Plotting a continuous line from separate data files

Having an issue with some velocity profile plots I am trying to make. I have 9 data files, and have been plotting using the very basic code below. Only, the plot generated has 9 different line segments which do not connect and have different colours. I would like to plot one continuous line in a single colour. Can anyone offer any insight?

folder = xxxxxxxxxx

file = '20percent_00_20.185.19.Vectrino Profiler.00000.mat';

Combine all of them in one vector before plotting. If they are line-vectors:

x_data = [x1 , x2 , x3 ... x9];
y_data = [y1 , y2 , y3 ... y9];
plot(x_data,y_data);

If they are columns, instead of using "," to concatenate the vectors, use ";".
