Plotyy - two x axes ticks not lining up correctly

Hi there,

I am using the plotyy function to plot two sets of data using 2 y axes and 2 x axes. For some reason the tick marks from the bottom x axis are "bleeding" on to the top x axis as you can see in this picture:

Any reason why this might be happening? Here is the code I'm using:

% Create figure
figure1 = figure('XVisual','','Color',[1 1 1]);

% Create difpercent vector
difpercent = (difinput./basinput).*100;

% plotyy graph
[AX,H1,H2] = plotyy(basinput,bas_hpa,difpercent,dif_hpa,@semilogx,@plot)

set(AX(1),'XColor',[0 0 0],'YColor',[0 0 0],'Parent',figure1,...
    'YTickLabel',{'200','400','600','800',''},...
    'YTick',[200 400 600 800 1000],...
    'YMinorTick','on',...
    'YDir','reverse',...
    'XMinorTick','off',...
    'XTickMode','auto',...
    'Position',[0.13 0.112403846153846 0.710158478605388 0.793461538461539],...
    'FontSize',16,...
    'FontName','Times');

axis auto;

set(H1,'Color',[0 0 0],'linewidth',2)

legend([,units,],'%','Location','Best')

% Create ylabel
ylabel('Pressure (hPa)','FontWeight','bold','FontSize',18,...
    'FontName','Times');

% Create xlabel
xlabel([,xaxistitle,],'FontWeight','bold','FontSize',18,...
    'FontName','Times');

% set properties for axis 2
set(AX(2),'XAxisLocation','top',...
           'YAxisLocation','right',...
           'YTick',[200 400 600 800 1000],...
           'YTickLabel',{'11.8','7.18','4.20','1.95',''},...
           'YMinorTick','on',...
           'XMinorTick','off',...
           'XTickMode','auto',...
           'YDir','reverse',...    
           'FontSize',16,...
           'FontName','Times',...    
           'Position',[0.13 0.112403846153846 0.710158478605388 0.793461538461539],...
           'Color','none',...
           'XColor','k','YColor','k');

% set Xlabel and Ylabel for axes 2
set(get(AX(2),'Ylabel'),'String','Altitude (km)','FontWeight','bold',...
     'FontSize',18,...
     'FontName','Times');        
set(get(AX(2),'Xlabel'),'String',[,x2axistitle,],'FontWeight','bold',...
     'FontSize',18,...
     'FontName','Times'); 

% set H2 plot line properties
set(H2,'Color',[0 0 0],'linewidth',2,'linestyle',':')       

% Set output size
set(gcf, 'units', 'pixels');
set(gcf, 'position', [200 150 650 550]);

THANK YOU!!!

Is there a difference between this and your still-active http://www.mathworks.com/matlabcentral/answers/17079-two-y-axes-not-lining-up-semilogx-for-one-line-for-the-other ?

[Aaron Burdick]

It's pretty much the same question. That one was related to Y axes and this one to X axes, but same issue.

Thanks.

No response to this? Is this simply a glitch in the program? Can Matlab not accurately do two Y axes and two X axes?
