How can I set different colors for different lines in a plot?

Hi,

I have a vector of values named result, that indicates the color intensity of each pixel on the same vertical line on a image. I want tp plot it now with a colorbar. For the colorbar I defined the colors needed in the matrix colors. I used scatter to plot each point of result with its corresponding color and I connected all point using line().

That works well. Now I want to draw vertical line for each point and each line has to have the color of the corresponding point.

How can I do it?

Here is my code:

%defining the colors
image = imread('color_deg.jpg'); % image containing all colors needed
size_image = size(image);
ln = size_image(1);
colors = zeros(ln, 3);
% set all color values
for i=1:ln
        vector = squeeze(image(i,10,:));
        colors(i,:) = vector;
end

x = 1:1:size_result(2); %vector who has the lenght of the y-axis [1 2 3 ... s(2)]
ss = 50;
Color1 = colors/255;

fig = figure
colormap(Color1);
h=scatter(x,result,ss,result,'filled')
line(x,result) %connect all points
%draw vertical lines
for i=1:s(2)
    line([i i],[0 result(i)])
end
colorbar
caxis([0 170]);

Here is an example of what my program can do now. I just want to set the colors for the vertical lines

Example:

a = line(x,y) % a is the handle to my line object
a.Color = [1 0 0] %red
%or you can do:
set(a,'Color',[1 0 0])

Thanks for your answer Kevin. But the color that I need is saved in the matrix Color1. The problem is that I can't kwon from wich line of the matrix it is. Is there any possibility to get the color of the points from the scatter plot or from the colorbar?
