Subsequent graphics functions, such as plot, target the active side. Plot data against the left y -axis. x = linspace(0,25); y = sin(x/2); yyaxis left. plot(x,y);plot(x,y) Add another sine wave to the axes using hold on. Keep the current axis limits by setting the limits mode to manual. y2 = 2*sin(x); hold on. axis manual. plot(x,y2) hold off. If you want the axes to choose the appropriate limits, set the limits mode back to automatic.Using the FirstCrossOverValue and SecondCrossoverValue properties of the Axes ' NumericRuler objects ( XAxis, YAxis, ZAxis ), we can position the secondary axis in the desired location. The basic idea is illustrated in the example below. This is for the z-axis, but the same approach can be used for y or x. clear; close all; clc.This is strange. It does in my version of matlab (7.6.0.324 (R2008a)) (you can retrieve version number with the version command). If you want to place the x-axis somewhere in the middle of the picture, this is not possible in my version: the x-axis is either at the top or at the bottom (you can set this with the "XAxisLocation" property). -Commented: Walter Roberson on 6 Jun 2017.

The yyaxis function creates an Axes object with a y-axis on the left and right sides.Axes properties related to the y-axis have two values.However, MATLAB ® gives access only to the value for the active side. For example, if the left side is active, then the YDir property of the Axes object contains the direction for the left y-axis.Axes Appearance. You can customize axes by changing the limits, controlling the locations of the tick marks, formatting the tick labels, or adding grid lines. You also can combine multiple plots, either using separate axes in the same figure, or by combining the plots in the same axes, with the option to add a second y -axis.Call the nexttile function to create the axes objects ax1 and ax2.
