![]() # Mark each data value and customize the linestyle: In this example, each data value is labeled with the letter “o”, and given a dashed linestyle “–” : import matplotlib.pyplot as plt ![]() linestyle is an argument used to customize the appearance of lines between data values, or else remove them altogether.marker is an argument used to label each data value in a plot with a ‘ marker ‘.Marker and linestyle are matplotlib keywords that can be used to customize the appearance of data in a plot without modifying data values. A simple plot created with the plot() function: How to Customize Plot Appearance with Marker & Linestyle Parameter for an array of Y axis coordinates.Ī line ranging from x=2, y=4 through x=8, y=9 is plotted by creating 2 arrays of (2,8) and (4,9) : import matplotlib.pyplot as pltįigure 1.Parameter for an array of X axis coordinates.In this case, plot() takes 2 parameters for specifying plot coordinates: The simplest example uses the plot() function to plot values as x,y coordinates in a data plot. The () function provides a unified interface for creating different types of plots. How to Create a Simple Plot with the Plot() Function ![]() Matplotlib’s series of pyplot functions are used to visualize and decorate a plot. For information about pyplot functions and terminology, refer to: What is Pyplot in Matplotlib Display a plot in Python: Pyplot Examples The pyplot interface is easier to implement than the OO version and is more commonly used. The OO API provides direct access to matplotlib’s backend layer.
