How to shade area under 2D- curve into a certain x values

2 views (last 30 days)
Hi everyone! I need some help to fill my graphic! I researched for many examples, but any of them is working.
I wanted to fill the area bellow the curve into the X-value of 35 with one colour and bellow this level with another colour. I tried the functions fill and area, none of them worked.
The data is also attached to the question!
Thank you in advance!
clc
clear all
%% Set the Thresholds
highTOC = 35;
medTOC = 64;
Data = readtable('cl024_12._lab.txt');
L = Data.L;
Depth = Data.Depth;
%% correct the L* field measurements according to the calibration
Lmin_o = 0;%old minimum
Lmax_o = 100;%old maximum
Lmin_n = 26.6;%new minimum
Lmax_n = 99.6;%new maximum
NEWL = ((Lmax_n - Lmin_n)/(Lmax_o - Lmin_o)*L)+Lmin_n;
L_real = smooth(NEWL,15);
%%
figure(1)
plot(L_real,Depth)
baseval = 35;
hold on
area(min(L_real,baseval),Depth,baseval)
xlabel('L*','FontSize',12,'FontWeight','bold')
hold off
axis ij

Maybe something is wrong with importing? Try importdata
Data = importdata('cl024_12._lab.txt');
L = Data.data(:,5);
Depth = Data.data(:,1);
