how to solve this error index?

i Have five files i have to plot 50 percentile plot column 3 data with respect to 120:0.1:150.5 in one single plot

Files = dir('*.csv');
Filesc = struct2cell(Files);
NrFiles = size(Filesc,2);
for k = 1:NrFiles
    filename = Filesc{1,k};
    T{k,:} = readtable(filename);
    end
Final_T = cat(1,T{:});
i=reshape(Final_T.r,5,24)   

i = 5×24

i am not able to plot properly 50 percentile plot for column 3 data which is present in all data files wrt 120:0.1:124.6 in one single plot . i want all the files data in one plot

This looks strikingly similar to how to import file? and I still do not understand the objective.

this time data s changed i have to plot 50 percentile column 3 data of all files wrt 120:0.1:124.6
