I do not understand the question. Please explain better. What is "Reward per Episode" and "Number of Episodes"?

What does the averaged line and noisy signal represent?

Color settings of WHAT? Same color as WHAT?

Try this:

brightBlue = [0,0,1];        % High intensity
darkBlue = brightBlue / 2;   % Low intensity is half as bright.
plot(x, y, 'Color', brightBlue);
hold on;
plot(x, smoothed_y, 'Color', darkBlue, 'LineWidth', 2);

This is not an answer.

I did give an answer though in my Answer just above. Is there anything wrong with it? If so, say what is wrong with it.
