Dear All,
I was create code for plotting the data. But I do not know why in my legend the color do not folow as graphh. There are missing color yellow, black and magenta.
all the data i was attached here
clc
close all
clear all
LD = load('xstats.mat'); %xstats.mat can get from imtool3D
xstats = LD.xstats
LD = load('ystats.mat'); %ystats.mat can get from imtool3D
ystats = LD.ystats
F = openfig('L1.fig');
Lines = findobj(F, 'Type','Line');
x = Lines.XData;
y = Lines.YData;
wx = fwhm(x,y)
[wm,xr,hm] = myFWHM(x,y)
[ymax,idx] = max(y);
ymin = min(y);
hold on
plot(x, y)
plot(xr, [1 1]*hm+ymin, '.-r')
hold off

Hi,
I understand that you want the legends to match the graphs.
To achieve this, ensure that you save the plot handles(h1,h2,h3,h4) in variables, which you can then use in the 'legend' function.
Here is the code sample for 4 plots:
hold on;
h1 = plot(x1, y1, "LineStyle", "--", "LineWidth", 1, "Color", "g");
plot(xr1, [1 1]*hm1 + ymin1, '.-g');
text(x1(idx1), hm1 + ymin1, sprintf(' %.3f', wm1), 'Horiz', 'center', 'Vert', 'bottom');
h2 = plot(x2, y2, "LineStyle", "--", "LineWidth", 1, "Color", "r");
plot(xr2, [1 1]*hm2 + ymin2, '.-r');
text(x2(idx2), hm2 + ymin2, sprintf(' %.3f', wm2), 'Horiz', 'left', 'Vert', 'bottom');
h3 = plot(x3, y3, "LineStyle", "--", "LineWidth", 1, "Color", "black");
plot(xr3, [1 1]*hm3 + ymin3, '.-black');
text(x3(idx3), hm3 + ymin3, sprintf(' %.3f', wm3), 'Horiz', 'center', 'Vert', 'bottom');
h4 = plot(x4, y4, "LineStyle", "--", "LineWidth", 1, "Color", "yellow");
plot(xr4, [1 1]*hm4 + ymin4, '.-yellow');
text(x4(idx4), hm4 + ymin4, sprintf(' %.3f', wm4), 'Horiz', 'center', 'Vert', 'bottom');
hold off;
grid on;
% Add legend for the primary lines using handles
legend([h1, h2, h3, h4], 'FWHM Line Source 1', 'FWHM Line Source 2', 'FWHM Line Source 3', 'FWHM Line Source 4');
Hope this solves!
