How can i put the same labels also on both left and right Y axes (tried several solutions but can't make them work as I wish)?
boxplot(rand(100,10))
Thanks
Oleg

I can only think of a workaround...
EDIT: Per Oleg's comment, I've added a "ResizeFcn" for the figure to adjust the axes properties when the figure is resized.
EDIT 2: Added zoom post action so that the tick labels update upon zoom as well.
function boxplot_test
boxplot(rand(100,10));
ax1 = gca;
ax2 = axes('Position', get(ax1, 'Position'), ...
'Color', 'none', 'YAxisLocation', 'right', ...
'XTick', [], 'YTick', get(ax1, 'YTick'), ...
'YLim', ylim(ax1), 'HandleVisibility', 'off');
uistack(ax1);
set(gcf, 'ResizeFcn', @resize);
h = zoom(gcf); % <-- EDIT 2
set(h, 'ActionPostCallback', @resize); % <-- EDIT 2
function resize(varargin)
set(ax2, 'Position', get(ax1, 'Position'), ...
'YTick', get(ax1, 'YTick'), ...
'YLim', ylim(ax1));
end
end

AWSM work-around! :) Thanks so much.
However, I have one suggestion...
If you replace the line
uistack(ax1);
with
axes(ax1);
The user is able to still interact with the initial plot (i.e. use data cursor, etc)

Hey Oleg, I don't have the Stats toolbox so I can't try it out. But I have an idea. Make one figure with plotyy, then make another with the boxplot you want. Then either COPYOBJ the boxplot over to the plotyy figure or set the parent property of the boxplot to one of the plotyy axes. It might be worth a try...

Yes, but the problem is that I don't want the tick marks on the X axes, but I can't set Xtick, [] and keep the XtickLabels or TickLenght [0,0] and the tick marks on the Y axes!

Yeah, I noticed that. I would go with my solution above, because that uses boxplot as is. Even though the x labels are text objects, they do the "right thing" even when you zoom in and out.

also a bit of a workaround: make a plotyy where one the first dataset is empty or all zeros, then use 'hold on' to plot the boxplot over top.

Try this code please
% Create some sample data x = 1:10; y1 = rand(1, 10); y2 = rand(1, 10) * 100;
% Plot the first dataset figure; plot(x, y1, 'b-'); xlabel('X'); ylabel('Y1', 'Color', 'b');
% Add a second Y-axis yyaxis right;
% Plot the second dataset plot(x, y2, 'r-'); ylabel('Y2', 'Color', 'r');
% Set the color of the tick labels for the right Y-axis ax = gca; ax.YAxis(2).Color = 'r';
% Add a legend legend('Y1', 'Y2');
