Ran in:
Could you just subtract the first value?
y1=linspace(0,.5,100);
y2=sqrt(linspace(0,1,100))+.5;
y3=linspace(-.5,.8,100).^3+2;
nexttile
plot(y1,'g')
hold on
plot(y2,'r')
plot(y3,'b')
grid on
nexttile
plot(y1-y1(1),'g')
hold on
plot(y2-y2(1),'r')
plot(y3-y3(1),'b')
grid on
ylim([-.5 1])
yline(0)
text(100,y1(end)-y1(1),"Vohm",'Color','g')
text(100,y2(end)-y2(1),"Vact",'Color','r')
text(100,y3(end)-y3(1),"Vout",'Color','b')

In fact, mathematically formulas exist in the codes, while 3 graphs are correct separately, but when I try to draw them together, it is not correct. Theoretically v_out=v_act+v_ohm . but the graph we have does not show this.
