The graph that I plotted using the following line looks like crayon.
plot(this_t_vec,sq(nanmean(rep_avg(:,:,cond(plot_loop),:,:),5)),'Color',c(c_inc,:),'linewidth',2);
The colour is fine when I plot random stuff e.g. plot(rand(10)).
Your help is deeply appreciated.

Hi @darova, I want the colour to look normal instead of crayon-like. Any setting or code that I can adjust so that the graph doesnt look pixelate?

The graph color is based on the value you set for the property 'Color'. Based on the given information, you are setting your 'Color' property to a variable (c_inc,:). You can set the 'Color' property to [1 0 0] for red color. You may refer to the 'Color' property in the below link

Thank you for your answer Chidvi. I reckoned the problem is with my dataset, and not the color setting. Even if I use [1 0 0], the colour is still crayon-like.

Try linesmoothing
clc,clear
x = 0:10;
y = sin(x);
plot(x,y,'linesmoothing','on')

I had a similar problem with slightly noisy data. It was mostly solved by setting the custom renderer of the figure to painters: (In the figure window: File>Export setup>Rendering>Tick custom renderer>Dropdown select painters (vector format) if its not the default.)
