2D information to 1D colorplot

I want to plot a line (which can be a thick line) in which I plot for every x the temperature as the color, so I want a 1D graph in which the color says the temperature on that place, is that possible?

may help, if you are happy enough to have a surface object rather than a line object. It still looks like a line, just has surface properties so is a little less easy to do any further manipulations to if you need to.

Simple example

x = 0:10;
y = x.^2;
temp = rand(1,10);        % temperature
cm = jet(10);             % colormap
ind = 1+round(temp/max(temp)*9);    % convert temperature to color index
figure(1)
hold on
for i = 1:length(x)-1
    plot(x(i:i+1),y(i:i+1),'color',cm(ind(i),:))
end
hold off
