Problem plotting a Grantt Chart

Hi all,

I'm trying to plot a Gantt chart to better read my results and i've been facing a problem,

So im plotting a scheduling problem where a task (my y-axis) is done in the time-window (x-axis) by a certain team of type z.

considering my p matrix where collumn 1 is the team that does the the task, collumn 2 the start period and collumn 3 the end period i've managed to create the chart i want with a problem: i cant turn certain teams invisible for each bar:

my code so far:

b=6;
e=8;
p=[6	1	5	0
    3	1	4	0
    1	1	3	1
    1	5	6	0
    1	3	5	1
    2	1	7	0];

D=zeros(b,e+1);
for i=1:b
    D(i,p(i,1)+1)=p(i,3)-p(i,2);
    D(i,p(i,1))=p(i,2);
end

hBar = barh(D,'stacked');
hBar(1).Visible='off';
yt = get(gca, 'YTick');
B=zeros(1,b);
C=zeros(1,e);
for i=1:b
    B(i)=i;
end
for i=1:e
    C(i)=i;
end
set(gca, 'YTick', yt, 'YTickLabel', {B})
size(D,1)

ans = 6

yjob(1)={''};
for i=2:e+1
    yjob(i) = {C(i-1)};
end
barbase = cumsum([zeros(size(D,1),1) D(:,1:end-1)],2);
joblblpos = D/2 + barbase;
for k1 = 1:size(D,1)
    text(joblblpos(k1,:), yt(k1)*ones(1,size(D,2)), yjob, 'HorizontalAlignment','center')
end

the result i get is this: (x marks the ones i wanted to remove to finish the chart) which is really close but not exactly

i there it even possible to do this? i went this way because i cant seem to make work of a way to name or color each bar individualy depending on the values of p(i,1) to easily see which team did what task.

Many thanks!
