FAQs

How do you reverse the direction of the axis in MATLAB? ›

How do you flip an image over the Y-axis in MATLAB? ›

You can use the function flip to flip any array along one axis: Aa = flip(A,2); This will work for both a gray-scale and an RGB image. This is equivalent to the following indexing expression for a 3D array (such as an RGB image):

How do you reverse the Y-axis in MATLAB Imshow? ›

By default, the 'imshow' function inverts the y-axis direction when the image is displayed on an axes by setting the 'YDir' property to 'reverse. ' To revert the y-axis direction after calling 'imshow', set the 'YDir' property to 'normal'. Then, to preserve the orientation of the image, flip the image using 'flip'.

How do I rescale the Y-axis in MATLAB? ›

yscale( scale ) sets the scale of the y-axis to be linear or logarithmic in the current axes. Specify scale as "linear" or "log" . You can also omit the parentheses and quotation marks when using this syntax. For example, yscale log is equivalent to yscale("log") .

How do you rotate the Y-axis in MATLAB? ›

ytickangle( ax , angle ) rotates the tick labels for the axes specified by ax instead of the current axes. ang = ytickangle returns the rotation angle for the y-axis tick labels of the current axes as a scalar value in degrees. Positive values indicate counterclockwise rotation.

How do I change the Y-axis to the right in MATLAB? ›

Change Axes Properties

Use yyaxis left to activate the left side and set the direction for the left y-axis. Similarly, use yyaxis right to activate the right side.

How do you flip over the y-axis? ›

We can reflect the graph of any function f about the x-axis by graphing y=-f(x) and we can reflect it about the y-axis by graphing y=f(-x).

How do you mirror across the y-axis? ›

Here is the general rule for reflection across the y-axis: Given an equation y = f ( x ) , the new reflection equation of the reflected graph will be y = f ( − x ) .

How do you control the y-axis in MATLAB? ›

ylim( limits ) sets the y-axis limits for the current axes or chart. Specify limits as a two-element vector of the form [ymin ymax] , where ymax is greater than ymin . ylim( limitmethod ) specifies the limit method MATLAB® uses for automatic limit selection.

How do you flip the Y axis value? ›

How do you change the Y axis units in MATLAB? ›

You can change the x- or y-axis units by right-clicking the mouse on the axis label or by right-clicking on the plot and selecting Analysis Parameters.

What is the Y axis equal in MATLAB? ›

The y-axis is vertical with values increasing from bottom to top. axis equal sets the aspect ratio so that the data units are the same in every direction. The aspect ratio of the x-, y-, and z-axis is adjusted automatically according to the range of data units in the x, y, and z directions.

How do you flip the axis of a matrix in MATLAB? ›

B = flip( A , dim ) reverses the order of the elements in A along dimension dim . For example, if A is a matrix, then flip(A,1) reverses the elements in each column, and flip(A,2) reverses the elements in each row.

How to reverse a graph in MATLAB? ›

H = flipedge( G ) returns a directed graph that has the same edges as G , but with reversed directions. H contains the same node and edge properties as G . H = flipedge( G , s,t ) reverses a subset of edges using the node pairs s and t . H = flipedge( G , idx ) reverses a subset of edges using the edge indices idx .
