hello, i have a dataset with home activities, i need a way to represent the action like in the picture. When the action is running, in this time laps i have 1 as value. when the action isn't running, the time laps represented by 0 as value; but i don't find a solution to rappresent my dataset as in the picture. I've made three different tables where data is organized in different way, tryng to find a solution. Thanks, i'm new in matlab.

Your data is best represented as a timetable in MATLAB. You can then use stackedplot to generate the visualization.

haa = readtimetable('Home_actionAll.csv');

haa = haa(:,{'Bed_to_Toilet_begin', 'Leave_Home_begin', 'Sleep_begin'}); % the begin variables seem to already capture the information, throw away the rest

haa = varfun(@(x)x>0, haa); % normalize to 0s and 1s

haa.Properties.VariableNames = {'Bed_to_Toilet', 'Leave_Home', 'Sleep'}; % fix the variable names

haa.Properties.VariableContinuity = {'step', 'step', 'step'}; % set continuity such that stairs plots are plotted

sp = stackedplot(haa);

Zooming in shows the stairs better:

wow, that's fine thanks, in a week i tried a lot of things.

you know a way to eliminated the small steps, like eliminated the action with a duration less than 2 minutes?

i've found this code

MMRT=readtable(Home_ActionAll.csv)
C=(MMRT.Date1(MMRT.Leave_Home==1));                                      
D=(MMRT.Date1(MMRT.Leave_Home==2)); 
Home=array2table(CD);
Home.Properties.VariableNames([1 2])={'Start' 'End'};
Home.Duration=Home.End-Home.Start;
Home=sortrows(Home);                                                      
Home.ID(:)=(2)
Home.Duration1=datenum(Home.Duration);                                     
Home(Home.Duration1<0.001,:)=[];
