The First image has the numbers 0 - 1386 on the y axis while the second has 812 - 849 on the y axis. I need the second scale on the first graph without having to modify the data in the graph as the data collapses into rows when i need it as shown in the first image.

Using Xtick & Xticklabel unfortunately does not scale the marks as seen in the second graph and either plots them all at the value on the original graph or modifies the graph with the new scale values only

have you tried xlim/ylim/zlim ?

I did. that changes the entire dataset being plotted. I am looking into the documentation link below to see if that works

Unfortunately, the yyaxis function was added in the 2016b version and I am working on the 2013b. Thanks for the information though

在 MATLAB Online 中打开

The axis values are set by the x and y values you use when plotting. Try just changing the y values:

x = 1600:10:2500;
y = 0:10:1386;
nx = length(x); ny = length(y);
z = rand(ny,nx);
surf(x,y,z);

vs

y = linspace(812,849,ny);
surf(x,y,z);

I need the y values to create the graph. If I change the y values, the plot changes and does not represent the data in the format I need. However, the y values are also associated with other data and I would like to be able to plot the same y values but show the other data as a reference(ideally on the scale).
