Some types of graphs that we can make with this package are listed below:
Histogram Pie Plot Box Plot Scatter Plot Line Graph
Installing Matplotlib
• To install it using pip:
python -m pip install -U pip
python -m pip install -U matplotlib
Or
pip install matplotlib
For plotting using Matplotlib, we need to import its Pyplot module as follows:
import matplotlib.pyplot as plt
The pyplot module of matplotlib has built in methods which help in designing a graph with all features. Few of
the functions are explained below:
• The plot(x,y,marker) function is used to create a box-like figure where the actual graph is plotted. To plot x axis
versus y axis, we write plt.plot(x,y). By default, it plots a line graph.
• plt.plot(kind='line')will make a line graph. We can have the following values of the kind parameter to change the
type of the graph needed to make.
Arguments accepted by kind for different plots
kind = Plot type
line Line plot (default)
bar Vertical bar plot
barh Horizontal bar plot
hist Histogram
box Boxplot
area Area plot
pie Pie plot
scatter Scatter plot
List of Pyplot functions to plot different charts and customise plots
• The scatter(x, y) function will plot a scatter graph.
• The show() function will display the figure created.
• The savefig(filename) function can be used to save the figure in your computer.
• The xlabel(Text) function is used to give label to x axis.
