plot - Multiple y axes in MATLAB (axis alignment issue when printing) -

here sample of strange problem. i'd plot curves multiple y axes , use common method in matlab.

function plot_test()  clear;  savefile = 1;  scrsz = get(0,'screensize'); figure('position',[1 1 0.9 * scrsz(3) 0.9 * scrsz(4)]);  hold on; box on;  x = 0:1:10;  h1 = plot(x, x.^2 , 'r', 'linewidth', 2.5);  %axis label xlabel('xlabel', 'fontsize', 20, 'interpreter', 'latex'); ylabel('ylabel', 'fontsize', 20, 'interpreter', 'latex'); set(gca, 'fontsize', 20, 'linewidth', 3);  ax1 = gca; ax2 = axes('position',get(ax1,'position'),'xaxislocation','top','yaxislocation','right','color','none','xcolor','none','ycolor','k'); linkaxes([ax1 ax2],'x'); hold on box on; h2 = plot(x, x, 'b', 'parent', ax2, 'linewidth', 2.5); ylabel('second ylabel', 'fontsize', 20, 'interpreter', 'latex'); set(gca, 'fontsize', 20, 'linewidth', 3);  hl=legend([h1 h2],{'first line','second line'}); set(hl,'fontsize',15,'location','northwest', 'orientation','vertical')   %save pdf if savefile     % backup previous settings     prepapertype = get(gcf,'papertype');     prepaperunits = get(gcf,'paperunits');     preunits = get(gcf,'units');     prepaperposition = get(gcf,'paperposition');     prepapersize = get(gcf,'papersize');      % make changing paper type possible     set(gcf,'papertype','<custom>');      % set units same     set(gcf,'paperunits','inches');     set(gcf,'units','inches');       % save pdf     print -dpdf test.pdf;      % restore previous settings     set(gcf,'papertype',prepapertype);     set(gcf,'paperunits',prepaperunits);     set(gcf,'units',preunits);     set(gcf,'paperposition',prepaperposition);     set(gcf,'papersize',prepapersize);     end 

the objective print pdf of figure , save in same folder test.pdf. accomplished axes misaligned. on windows machine looks horrible while on mac looks okay (but if closely, y-axes indeed misaligned @ bottom).

this happens when use second axis. without that, runs perfectly. idea why?

okay, found way: trick use plotyy. sample code below

function plot_test2()  clear;  savefile = 1;  scrsz = get(0,'screensize'); figure('position',[1 1 0.9 * scrsz(3) 0.9 * scrsz(4)]);  hold on; box on;  x=(0:1:10); y1=x; y2=x.^2; [hax, hline1, hline2] = plotyy(x,y1,x,y2);   %axis label xlabel(hax(1),'xlabel', 'fontsize', 20, 'interpreter', 'latex', 'color', 'k'); ylabel(hax(1),'ylabel', 'fontsize', 20, 'interpreter', 'latex', 'color', 'k'); ylabel(hax(2),'second ylabel', 'fontsize', 20, 'interpreter', 'latex');  set(hax,{'ycolor'},{'k';'k'}) set(hax,{'fontsize'},{20;20}, {'linewidth'}, {3;3}) set(hline1,'linewidth', 3) set(hline2,'linewidth', 3) set(hline1,'color', 'r') set(hline2,'color', 'b')  hl=legend([hline1 hline2],{'first line','second line'}); set(hl,'fontsize',15,'location','northwest', 'orientation','vertical')   %save pdf if savefile     % backup previous settings     prepapertype = get(gcf,'papertype');     prepaperunits = get(gcf,'paperunits');     preunits = get(gcf,'units');     prepaperposition = get(gcf,'paperposition');     prepapersize = get(gcf,'papersize');      % make changing paper type possible     set(gcf,'papertype','<custom>');      % set units same     set(gcf,'paperunits','inches');     set(gcf,'units','inches');      % save pdf     print -dpdf test.pdf;      % restore previous settings     set(gcf,'papertype',prepapertype);     set(gcf,'paperunits',prepaperunits);     set(gcf,'units',preunits);     set(gcf,'paperposition',prepaperposition);     set(gcf,'papersize',prepapersize);     end
