DOES ANYONE KNOW WHY NOT ALL THE DATA APPEAR IN THE GRAPH?

1 view (last 30 days)
Hello everyone,
when I go to plot the average with different colors ,not all the data appear in the graph.
As you can see in the attached image, I only get some data (but not all data) which are present in the matrix (in the blue circle should be the data that don't appear)
While if I go to plot just the average, I get all the data in the graph.
This happens just when I plot the data with different colors, not when I simply plot the data ("% Plot Average).
%PLOT average with different colors for each bar
load('giulia_sd_med_rialz_7.mat')
errorbar(giulia_daily.Time(1:4471,1),giulia_sd.Var8(1:4471,1),giulia_sd.Var7(1:4471,1),'.r','MarkerSize',6)
errorbar(giulia_daily.Time(4471:4779,1),giulia_sd.Var8(4471:4779,1),giulia_sd.Var7(4471:4779,1),'.b','MarkerSize',6)
errorbar(giulia_daily.Time(4779:7722,1),giulia_sd.Var8(4779:7722,1),giulia_sd.Var7(4779:7722,1),'.r','MarkerSize',6)
hold on
plot(giulia_daily.Time(:,1),[B, giulia_sd.Var8(:,1)]);
xlabel('Time');
ylabel('Height(cm)');
title('Giulia');
Does anyone know how to solve this problem?
Thank you.

Because there are many "nan" points in giulia_daily and therefore, your plots have many missing points.

You do a lot of filtering of spikes. How would we know which data is "missing" compared to which data you deliberately set to nan?
Your code to get rid of the spikes is not sustainable. I attach a rewritten version of it.
load('giulia_TT.mat')
load('giulia_sd_med_rialz_7.mat')
giulia_daily=retime(giulia_TT,'daily','mean');
%MEDIANA_FILTER
Mediana_Filter = medfilt1(giulia_daily.Var5(:,1),7);
% PLOT_MEDIAN_FILTER
plot(giulia_daily.Time(:,1),[giulia_daily.Var5(:,1) Mediana_Filter]);
med=Mediana_Filter;
% FILTER_SPIKES

mask = false(nmed,1);
for K = 1 : size(zaps,1)
mask = mask | (ismember(I, zaps(K,1):zaps(K,2)) & med >= zaps(K,3));
end
med(mask) = nan;
plot(giulia_daily.Time(:,1),[giulia_daily.Var5(:,1) med]);
A=med;
for i =3639:7722
A(i)=A(i)+40;

plot(giulia_daily.Time(:,1),[giulia_daily.Var5(:,1) A]);
