It has most of the graphical elements which compose the plot, like axis lines, grid, and ticks. Most of the plotting in Matplotlib happens in the Axes artist. Composite artists - A collection of artists( Axis, Tick, Axes, Figure etc.).Primitive artists ( Text, Circle, Rectangle etc.).This may include the titles, lines, images, labels, etc. Event which represents the underlying UI events, e.g., picking a data point or manipulating some aspect of the figure.Įverything that you see on a Matplotlib Figure is an artist instance.Renderer which provides the drawing interface for putting ink onto the canvas.FigureCanvas that encapsulates the concept of a surface to draw onto, e.g., a paper.This layer implements the abstract interface classes, which are: The layers from bottom to top are: 0.ěackend layer To accomplish this, Matplotlib has a three-layer stack where a layer that sits on another can communicate with the layer below it, but the layer below has no information about the one above. This enables us to build features and logic into the Figure while keeping the backend relatively simple. Matplotlib provides a way of representing and manipulating the Figure which is separate from rendering this Figure to a user-interface window. Matplotlib has a top-level object called Figure that has and manages all elements in a plot. Most Python sequences are converted to NumPy arrays in the backend, which makes sense for numerical processing. We will work with NumPy because, in Matplotlib, we are constrained to working with lists. Getting started with MatplotlibĪfter installation of the package, import it into your project to start using it: import matplotlib.pyplot as pltĪlso, import the NumPy package: import numpy as np On Anaconda Prompt run: conda install matplotlibįollow this Python for data science tutorial to see how to install packages in different environments. If you have Python and pip installed, run pip install matplotlib from your terminal or cmd: pip install matplotlib Matplotlib is an open-source Python library for making 2D visualizations from NumPy arrays and Pandas DataFrames. We will explore the Matplotlib data visualization package in this article. This is where data visualization comes in.ĭata visualization makes complex data understandable using standard visual graphics like charts, plots, etc. This can be too much data that it is impossible to effectively understand and evaluate it to address business decisions for effective outcomes. Organizations collect and analyze vast amounts of data from sales revenue, marketing performance, customer interactions, inventory levels, production metrics, staffing levels, costs, etc. "A good sketch is better than a long speech"(Napoleon Bonaparte).
