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 ...ylabel('Relative Microgravity Quality') hold on. grid on. Example of what I want: ax = gca; ax.YAxis.Exponent = 1; The above converts the y-axis to scientific notation but then incorporates a scale factor of x10^1. If I set the exponent to 0, it eliminates the scale factor, but then is also not in scientific notation.Location of y-axis tick marks and labels. This property controls where MATLAB displays the y-axis tick marks and labels. Setting this property to right moves the y-axis to the right side of the plot from its default position on the left side. See the plotyy function for a simple way to use two y-axes.

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.

The image function reverses the y-axis so I wanted to reverse it to correct it. I know it has something to do with gca but cannot figure out the right code.
