matrix per minute in plot per hour

I have a load profile matrix 96x1, a value for every 15min..

But I want to plot this in a graph with the plot figure of the 15min. data but with the x axis labeled in hour (per 4 values 1 indicator on the x axis, starting from 0 to 24h.

Can this be done?

you mean something like that? or do you want another format?

plot((1:96)/4,rand(96,1));
xticks(0:3:24)
xlim([0 24]);
xlabel('time / h')

exactly this. probably a stupid question but I couldn't get it to work. Thanks for the help!

Something like this?

for k = 0:20
    x = minutes(15*k + linspace(0,15,96));
    y = cumsum(rand(96,1));
    p = plot(x,y);
    hold on
end
ax = gca;
ax.XAxis.TickLabelFormat = 'h';
ax.XAxis.MinorTickValues = hours(0:0.25:24);
ax.XAxis.MinorTick = 'on';
