You could create your own Gantt chart by building on this quick demo below.
Demo: Matrix version
data = [% task, start, finish
1 0 410
2 410 600
3 600 803
4 803 1425
5 600 950
6 0 653
7 653 1970
8 1970 3050
9 3050 3406
10 3406 3778
11 3778 4192
12 4192 4693
13 4693 5353
14 3050 4572
15 5353 5452
16 5452 7648];
width = .75; % vertical width of horizontal bars
ypairs = data(:,1) + width./[-2,2];
y = repelem(ypairs,1,2);
x = data(:,[2,3,3,2]);
patch(x',y','b')
grid on
set(gca,'YDir','Reverse')
Demo: Table version
T = array2table([
1 0 410
2 410 600
3 600 803
4 803 1425
5 600 950
6 0 653
7 653 1970
8 1970 3050
9 3050 3406
10 3406 3778
11 3778 4192
12 4192 4693
13 4693 5353
14 3050 4572
15 5353 5452
16 5452 7648], ...
width = .75; % vertical width of horizontal bars
y = repelem(ypairs,1,2);
x = [T.Start, T.Finish, T.Finish, T.Start];
patch(x',y','b')
grid on
set(gca,'YDir','Reverse')
