load and plot many .mat files in a loop

Hi, i have many .mat files which i would like to plot in the same figure. The problem is my data are not loading in my for loop:

close all
clear all
clc

load('C:\ordner1\ordner2\tc.mat');
Path='C:\ordner1\ordner2\Station_01\hhz';     
P=strcat(Path,'\PSDPDFs\1120\')     %P=strcat(Path,'\hhe\06\');
S=(fullfile(P,'*.mat'));
AllFiles=dir(S);

for kk=1:5    %numel(AllFiles)
  File3=AllFiles(kk).name;
  Data = load(File3);   %load(strcat(P,File3));
  semilogx(tc,Data.Z3)
  hold on
end
 
xlabel('Period (s)')
 ylabel('Power 10*log10 (m/s^2)/Hz or dB')
 title('PSDPDF diagram containing 1 month of Data composed of 1 Hour segments')
 axis tight
 
 hold off
 
 

as i said i become an error with the load function:

 Error using load
Unable to read file 'PSDPDF1.mat'. No such file or directory.

Error in plot_PSDPDF (line 13)
  Data = load(File3);   %load(strcat(P,File3));
  
  

i try another code by changing load(File3) with load(strcat(P,File3)):

  close all
clear all
clc

load('C:\ordner1\ordner2\tc.mat');
Path='C:\ordner1\ordner2\Station_01\hhz';     
P=strcat(Path,'\PSDPDFs\1120\')     %P=strcat(Path,'\hhe\06\');
S=(fullfile(P,'*.mat'));
AllFiles=dir(S);

for kk=1:5    %numel(AllFiles)
  File3=AllFiles(kk).name;
  Data=load(strcat(P,File3));
  semilogx(tc,Data)
  hold on
end
 
xlabel('Period (s)')
 ylabel('Power 10*log10 (m/s^2)/Hz or dB')
 title('PSD diagram containing 1 month of Data composed of 1 Hour segments')
 axis tight
 
 hold off
 
 

i got another error message:

 Error using semilogx
Unrecognized property PSDPDF for class Line.

Error in plot_PSDPDF_220624 (line 14)
  semilogx(tc,Data)
  
  

can someone help me with that

Try it like this

Data=load(strcat(P,File3));
semilogx(tc,Data.Z3)

Somehow you dropped off the .Z3 when you tried this

Data=load(strcat(P,File3));
semilogx(tc,Data)

ooh I forgot to say, i did try it too, i got the following msg:

Unrecognized field name "Z3".

Error in plot_PSDPDF_220624 (line 14)
  semilogx(tc,Data.Z3)

 

Data should actually be my psdpdf (97,1) mat file but instead of that i get this:

  Data = 

  struct with fields:

    PSDPDF: [97×1 double]

[Voss]

Data=load(strcat(P,File3));
semilogx(tc,Data.PSDPDF)
