What to Focus On
- Matplotlib is used for 2D plotting in Python.
- Import pyplot as plt using import matplotlib.pyplot as plt.
- A figure is the overall window containing plot components.
- plot() creates a line chart by default.
- The plot() function can take x and y values as parameters.
- Line plots are suitable for continuous data and time-based trends.
- Pandas .plot() is available from version 0.17.0.
- It wraps pyplot plotting functions.
- kind controls the plot type.
Common Mistakes to Avoid
Matplotlib is the same thing as pyplot, and both names mean the full library.
plt.plot() always makes a line chart, so it cannot be used for x and y data points directly.
show() saves the graph as an image, while savefig() only displays it.
Memory Tips
Matplotlib is used for creating static, animated, and interactive 2D plots or figures
Importing pyplot as plt
Figure as the overall window containing plot elements
show() displays the created figure
