I'd like to make a stacked plot with each plot showing different events (each plot's own events only). How could I fix this code to show only the proper data's corresponding events? (apologies for my clumsy coding)

%make timetable

times=[1, 2, 5]';

s=seconds(times);

variable=[3, 4, 5]';

T=table(s,variable);

TT=table2timetable(T);

%makes event table

EventTime = seconds(4);

lengths = seconds(1);

Events = eventtable(EventTime,EventLengths=lengths);

%Assign event table to time table

TT.Properties.Events=Events;

%make timetable

variable2=[6, 8, 9]';

T2=table(s,variable2);

TT2=table2timetable(T2);

%makes event table

EventTime2 = seconds(1);

lengths2 = seconds(1);

Events2 = eventtable(EventTime2,EventLengths=lengths2);

%Assign event table2 to time table2

TT2.Properties.Events=Events2;

stackedplot(TT,TT2)

Hi Alex, I have submitted an Enhancement Request on your behalf to the relevant development team to support this functionality in a future update or release of MATLAB.

Maybe something like this is good enough:

%make timetable

times=[1, 2, 5]';

s=seconds(times);

variable=[3, 4, 5]';

T=table(s,variable);

TT=table2timetable(T);

%makes event table

EventTime = seconds(4);

lengths = seconds(1);

Events = eventtable(EventTime,EventLengths=lengths);

%Assign event table to time table

TT.Properties.Events=Events;

%make timetable

variable2=[6, 8, 9]';

T2=table(s,variable2);

TT2=table2timetable(T2);

%makes event table

EventTime2 = seconds(1);

lengths2 = seconds(1);

Events2 = eventtable(EventTime2,EventLengths=lengths2);

%Assign event table2 to time table2

TT2.Properties.Events=Events2;

f = figure();

tl = tiledlayout(f,2,1);

ax = gobjects(1,2);

h = gobjects(1,2);

col = colororder(f);

ax(1) = nexttile(tl);

h(1) = plot(TT.s,TT.variable,'Color',col(1,:));

xregion(ax(1),Events.Time,Events.Time+Events.EventLengths);

ylabel(ax(1),'variable','Rotation',0);

ax(1).Box = 'off';

ax(1).XAxis.Visible = 'off';

ax(2) = nexttile(tl);

h(2) = plot(TT2.s,TT2.variable2,'Color',col(2,:));

xregion(ax(2),Events2.Time,Events2.Time+Events2.EventLengths);

ylabel(ax(2),'variable2','Rotation',0);

xlabel(ax(2),'s');

ax(2).Box = 'off';

legend(h,{'TT','TT2'},'Location','NorthOutside','Orientation','horizontal')

linkaxes(ax,'x')

Unfortunately, MathWorks doesn't allow us much customization of stackedplots at the present time. Maybe someone else can share a workaround using a stackedplot.

Note that in my answer, all the axes are linked in the 'x' dimension (linkaxes(ax,'x')), so when you zoom/pan on one axes, the others will update automatically. It may not be as useful as the "linked datatip" you'd get in a stackedplot, but it may be of some use.
