%   "Produce a single plot containing the horizontal displacement
%   as a function of time from the recorded data"
x = 1:0.01:10
y = x.^2
z = x.^3
a = plot(x,y,x,z)
xlabel('Time (seconds)')
ylabel('Horizontal displacement (m)')
title('Part 5')
legend('Attempt 1', 'Attempt 2')
saveas(a,'Plot 5.jpg')

Trying to save a plot with multiple inputs into a jpg file. Unable to do so. Can someone please help

Hi Joshua!

saveas needs a figure handle to save. assigning a to the output of plot gives you a line instead. Fix it with this:

%   "Produce a single plot containing the horizontal displacement
%   as a function of time from the recorded data"
x = 1:0.01:10;
y = x.^2;
z = x.^3;
a = figure;
plot(x,y,x,z)
xlabel('Time (seconds)')
ylabel('Horizontal displacement (m)')
title('Part 5')
legend('Attempt 1', 'Attempt 2')
saveas(a,'Plot 5.jpg')
