Kind of looks like a scatter plot. You can try this:
%%Load data
data = load('Tc1.mat');
Tc1=data.Tc1;
t=Tc1.t
%%time of day (y)
y=duration([hour(t) minute(t) second(t)])
%%date (x)
x=datetime(year(t),month(t),day(t))
%%color (z)
[z,groups]=findgroups(Tc1.Column1streamId);
scatter3(x,y,z,[],z)
xtickformat('MMM-dd')
view([0 90])
set(gca,'xtick',unique(x))
Obviously it will look more similar when you have more days.
