How can i change colors of data in a 2D plot?

hi, i am making a 2D plot and have multiple data which i want to be different colors. i used colormaps (lines, parula, prism).. but proble with them is after 3-4 data points the same color gets repeated again and again, and i not able to distinguish between data? can anyone help?

Thanks

The colors of lines made using plot() function is decided by the ColorOrder property of axes not Colormap.

One way is to increase the colors in the ColorOrder property of the axes. For example, try

rng(0);
ax = axes();
ax.ColorOrder = rand(100, 3);
hold(ax);

%% now run the plot commands.

Thank you Ameer. it works but its random every time i generate the plot. Can i make it the color consistent for every time i generate the plot because i am generating other plots too for the different data but colors needs to be consistent on every plot.

Add

rng(0)

at the beginning of the code. It will seed the random number generator with same value and the results will be consistent.
