Matlab橫坐標從特定值開始

set(gca,'XTick',1:1:length(x));
set(gca,'XTickLabel',{'15','20','25','30','35','40','45','50','55','60','65','70','75','80','85','90'...
     ,'95','100','105','110','115','120','125','130','135','140','145','150'...,
     '155','160','165','170','175','180','185','190','195','200'});

　　如上圖，左側區域有空白，我設置XTick和XTiclLabel還是不行，后來xlim(15,200),提示參數不夠，那么xlim([15 200])就可以了;
