How to change number of ticks, tick position, and value on plot?

I have a bar3 plot but the axis values and positioning of ticks are wrong. I want the axis, ticks, and tick values to look as such in the figure without the data. But when I plot my data, the axis looks like this instead. Can someone please tell me what I am doing wrong? Thank you in advance. This is the code that I have.

h = bar3(cell2mat(hrPax)); 

 set(gca,'XTickLabel',[103.6 103.7 103.8 103.9 104]);
 set(gca,'YTickLabel',[1.5 1.45 1.4 1.35 1.3 1.25]);

 axis tight;

 for kk = 1:numel(h)
  h(kk).CData = h(kk).ZData;
  h(kk).FaceColor = 'interp';
end

Set the tick values and the limits, not tick labels. Tick labels just write the label values on the tick marks that have been otherwise set by the auto-scaling routines; they have nothing to do with how many or what the actual values are.

set(gca,'XLim',[103.6 104],'XTick',[103.6:0.10:104])
set(gca,'XLim',[1.25 1.50],'YTick',[1.25:0.05:1.50])

NB:

You don't show actual data; you've written the 'yticklabel' in descending order; that may not be the same as the ticks themselves unless you've previously done

set(gca,'ydir','reverse')
