I have 6 data sets in a plot for which I only want to show 3 in my legend, because the other 3 are just fits. If anybody can show me how to skip data sets in the legend I'd appreciate it!
This is my code (I will also attach it):
clear; clc; clf; close all;
x1 = [0.015 0.020 0.050 0.100 0.200 0.300 0.400 0.500];
y1 = [5.518E-11 7.215E-11 1.832E-10 3.824E-10 7.328E-10 1.127E-09 1.472E-09 1.831E-09];
y1_fit = [5.4986E-11 7.3391E-11 1.8408E-10 3.6907E-10 7.3998E-10 1.1116E-09 1.4836E-09 1.8560E-09];
x2 = [0.015 0.020 0.050 0.100 0.200 0.300 0.400 0.500];
y2 = [4.881E-11 7.215E-11 1.505E-10 2.299E-10 2.885E-10 5.622E-10 3.367E-10 5.284E-10];
y2_fit = [5.935E-11 7.128E-11 1.277E-10 1.986E-10 3.087E-10 3.997E-10 4.800E-10 5.533E-10];
x3 = [0.015 0.020 0.100 0.200 0.300];
y3 = [1.6010E-11 2.7611E-11 1.2114E-10 2.1066E-10 3.6957E-10];
y3_fit = [1.7010E-11 2.2611E-11 1.1114E-10 2.2066E-10 3.2957E-10];
loglog(x1, y1, 'bo', x1, y1_fit, 'b-')
hold on
loglog(x2, y2, 'ro', x2, y2_fit, 'r--')
loglog(x3, y3, 'go', x3, y3_fit, 'g--')
grid on
hold off
legend('data 1', 'skip this', 'data2', 'skip this','data 2', 'skip this')
