From the MATLAB help: By default, imagesc plots the y-axis from lowest to highest value, top to bottom. To reverse this, type set(gca,'YDir','normal'). This will reverse both the y-axis and the image. You can also use axis xy which does something similar (the default is axis ij which puts the lowest index on top). i tried axis xy but it ...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. axis image is the same as axis equal except that the plot box fits tightly around the data. axis square makes the current Axes region square (or cubed when three-dimensional).

Description. B = flip(A) returns array B the same size as A , but with the order of the elements reversed. The dimension that is reordered in B depends on the shape of A: If A is vector, then flip(A) reverses the order of the elements along the length of the vector. If A is a matrix, then flip(A) reverses the elements in each column.Alternatively, we could use the following code to reverse the x-axis: #define x and y. x = [1, 4, 8, 11, 13, 14] #create scatterplot of x and y. plt.scatter(x, y) #reverse x-axis. Notice that the x-axis now ranges from 14 to 0 instead of 0 to 14. Lastly, we could use the following code to reverse both axes:Inverse Y axis with negative values.

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.

Here's an example of how the plot titles currently look:Modify Properties of Charts with Two y-Axes. 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.

The default behavior of imshow is to put the origin of the coordinate system in the upper left corner. This is different from plotting scientific data, such as two entities x and y against each other, where the origin, i.e. the point corresponding to the coordinate (0,0), is in the lower left corner, with the (positive) x-axis extending to the right and the (positive) …

You can change the direction of increasing values along the y-axis by setting the YDir property of the Axes object. If you want the values to increase from bottom to top (2-D view), then set the value to 'normal'. Alternatively, if you want the values to decrease from bottom to top, then set the value to 'reverse'.yticks and yticklabels were introduced in MATLAB 2016b. For earlier versions, to add additional y-ticks alongwith the current y-ticks, and change y-tick labels like those in the question, you can use this: set(gca, 'YTick', unique([-60, 60, get(gca, 'YTick')])); %-60 and 60 are the additional ticks that'll be added to y axis.2 Answers.
