Too many dimensions error msg in figure

I get the message "Error using plot Data may not have more than 2 dimensions" when running the follwoing commands:
Alder = {'<20', '2029','3039','4049','5059','6069','>70', 'all'};
Vars = {AlG, AlR, AlI, AlDI, AlBV};
Vars2 = {'AlG', 'AlR', 'AlI', 'AlDI', 'AlBV'};
Aar = {'2011', '2012', '2013_1', '2014_1', '2014_s2', '2014_s5'};
n = length(Vars);
nAar = length(Aar);
nAl = length(Alder);
numberOfColors = nAl;
myColorMap = lines(numberOfColors);
for iVars = 1:n;
aVars = Vars{iVars};
figure,title(Vars2{iVars});
hold on
for iAl = 1:nAl
plot(aVars(11,iAl,:), 'color', myColorMap((iAl), :));
set(gca, 'XTickLabel',Aar)
legend((Alder),'location','NE','FontSize',10);
end
hold off
end
plot(aVars(11,1,:), 'color', myColorMap((iAl), :));
All matrices inn "Vars" is 11x8x6 matrices. I don't understand why the above commands fails, since almost the same commands work in this case below. The only difference is that in the above script I have "Alder" on the x-axis and in the below script I have "Aar" on the x-axis.
Alder = {'<20', '2029','3039','4049','5059','6069','>70', 'all'};
Vars = {gjG, gjR, gjI, gjDI, gjBV, GtoDI, GtoBV, RtoDIplusR, ItoG, RtoG, GtoI};
Vars2 = {'gjG', 'gjR', 'gjI', 'gjDI', 'gjBV', 'GtoDI', 'GtoBV', 'RtoDIplusR', 'ItoG', 'RtoG', 'GtoI'};
Aar = {'2011', '2012', '2013_1', '2014_1', '2014_s2', '2014_s5'};
n = length(Vars);
nAar = length(Aar);
numberOfColors = 6;
myColorMap = lines(numberOfColors);
for iVars = 1:n;
aVars = Vars{iVars};
figure,title(Vars2{iVars});
hold on
for iAar = 1:nAar
plot(aVars(11,:,iAar), 'color', myColorMap((iAar), :));
set(gca, 'XTickLabel',Alder)
legend((Aar),'location','NE','FontSize',10);
end
hold off
end

plot( squeeze(aVars(11,iAl,:)), 'color', myColorMap((iAl), :));
In the first one you had a 3D matrix accessed at (specific value, specific value, :) . In MATLAB the result of that would be 1 x 1 x N, a 3D result. MATLAB cannot plot 3D vectors.
In the second one you had a 3D matrix accessed at (specific value, :, specific value). In MATLAB the result of that would be 1 x N x 1 and then the trailing 1's get dropped, leaving 1 x N which is a 2D result; MATLAB is able to plot with 2D vectors.
The squeeze() I added above transforms the 3D vector into a 2D vector.
