Axes in MATLAB®
How to adjust axes properties in MATLAB®, axes titles, styling and coloring axes and grid lines, ticks, tick labels and more.
Position Multiple Axes in Figure
Position two Axes objects in a figure and add a plot to each one.
Specify the position of the first Axes object so that it has a lower left corner at the point (0.1 0.1) with a width and height of 0.7. Specify the position of the second Axes object so that it has a lower left corner at the point (0.65 0.65) with a width and height of 0.28. By default, the values are normalized to the figure. Return the Axes objects as ax1 and ax2.
figure
ax1 = axes('Position',[0.1 0.1 0.7 0.7]);
ax2 = axes('Position',[0.65 0.65 0.28 0.28]);
Add a plot to each Axes object. Specify the axes by passing it as the first input argument to the graphics function. Most graphics functions reset some axes properties, such as the tick values and labels. However, they do not reset the axes position.
figure
ax1 = axes('Position',[0.1 0.1 0.7 0.7]);
ax2 = axes('Position',[0.65 0.65 0.28 0.28]);
contour(ax1,peaks(20))
surf(ax2,peaks(20))
fig2plotly(gcf);
Unrecognized field name "Fill". We had trouble parsing the contour object. This trace might not render properly.
Make Axes the Current Axes
Create two overlayed Axes objects. Then, specify the current axes and add a plot.
First create two Axes objects and specify the positions. Display the box outline around each axes. Return the Axes objects as ax1 and ax2.
figure
ax1 = axes('Position',[0.1 0.1 .6 .6],'Box','on');
ax2 = axes('Position',[.35 .35 .6 .6],'Box','on');
Make ax1 the current axes. This action brings the axes to the front of the display and makes it the target for subsequent graphics functions. Add a line plot to the axes.
figure
ax1 = axes('Position',[0.1 0.1 .6 .6],'Box','on');
ax2 = axes('Position',[.35 .35 .6 .6],'Box','on');
axes(ax1)
x = linspace(0,10);
y = sin(x);
