Python Line Plot Styles in Matplotlib
Below are the examples by which we line plot styles in Matplotlib in Python:
Example 1: Plotting a Simple Line Plot Styles in Matplotlib
In this example, we use Matplotlib to visualize the marks of 20 students in a class. Each student’s name is paired with a randomly generated mark, and a dashed magenta line graph represents the distribution of these marks.
Python3
import matplotlib.pyplot as pltimport random as randomstudents = ["Jane","Joe","Beck","Tom", "Sam","Eva","Samuel","Jack", "Dana","Ester","Carla","Steve", "Fallon","Liam","Culhane","Candance", "Ana","Mari","Steffi","Adam"]marks=[]for i in range(0,len(students)): marks.append(random.randint(0, 101))plt.xlabel("Students")plt.ylabel("Marks")plt.title("CLASS RECORDS")plt.plot(students,marks,'m--') |
Output:
Example 2: Adding Markers to Line Plots
In this example, we visualize the marks of 20 students using a line plot. Each student’s name is plotted against their corresponding mark. The line is solid green, and data points are marked with red circles. By this example, we can understand how to change the line styles and markers in Matplotlib.
Python3
import matplotlib.pyplot as pltimport random as randomstudents = ["Jane","Joe","Beck","Tom","Sam", "Eva","Samuel","Jack","Dana","Ester", "Carla","Steve","Fallon","Liam","Culhane", "Candance","Ana","Mari","Steffi","Adam"]marks=[]for i in range(0,len(students)): marks.append(random.randint(0, 101))plt.xlabel("Students")plt.ylabel("Marks")plt.title("CLASS RECORDS")plt.plot(students, marks, color = 'green', linestyle = 'solid', marker = 'o', markerfacecolor = 'red', markersize = 12) |
Output:
Example 3: Adding Grid Lines in Line Plots
In this example, we use Matplotlib to visualize the marks of 20 students in a class. The marks are displayed using a dashed magenta line graph. Grid lines are added to provide better readability and reference across the plot.
Python3
import matplotlib.pyplot as pltimport random as randomstudents = ["Jane", "Joe", "Beck", "Tom", "Sam", "Eva", "Samuel", "Jack", "Dana", "Ester", "Carla", "Steve", "Fallon", "Liam", "Culhane", "Candance", "Ana", "Mari", "Steffi", "Adam"]marks = []for i in range(0, len(students)): marks.append(random.randint(0, 101))plt.xlabel("Students")plt.ylabel("Marks")plt.title("CLASS RECORDS")plt.plot(students, marks, 'm--')# Adding grid linesplt.grid(True, which='both', linestyle='--', linewidth=0.5)plt.show() |

Line plot styles in Matplotlib
Python is a high-level, interpreted, and dynamically typed programming language that can be used to manage huge datasets. Python supports a wide variety of data visualization libraries like Matplotlib, Seaborn, Bokeh, Geoplotlib, Ggplot, and Plotly. Among all these libraries, Matplotlib is comparatively simple and easy to implement.
The Matplotlib library of Python is a popular choice for data visualization due to its wide variety of chart types and its properties that can be manipulated to create chart styles. The matplotlib.pyplot.plot(*args, **kwargs) method of matplotlib.pyplot is used to plot the graph and specify the graph style like color or line style.
