Pyplot is a state-based interface to a Matplotlib module which provides a MATLAB-like interface. Sample Code - Python3 1== # sample code import matplotlib.pyplot as plt plt.plot([1, 2, 3, 4], [16, 4, 1, 8]) plt.show() Output: matplotlib.pyplot.show() Function The show() function in pyplot module of matplotlib library is used to display all figures. Syntax: matplotlib.pyplot.show(*args, **kw) Parameters: This method accepts only one parameter which is discussed below: block : This parameter is used to override the blocking behavior described above. Returns: This method does not return any value. Below examples illustrate the matplotlib.pyplot.show() function in matplotlib.pyplot: Example #1: Python3 1== # Implementation of matplotlib function import matplotlib.pyplot as plt import numpy as np fig = plt.figure() x = np.arange(20) / 50 y = (x + 0.1)*2 val1 = [True, False] * 10 val2 = [False, True] * 10 plt.errorbar(x, y, xerr = 0.1, xlolims = True, label ='Line 1') y = (x + 0.3)*3 plt.errorbar(x + 0.6, y, xerr = 0.1, xuplims = val1, xlolims = val2, label ='Line 2') y = (x + 0.6)*4 plt.errorbar(x + 1.2, y, xerr = 0.1, xuplims = True, label ='Line 3') plt.legend() fig.suptitle('matplotlib.pyplot.show() Example') plt.show() Output: Example #2: Python3 1== # Implementation of matplotlib function import numpy as np import matplotlib.pyplot as plt x = np.linspace(0, 10, 500) y = np.sin(x**2)+np.cos(x) fig, ax = plt.subplots() ax.plot(x, y, label ='Line 1') ax.plot(x, y - 0.6, label ='Line 2') ax.legend() fig.suptitle('matplotlib.pyplot.show() Example') plt.show() Output: Comment More infoAdvertise with us Next Article Interview Preparation For Software Developers S shubhamsingh10 Follow Improve Article Tags : Python Python-matplotlib Practice Tags : python Similar Reads Interview PreparationInterview Preparation For Software DevelopersMust Coding Questions - Company-wise Must Do Coding Questions - Topic-wiseCompany-wise Practice ProblemsCompany PreparationCompetitive ProgrammingSoftware Design-PatternsCompany-wise Interview ExperienceExperienced - Interview ExperiencesInternship - Interview ExperiencesPractice @GeeksforgeeksProblem of the DayTopic-wise PracticeDifficulty Level - SchoolDifficulty Level - BasicDifficulty Level - EasyDifficulty Level - MediumDifficulty Level - HardLeaderboard !!Explore More...Data StructuresArraysLinked ListStackQueueBinary TreeBinary Search TreeHeapHashingGraphAdvance Data StructuresMatrixStringAll Data StructuresAlgorithmsAnalysis of AlgorithmsSearching AlgorithmsSorting AlgorithmsPattern SearchingGeometric AlgorithmsMathematical AlgorithmsRandomized AlgorithmsGreedy AlgorithmsDynamic ProgrammingDivide & ConquerBacktrackingBranch & BoundAll AlgorithmsProgramming LanguagesCC++JavaPythonC#Go LangSQLPHPScalaPerlKotlinWeb TechnologiesHTMLCSSJavaScriptBootstrapTailwind CSSAngularJSReactJSjQueryNodeJSPHPWeb DesignWeb BrowserFile FormatsComputer Science SubjectsOperating SystemsDBMSComputer NetworkComputer Organization & ArchitectureTOCCompiler DesignDigital Elec. & Logic DesignSoftware EngineeringEngineering MathematicsData Science & MLComplete Data Science CourseData Science TutorialMachine Learning TutorialDeep Learning TutorialNLP TutorialMachine Learning ProjectsData Analysis TutorialTutorial LibraryPython TutorialDjango TutorialPandas TutorialKivy TutorialTkinter TutorialOpenCV TutorialSelenium TutorialGATE CSGATE CS NotesGate CornerPrevious Year GATE PapersLast Minute Notes (LMNs)Important Topic For GATE CSGATE CoursePrevious Year Paper: CS exams Like
