Found out that I had to include both columns in when selecting which parts of ts1.Data to plot. This line of code gives me what I want (I realise greater than 1 second means > 1, not >2 as earlier - my mistake). Please close this question.
plot(ts2.Data(ts2.Time > 2, :)) %plots all lines greater than 2 seconds
ts2.Data(:, 3) %gives me Data:3 column
