Create a scatter plot of the fifth column in hwydata against the left y -axis. Add a title and axis labels. load( 'accidents.mat', 'hwydata' ) ind = 1:51;I would like to make a heatmap from tabular data. My code is below. The heatmap has y-axis values descending order, I would like to them in ascending order. However using set(gca..) gives me the following error:The name 'YDir' is not an accessible property for an instance of class 'matlab.graphics.chart.HeatmapChart'. In the default 2-D view, the x-axis values increase from left to right and the y-axis values increase from bottom to top. The z-axis points out of the screen. You can change the direction of increasing values by setting the associated property to reverse. For example, setting XDir to reverse, set(gca,'XDir','reverse')

To reverse the order of its columns, I type the fliplr (M) command. M2=fliplr (M) M2 will be a new matrix obtained by flipping M1 horizontally about the y-axis, with the columns reversed." M 2 = (2 1 4 3) M 2 = ( 2 1 4 3) To reverse the order of rows in a matrix M, I can use the built-in flipud (M) function, which flips the matrix vertically.

When creating a second y axis, the title is oriented in the same direction as the first axis. I would prefer to reverse the text of the second y axis so that you would need to tilt your head to the right to read.

semilogy(X,Y) plots x - and y -coordinates using a linear scale on the x -axis and a base-10 logarithmic scale on the y -axis. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix.

Description. example. B = fliplr(A) returns A with its columns flipped in the left-right direction (that is, about a vertical axis). If A is a row vector, then fliplr(A) returns a vector of the same length with the order of its elements reversed. If A is a column vector, then fliplr(A) simply returns A. For multidimensional arrays, fliplr ...In this code, we plot the video and eye position separately to adjust the y-axis limits of both plots to match the reversed y-axis of the eye position data.

Hello Giorgia, 'fplot' is mostly used to plot a curve defined by y=f (x) where 'x' is input and 'y' is output which is the standard convention. I would recommend you use a simple 'plot' function since you will get control over how you want to represent the data in the plot. Refer to the following documentation for more details:

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.
