COLOR CODE IN MULTIPLE PLOT

Hi everyone, I inted to to make a multiple plot with with predefined color code.

Could you please assit me, on how to include the code to define the colors of my plot instead of using the matlab default color

clear all; close all; clc
a=[6.5 10 12 16];b=linspace(1, 10);

for i=1:4;
    aa=a(i)
    y=1./(exp(-aa./b)+ 1);
    plot(b, y)
    hold on
end

If you are using a new enough version of MATLAB, see colororder

If you are using an older version of MATLAB, you could change the ColorOrder property of the axes.

Or... each time you plot() you could pass in a 'Color' option with the color you want. For example,

cmap = jet(4);

a=[6.5 10 12 16];b=linspace(1, 10);

for i=1:4;
    aa=a(i)
    y=1./(exp(-aa./b)+ 1);
    plot(b, y, 'color', cmap(i, :), 'DisplayName', string(i));
    hold on
end

aa = 6.5000

aa = 10

aa = 12

aa = 16

Thank you Walter for your reply..

Actuually, I want to specify the color code.

For example 'r' '-k' 'g' and '-b'.

How can I achieve this?

Thank you

How can i do it pls?

[Walter Roberson]

cc = {'.r', '-k', '--g', ':b'};
a = [6.5 10 12 16]; b = linspace(1, 10);
for i=1:4;
    aa=a(i)
    y=1./(exp(-aa./b)+ 1);
    plot(b, y, cc{i}, 'DisplayName', string(i));
    hold on
end

aa = 6.5000

aa = 10

aa = 12

aa = 16
