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?
clearvars
folder = xxxxxxxxxx
file = '20percent_00_20.185.19.Vectrino Profiler.00000.mat';
load(fullfile(folder, file))
U00 = Data.Profiles_VelX;
clear Data Config file
file = '20percent_20_40.185.19.Vectrino Profiler.00000.mat';
load(fullfile(folder, file))
U20 = Data.Profiles_VelX;
clear Data Config file
file = '20percent_40_60.185.19.Vectrino Profiler.00000.mat';
load(fullfile(folder, file))
U40 = Data.Profiles_VelX;
clear Data Config file
file = '20percent_60_80.185.19.Vectrino Profiler.00000.mat';
load(fullfile(folder, file))

file = '20percent_80_100.185.19.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 ";".
