I want to do following tasks,

First generate a time series load data between 550-1000 for one day 30 min interval, so is load(48*1) dataset

then set level_1 = 750 and draw a line on the graph,

then find out the area above this level_1 line and area under seprate level (lets say level_2 = 600) line seprately

Try this:

t = 1:48; % Time Vector

load = randi(1000, 1, 48); % Create Data

level_1 = 750;

level_2 = 600;

above_level_1 = load >= level_1; % Logical Index Vector

area_1 = trapz(t(above_level_1), load(above_level_1)); % Area Under ‘Level_1’

below_level_2 = load <= level_2; % Logical Index Vector

area_2 = trapz(t(below_level_2), load(below_level_2)); % Area Under ‘Level_2’

figure

plot(t, load)

hold on

plot(xlim, [1 1]*level_1)

plot(xlim, [1 1]*level_2)

hold off
