Here achieved several function curves gathered together, as long as the data input into the program, you can directly out of the overlay of the image. This is the last class, and there are other steps you can follow online.
x=0:2:10;
xlim([0.10]); % limit x coordinate value range ylim([0.120]); % limits the range of y-coordinate valuesset(gca,'xtick'.0:6:10); %gca is the handle to the current axis, and xtick indicates where I want to set the X-axis scale to displayset(gca,'xticklabel', {0.2.4.6.8.10}); % xtickLabel represents what is displayed on the setting scale, followed by the actual value % that you want to displayset(gca,'xtick'[0 2 4 6 8 10]);
%set(gca,'xticklabel', {'0'.'2'.'4'.'6'.'8'.'10'});
y=[0 10 20 30 40 50 60 70 80 90 100 110 120];
