Hi all,
From the codes below I graphed 2 data sets on the same plot. I found the max height and min height for both plots but i've been trying to figure out how to plot on the graph the max point and min point. Any recommendations?
clear
clc
close all
f = 120;
data1 = load('trial1.txt');
data2 = load('trial2.txt');
t1 = [1/f : 1/f : length(data1)/f]; %divide f for sampling step size
t2 = [1/f : 1/f : length(data2)/f];
plot(t1,data1)
maxHeight1 = max(data1)
minHeight1 = min(data1)
hold on
plot(t2,data2)
maxHeight2 = max(data2)
minHeight2 = min(data2)
hold off
xlabel('Time (s)')
ylabel('Height (m)')
title('Time vs Height')
legend('Data Set 1', 'Data Set 2')

You can do that by using Markers Detail here
plot(x,y,'-p','MarkerIndices',[idxmin idxmax],'MarkerFaceColor','red','MarkerSize',15)
