14 Μαρ 2017 · By definition, the axis number of the dimension is the index of that dimension within the array's shape. It is also the position used to access that dimension during indexing. For example, if a 2D array a has shape (5,6), then you can access a[0,0] up to a[4,5].
20 Οκτ 2017 · import numpy as np a = np.array([[1, 0, 0], [0, 1, 2]], dtype=np.float) >>> a Out[]: array([[ 1., 0., 0.], [ 0., 1., 2.]]) >>> a[0, :] # Slice index 0 of first axis Out[]: array([ 1., 0., 0.]) # Get values along second axis `x` of length 3 >>> a[:, 2] # Slice index 2 of second axis Out[]: array([ 0., 2.])
Explore math with our beautiful, free online graphing calculator. Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more.
The most straight forward way is just to call plot multiple times. Example: >>> plot(x1, y1, 'bo') >>> plot(x2, y2, 'go') Copy to clipboard. If x and/or y are 2D arrays, a separate data set will be drawn for every column. If both x and y are 2D, they must have the same shape.

How to configure axis on pgfplots? Similar for this. \documentclass{article} \usepackage{tikz,pgfplots} \pagestyle{empty} \begin{document} \begin{tikzpicture}[>=latex] %x axis. \draw[->] (-5,0) -- (5,0) node[below] {$x$}; \foreach \x in {-4,...,-1,1,2,...,4} \draw[shift={(\x,0)}] (0pt,2pt) -- (0pt,-2pt) node[below] {\footnotesize $\x$}; %y axis.
A 2D coordinate plane is formed by the intersection of a horizontal number line called the x-axis and a vertical number line called the y-axis. The two axes (plural for axis) intersect at a point called the origin.
