Matlab flip x axis.
Description. B = flipud(A) returns A with its rows flipped in the up-down direction (that is, about a horizontal axis). If A is a column vector, then flipud(A) returns a vector of the same length with the order of its elements reversed. If A is a row vector, then flipud(A) simply returns A. For multidimensional arrays, flipud operates on the ...
If using matplotlib you can try: matplotlib.pyplot.xlim(l, r) matplotlib.pyplot.ylim(b, t) These two lines set the limits of the x and y axes respectively. For the x axis, the first argument l sets the left most value, and the second argument r sets the right most value. Here is my code: figure (666) % setup bottom axis. ax = axes (); hold (ax); ax.XAxis.Scale = 'log'; xlabel (ax, 'Frequency', 'Interpreter', 'latex', 'FontSize', 14); ylabel (ax, 'Power', 'Interpreter', 'latex', 'FontSize', 14); ax_top = axes (); hold (ax_top); ax_top.XAxisLocation = 'top'; ax_top.YAxisLocation = "right"; ax_top.YTick = [];Aug 1, 2020 · which produces the follwing image: Now I want to flip the y-axis so that 50 is at the bottom and 250 is at the top.

This change can be …17. To reverse an axis, you can set the 'XDir' or 'YDir' property of the current axes to 'reverse': set(gca,'XDir','reverse'); %# This flips the x axis. Keep in mind that flipping an axis in this way flips everything in the plot as well. This probably isn't what you want to do for the y axis. You probably just want to flip the y axis labels ...
As be found in the axes documentation, it's simply: set(gca,'XDir','reverse') If you just want the labels flipped, just flip the labels: plot(1:10,1:10) set(gca, 'XTickLabel', flipud( get(gca, 'XTickLabel') )) or for Matlab R2014b or higher a little simpler: a = gca; a.XTickLabel = flipud(a.XTickLabel);In Matplotlib we can reverse axes of a graph using multiple methods. Most common method is by using invert_xaxis () and invert_yaxis () for the axes objects. Other than that we can also use xlim () and ylim (), and axis () methods for the pyplot object. Method 1: Using invert_xaxis () and invert_yaxis () method.The natural logarithm function in MATLAB is log(). To calculate the natural logarithm of a scalar, vector or array, A, enter log(A).

First, load in the image, the generate (x,y) pairs for each intensity in the image. This is done with meshgrid. Once you do this, use scatter to plot each point assuming z = 0 and make the colour of each point the actual intensity seen at the image coordinate. However, you will only see this in a 2D perspective as scatter is naturally 2D.
More Answers (1) to flip the signal about the x-axis (negatives to positives and vice versa), simply use the function gnegate (x). Where X is the signal you're flipping.
