MATLAB: Can i change the x axis without changing the plot? So i have a array with 10000 numbers in it, i want to plot thoes 10000 numbers in time, like 0-10sec insted of 0-10000.


buf = ones(10000,1)*nan;
i = 1; x = rand(10000,1);
for i <= 10000 buf(i,1) = x i = i+1; end plot(buf)

Best Answer

  • You just need to supply a vector of x values. Something like
    x = linspace(0, 10, length(buf));
    Then, just plot as
    plot(x, buf);
