How matplotlib shares axes
This article mainly explains "how matplotlib shares axes". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's ideas to study and learn how to share axes with matplotlib.
Preface
1. Overview
Shared axes are the x or y axes shared between several sub-images. This section focuses on how to share axes when mapping with matplotlib.
Pyplot.subplots (nrows = 1Magna Ncols = 1Magna sharex = False,sharey = False,squeeze = True,subplot_kw = none, gridspec_kw = none, * * fig_kw)
Parameters:
Nrows: number of Lin
Ncols: number of columns
Sharex: whether to share X-axis coordinates
Sharey: whether to share Y-axis coordinates
Return value: array of Figure,Axes objects
1. Sharex and sharey code example:''1. Program purpose: based on sharex and sharey to achieve (1) share x axis (2) share y axis (3) share x axis and y axis (4) adjust the distance between subgraphs 2.
