Plots: aligning categorical y-axis labels

Hi Everyone,
I'm trying to plot a set of error bars with corresponding, categorical labels shown on the right-side (Y2) axis:
% create dummy data
y = [1,2,3];
x = [5,10,20];
err = 0.5*ones(size(y));
% draw plot
figure(1)
yyaxis right
errorbar(x,y,err,'.b','horizontal')
xlim([0 30])
ylim([0 4])
% hide Y1 axis
hax = gca;
hax.YAxis(1).Visible='off';
% add categorical labels to Y2 axis
hax.YAxis(2).TickLabels = {'Label one','Label two','Label three'};
Instead of repeated Y2 labels of 'Label one', 'Label two', 'Label three' I would like each label to be used once - opposite each of the error bars. That is at the positions specified by y.
Any help with this would be much appreciated! Many thanks.

% hide Y1 axis
hax = gca;
hax.YAxis(1).Visible='off';
% add categorical labels to Y2 axis
hax.YAxis(2).TickValues = y; %<<<< Add this to specify where the ticks (and hence the labels) are located
hax.YAxis(2).TickLabels = {'Label one','Label two','Label three'};

Set the yticks using the values in y and modify the yticklabels of the right y-axis accordingly -
If the order of labels is expected to be reverse of that is displayed below, flip the variable str to reverse the order.
% create dummy data
y = [1,2,3];
x = [5,10,20];
err = 0.5*ones(size(y));
% draw plot
figure(1)
yyaxis right
errorbar(x,y,err,'.b','horizontal')
yticks(y)
str = {'Label one','Label two','Label three'};
yticklabels(str)
xlim([0 30])
ylim([0 4])
% hide Y1 axis
hax = gca;
hax.YAxis(1).Visible='off';
