlib to style your text and labels. Here's how you can do it:

  1. Install the Font: First, make sure you have the font file (.otf or .ttf) installed on your system. If not, you can download and install the font you want to use.

  2. Import Matplotlib:

    import matplotlib.pyplot as plt

  3. Specify the Font:

    You can specify the custom font you want to use with the matplotlib.font_manager.FontProperties class. Provide the path to the font file as the fname argument.

    from matplotlib.font_manager import FontProperties custom_font = FontProperties(fname="/path/to/your/font.otf")

  4. Use the Custom Font:

    Apply the custom font to your text elements like titles, labels, or annotations by setting the fontproperties argument to your FontProperties object.

    plt.title("Title with Custom Font", fontproperties=custom_font) plt.xlabel("X Label", fontproperties=custom_font) plt.ylabel("Y Label", fontproperties=custom_font) plt.annotate("Custom Font", (0.5, 0.5), fontproperties=custom_font)

  5. Create a Plot:

    Build your Matplotlib plot as usual.

    x = [1, 2, 3, 4, 5] y = [10, 20, 15, 30, 25] plt.plot(x, y)

  6. Display the Plot:

    Finally, display your plot using plt.show().

    plt.show()

Here's the complete example:

import matplotlib.pyplot as plt from matplotlib.font_manager import FontProperties # Specify the custom font custom_font = FontProperties(fname="/path/to/your/font.otf") # Create a plot with custom font x = [1, 2, 3, 4, 5] y = [10, 20, 15, 30, 25] plt.plot(x, y) plt.title("Title with Custom Font", fontproperties=custom_font) plt.xlabel("X Label", fontproperties=custom_font) plt.ylabel("Y Label", fontproperties=custom_font) plt.annotate("Custom Font", (0.5, 0.5), fontproperties=custom_font) # Display the plot plt.show()

Replace "/path/to/your/font.otf" with the actual path to your font file. This code will apply the custom font to the title, labels, and annotation in your Matplotlib plot.
