A=rand(10,10);
hold on
for i = 1:size(A,2)
plot(A(:,i))
hold on
end
Hello I store my data in a matrix, and I want to plot each colomn, I want to plot them in the colormap like this one, from purple to yellow, and give each color a legend, like "point 1", "point 2"
Also I know this could be bias, but I only have limited data, 10 points, anyway to smooth (interpolation) the line from the 10 ponts?

Ran in:
cmap = [ ...

67 3 158; ...
106 0 168; ...
145 14 163; ...

240 249 33; ...
]/255;
N = size(cmap,1);
A = (N:-1:1)+rand(N,1);
hold on
for ii = 1:N
plot(A(:,ii),'Color',cmap(ii,:));
end
legend(sprintfc('Point %c',64+(1:N)))
