my code:
for v = 1:7
s = spectra(:,v);
if speed(v)<= 0
plot(lambda,s,"--")
else
plot(lambda,s,"--","LineWidth",3)
end
hold on
end
hold off
It says incorrect for "Did you make a plot with seven line?" and I did? How can I fix this?

Hi Alyssa,
I understand that you are facing issue in completing the Project - Steller Motion II, task 4.
To my understanding, in the 4th task you are just required to plot graph with LineWidth 3, you need not to specify the type of line (here, dashed line)
You can refer to the following code:
for v = 1:7
s = spectra(:,v);
if speed(v) <= 0
plot(lambda,s,'--');
else
plot(lambda,s,'LineWidth',3);
end
hold on;
end
hold off;

i used below code got result all Pass
if not working, do multiple times of run and logout and login the cource . it amy work
for v = 1:7
s = spectra(:,v);
1<=1
if speed(v) <=0
plot(lambda,s,"--")
end
hold on
end

Use the code snippet below in [Task 2-4]
for c = 1:7
s = spectra(:,c);
if speed(c) <= 0
loglog(lambda, s, "--")
else
loglog(lambda, s, "LineWidth", 3)
end
hold on
end
hold off
xlabel('Wavelength') % Adding label for x-axis
ylabel('Intensity') % Adding label for y-axis

for v= 1:7
s = spectra(:,v);
if speed(v) <=0
plot(lambda,s,"--")
else
plot(lambda,s,LineWidth=3)
end
hold on
end
hold off
