Matplotlib.gridspec.GridSpec Class in Python Last Updated : 12 Jul, 2025 Comments Improve Suggest changes Like Article Like Report See More Matplotlib is an amazing visualization library in Python for 2D plots of arrays. Matplotlib is a multi-platform data visualization library built on NumPy arrays and designed to work with the broader SciPy stack. matplotlib.gridspec.GridSpec The matplotlib.gridspec.GridSpec class is used to specify the geometry of the grid to place a subplot. For this, to work the number of rows and columns must be set. Optionally, tuning of subplot layout parameters can be also done. Syntax: class matplotlib.gridspec.GridSpec(nrows, ncols, figure=None, left=None, bottom=None, right=None, top=None, wspace=None, hspace=None, width_ratios=None, height_ratios=None)Parameters: nrows: It is an integer representing the number of rows in the grid. ncols: It is an integer representing the number of columns in the grid. figure: It is an optional parameter used to draw figures. left, right, top, bottom: These are optional parameters used to define the extent of the subplots as fraction of figure width or height. wspase: It is an optional float argument used to reserve the width space between subplots. hspace: It is an optional float argument used to reserve the height space between subplots. width_ratios: It is an optional parameter that represents the width ratios of the columns. height_ratios: It is an optional parameter that represents the width ratios of the rows. Methods of the class: get_subplot_params(self, figure=None): It returns a dictionary of subplot layout parameters. unless a figure attribute is set, the default parameter is from rcParams. ight_layout(self, figure, renderer=None, pad=1.08, h_pad=None, w_pad=None, rect=None): It is used to give specific padding to adjust the subplots. Here pad is a float value that sets padding between figure edge and the subplot edges as a fraction of the font size. The h_pad and w_pad are optional argument used to set padding between adjacent subplots. Also rect is used to normalize figure coordinates of a rectangle that includes all the subplot area. its default is (0, 0, 1, 1). It is a tuple of 4 floats. Example 1: Python3 import numpy as np import matplotlib.pyplot as plt from matplotlib.gridspec import GridSpec gs = GridSpec(8, 39) ax1 = plt.subplot(gs[:6, :35]) ax2 = plt.subplot(gs[6:, :]) data1 = np.random.rand(6, 35) data2 = np.random.rand(2, 39) ax1.imshow(data1) ax2.imshow(data2) plt.show() Output: Example 2: Python3 import matplotlib.pyplot as plt import matplotlib.gridspec as gridspec fig = plt.figure(figsize =([7, 4])) gs = gridspec.GridSpec(2, 6) gs.update(wspace = 1.5, hspace = 0.3) ax1 = plt.subplot(gs[0, :2]) ax1.set_ylabel('ylabel', labelpad = 0, fontsize = 12) ax2 = plt.subplot(gs[0, 2:4]) ax2.set_ylabel('ylabel', labelpad = 0, fontsize = 12) ax3 = plt.subplot(gs[0, 4:6]) ax3.set_ylabel('ylabel', labelpad = 0, fontsize = 12) ax4 = plt.subplot(gs[1, 1:3]) ax4.set_ylabel('ylabel', labelpad = 0, fontsize = 12) ax5 = plt.subplot(gs[1, 3:5]) ax5.set_ylabel('ylabel', labelpad = 0, fontsize = 12) plt.show() Output: Create Quiz Comment R rajukumar19 Follow 0 Improve R rajukumar19 Follow 0 Improve Article Tags : Python Write From Home Python-Library Python-matplotlib Explore Python FundamentalsPython Introduction 2 min read Input and Output in Python 4 min read Python Variables 4 min read Python Operators 4 min read Python Keywords 2 min read Python Data Types 8 min read Conditional Statements in Python 3 min read Loops in Python - For, While and Nested Loops 5 min read Python Functions 5 min read Recursion in Python 4 min read Python Lambda Functions 5 min read Python Data StructuresPython String 5 min read Python Lists 4 min read Python Tuples 4 min read Python Dictionary 3 min read Python Sets 6 min read Python Arrays 7 min read List Comprehension in Python 4 min read Advanced PythonPython OOP Concepts 11 min read Python Exception Handling 5 min read File Handling in Python 4 min read Python Database Tutorial 4 min read Python MongoDB Tutorial 3 min read Python MySQL 9 min read Python Packages 10 min read Python Modules 3 min read Python DSA Libraries 15 min read List of Python GUI Library and Packages 3 min read Data Science with PythonNumPy Tutorial - Python Library 3 min read Pandas Tutorial 4 min read Matplotlib Tutorial 5 min read Python Seaborn Tutorial 3 min read StatsModel Library - Tutorial 3 min read Learning Model Building in Scikit-learn 6 min read TensorFlow Tutorial 2 min read PyTorch Tutorial 6 min read Web Development with PythonFlask Tutorial 8 min read Django Tutorial | Learn Django Framework 7 min read Django ORM - Inserting, Updating & Deleting Data 4 min read Templating With Jinja2 in Flask 6 min read Django Templates 5 min read Build a REST API using Flask - Python 3 min read Building a Simple API with Django REST Framework 3 min read Python PracticePython Quiz 1 min read Python Coding Practice 1 min read Python Interview Questions and Answers 15+ min read Like
