Where is matplotlib used?

Matplotlib is a cross-platform, data visualization and graphical plotting library for Python and its numerical extension NumPy. As such, it offers a viable open source alternative to MATLAB. Developers can also use matplotlib's APIs (Application Programming Interfaces) to embed plots in GUI applications.

How do you plot a figure in Python?

Following steps were followed:

1. Define the x-axis and corresponding y-axis values as lists.
2. Plot them on canvas using . plot() function.
3. Give a name to x-axis and y-axis using . xlabel() and . ylabel() functions.
4. Give a title to your plot using . title() function.
5. Finally, to view your plot, we use . show() function.

What is PLT plot Python?

matplotlib.pyplot is a collection of functions that make matplotlib work like MATLAB. Each pyplot function makes some change to a figure: e.g., creates a figure, creates a plotting area in a figure, plots some lines in a plotting area, decorates the plot with labels, etc.

What is Figsize in histogram?

figsize : tuple (width, height) - The size of the output image. layout : tuple (rows, columns) - The layout in which the output graphs must be, for example, (4, 1) gives the figures in a single column and four rows.

What is axes and figure in matplotlib?

A Figure object is the outermost container for a matplotlib graphic, which can contain multiple Axes objects. One source of confusion is the name: an Axes actually translates into what we think of as an individual plot or graph (rather than the plural of “axis,” as we might expect).

The third argument represents the index of the current plot. #the figure has 1 row, 2 columns, and this plot is the first plot.

What are plot axes?

Axes are the lines that are used to measure data on graphs and grids. There are two types of axes: the vertical axis, and the horizontal axis. These are also known as the x and y-axis.
