the colors red, blue, yellow repeated again in my plot, how I can give each curve in the plot different color

clc;

clear;

K=1:30;

for i=1:10

C_T=i*log(K);

plot_T = plot(K,C_T,'-O','LineWidth',2);

hold on

grid on

title('Total Capacity of the System')

xlabel('Number of Users')

ylabel('Total Capacity (bit/s/Hz)')

legend

end

One way is to specify a different color in each call to the plot function:

K=1:30;
for i=1:10
    C_T=i*log(K);
    plot_T = plot(K,C_T,'-O','color', rand(1,3), 'LineWidth',2); % use custom color
    hold on
    grid on
    title('Total Capacity of the System')
    xlabel('Number of Users')
    ylabel('Total Capacity (bit/s/Hz)')
    legend
end

Below is some modified code that increases the number of colors from 7 to 10. The additional colors are random, but you can set them to particular colors if you wish.

ax = gca;
ax.ColorOrder(8:10,:) = rand(3,3); % increase from 7 to 10 colors
hold on;
K=1:30;
for i=1:10
    C_T=i*log(K);
    plot_T = plot(K,C_T, '-O', 'LineWidth', 2);
    hold on
    grid on
    title('Total Capacity of the System')
    xlabel('Number of Users')
    ylabel('Total Capacity (bit/s/Hz)')
    legend
end
