Hey,
I am graphing two data sets that represent height, however one of the data sets has more x values than the other therefore making the scale look off when graphing both to compare them. How would I make the scale the same to be able to compare them on the same figure. I will attach pictures below.
figure;plot(h5(1449:end)/1000);
hold on;plot(-z{5}(714:end));

You need to use plot(x,y) instead of plot(y), where x is the vector of x-values at which you want to plot y. For example:
x1 = 1:100;
y1 = rand(1,length(x1)); % short dataset
x2 = 0.5:0.5:100;
y2 = rand(1,length(x2)); % long dataset
figure; hold on;
plot(x1,y1);
plot(x2,y2);

x1 = (h5(1449:end)/1000);
y1 = rand(1,length(x1)); % short dataset
x2 = (-z{5}(714:end));
y2 = rand(1,length(x2)); % long dataset
figure; hold on;
plot(x1,y1);
plot(x2,y2);
This is what I did, I'm not sure if this is what you meant, apologies I'm fairly new to Matlab. This is the graph that came out from the code above.
