Plotting a logical function if a value is greater than 0

I'm trying plot a logical input over the course of the time vector tor, where as long if the function is true, then I would plot a solid line, if false it wouldn't plot anything. I have 6 different inputs that I need to make the comparison for listed in the ordinal, but I don't know how to plot that logical value over the course "tor". Can anyone help?

if real(s1.*conj(s2))>0;
    AG = true();
    figure
    plot(tor,AG)
    y = ordinal({'AG', 'BG', 'CG', 'AB', 'BC', 'CA'})
end

Thanks

Something like this?

tor=1:10;
AG=tor>5;
y=double(AG); y(~AG)=nan;

h=plot(tor,y);
xlim([min(tor),max(tor)]);xlabel 'tor', ylabel 'y'

[Wesley Murar]

I need the y-axis to be the following values:

AG, BG, CG, AB, BC, and CA

Then if real(s1.*s2(conj)) > 0, then plot that with a solid line for the respective y-axis variable as shown in the picture.

Yes, I was careful to arrange that the Y axes values would be those values.

torvals = linspace(0,6);
ntor = length(torvals);

C = categorical(nan(ntor,1), (1:6),{'AB', 'BC', 'CA', 'AG', 'BG', 'CG'}, 'ordinal',true);

ABvals = C;
BCvals = C;
CAvals = C;
AGvals = C;
BGvals = C;
CGvals = C;

for toridx = 1 : ntor
   tor = torvals(toridx);
   %stuff here based on tor
   if real(s1.*conj(s2))>0
      AGvals(toridx) = 'AG';
   end
end

h = plot(torvals, [ABvals, BCvals, CAvals, AGvals, BGvals, CGvals]);
h(4).Color = [0.5, 0, 0.5];  %purple
