MATLAB: Is the autocolor green of plot not the same as plotting ‘g’

autocolorcolorgreenplot

Why don't

plot(x1,y1,x2,y2)

and

plot(x1,y1,'b',x2,y2,'g')

have the same color green line? Can you make them the same color? All the other colors that can be specified as a character seem to produce the same color as the autocolor of plot().

I have no idea why, but you can set the colour manually:

plot(x,y,'color',[0 0.5 0])

or, for that matter, use any 1x3 vector to set the RGB colours. Type

 get(gcf,'DefaultAxesColorOrder')

to see the default colour scheme

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

MATLAB: How to do plotting with different colors in same figure

Hi!

If you plot like

plot(x,y)

and y is a matrix, you get plots with different color automatically. But you can do something like this to get manual coloring:

colorstring = 'kbgry';
figure(1); cla;
hold on
for i = 1:5
  plot(x,y(:, i), 'Color', colorstring(i))
end
