How can I shading plot?

Hi everyone.

I want to make shading the color of the plotted functions. I explain: for example I plot many function on the same figure, and their colors are 'b', 'g', 'r', 'c' etc... I want them shading from dark green to light green (or other color).

Here an example: the normal plot

i want this...

Any clues?? Thanks to everyone

Color is defined as a vector of 3 values: RGB. When you select 'g' on you plots this vector is [0 1 0]. 'r' is [1 0 0] or 'b' is [0 1 0]. You can customize the color for every curve:

mycolor = [0 1 0];

h = plot(x,y);
set(h,'Color', mycolor);

To know which is the values of the greens, you can look at this page, for example: http://www.rapidtables.com/web/color/RGB_Color.htm

Thank you! Well, that's ok! But if i do multi plot like

 mycolor = [0 1 0];
 h = plot(x,y,x2,y2);
 set(h,'Color', mycolor);

the functions are all green. And there's no way to do this:

 mycolor = [0 1 0; 0 0.5 0];
 h = plot(x,y,x2,y2);
 set(h,'Color', mycolor);

it returns an error! Can i do this in other way? Thank you again!

You can do it on a loop. Let's say x an y are column vectors

X = [x, x2, x3];
Y = [y, y2, y3];
mycolor = [0 1 0; 0 0.5 0; 0 0.2 0];

figure
for it=1:size(X,2)
   h = plot(X(:,it), Y(:,it));
   hold on
   set(h,'Color', mycolor(it,:));
end

Thank you! that's good!
