There's a common confusion: np.title doesn't exist in NumPy. You're probably thinking of plt.title from Matplotlib, which is used to add titles to plots. Here's how plt.title works: first import matplotlib and numpy, create some data like a sine wave, plot it, then use plt.title to add a descriptive title above your plot.
The basic syntax for plt.title is simple: just pass the title text as the first argument. You can customize the appearance using parameters like fontsize to control text size, color to change the text color, and fontweight to make it bold or normal. You can even use LaTeX formatting for mathematical expressions in your titles.
Let's see a visual example of how plt.title works. First, we import the necessary libraries. Then we generate data points for a sine wave. We create the plot using plt.plot, add a descriptive title with plt.title, include axis labels for clarity, and finally display the complete plot. The title appears at the top, making the plot self-explanatory.
Matplotlib offers advanced formatting options for titles. You can control the position with the loc parameter, adjust spacing with pad, change font families, apply italic styling, add background boxes with custom colors and borders, and even rotate titles at specific angles. These options give you complete control over your plot's appearance and professional presentation.
