Create offset in one of the 2 datasets

I have two files one .fig file and one .txt file

I know how to merge the two datasets. But how do I make an offset in time on the .txt file. I need to offset 6 sec and I have a log of each 2 mS

 figfile = 'IBox 100-100 - Copy.fig';
            datafile = 'V164_Backup_KK_Con_Test1_Step1_100_100_Rev1_removed_header.txt';
            fig = openfig(figfile);
            T = readtable(datafile,'Format','auto');
            T1 =T;
            T1.DCOUTPOWERKW = (T1.DCOUTV .* T1.DCOutA ./1000);
            T1.VFDPOWERKW = (T1.VFDV .* T1.DCOutA./1000);
            hold on
            t = T1.TIME;
            P = T1.Properties.VariableNames(2:end);
            for K = 1 : length(P)
                fn = P{K};
                plot(t, T1.(fn), 'DisplayName', fn);
            end
            hold off
            set(gcf, 'visible', 'on')
            legend show

hello

why not simply do

plot(t+6, T1.(fn), 'DisplayName', fn);

[Walter Roberson]

plot(t+seconds(6), T1.(fn), 'DisplayName', fn);

+6 would be adding 6 days.

When trying plot(t+seconds(6), T1.(fn), 'DisplayName', fn); I get the below error
"Data inputs must match the axis configuration. A numeric axis must have numeric data inputs or data inputs which can
be converted to double."

My inputfile contain one line for each 2mS see below (so I want to start with line 3300)

IMHO, t is a numeric array so it should be t+6 and not t+seconds(6)

I am just repeating myself

[Walter Roberson]

Yes, that does appear to be numeric time in seconds.

[Steen]

thanks it is working with t+6
