If you pass a single column it'll plot it against the index. If you want to plot something quickly, you can use ot function. We are going to use two datasets, just for demonstrating the things we can do with matplotlib and seaborn.ĭf=pd.read_csv("iris.csv") df1=pd.read_csv("India GDP from 1961 to 2017.csv") Basic Usage of pyplot Import pandas as pd import matplotlib.pyplot as plt from matplotlib import style Importing the Data We'll import pandas for reading the data and matplotlib for plotting. Scripting layer can be used using matplotlib.pyplot. We will be looking at the scripting layer since its the most easy to use. Matplotlib has 3 different layers, each layer has different level of customization. Note: Definitions taken straight from Wikipedia. A histogram can be a line histogram or a bar histogram. Histogram - A histogram is an approximate representation of the distribution of numerical or categorical data.The data are displayed as a collection of points, each having the value of one variable determining the position on the horizontal axis and the value of the other variable determining the position on the vertical axis. Scatter Plot - A scatter plot is a type of plot used to visualize relationship between two variables.Outliers may be plotted as individual points. Box plots may also have lines extending from the boxes (whiskers) indicating variability outside the upper and lower quartiles, hence the terms box-and-whisker plot and box-and-whisker diagram. Box Plot - A box plot is a method for graphically depicting groups of numerical data through their quartiles. ![]() In a pie chart, the arc length of each slice (and consequently its central angle and area), is proportional to the quantity it represents. Pie Chart - A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion.Line Plot - A line chart or line plot or line graph or curve chart is a type of chart which displays information as a series of data points called 'markers' connected by straight line segments.It is a basic type of chart common in many fields. ![]() A vertical bar chart is sometimes called a column chart. The bars can be plotted vertically or horizontally. Bar Plot - A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent.We will also be looking at easy ways to make graphs prettier. In this tutorial, we will be using matplotlib and seaborn and looking at common types of plots. Python has a lot of data visualization libraries for common type of visualizations. Data visualization allows us to look at trends and patterns in the data to facilitate decision making. When you have a big amount of air quality data or pollen data it's hard to visualize it or know what to do with it. ![]() In this tutorial, we will be using matplotlib and seaborn. Data Visualization is about taking data and representing it visually to make large data interpretable to humans.
