StackedPlot with separate events

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.

Awesome, thank you!

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')

Ideally I'd like to keep the stacked plot format to interactively examine various plot values at the same x-axis position, but you nailed the aesthetics of what I'm after!

Thanks, alex

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.

Ok, thanks a lot!
