I WANT To fix my graphic to increase

i have 3 libe which i draw as like combine.

i am triying to make alll 3 lines start from same point and increase .

If you see the handwrite graph which i want to get is that.

and this graph what got output. how can i make it similar with hand writing graph

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')

Thank you for reply.😊 But i am wondering that here v_out must be upper than other 2line as like handwrite graph. How can i set it like handwriting one? 🥺 Thank you so much

[Dave B]

You mean, with changing the data?

y1=linspace(0,.5,100);
y2=sqrt(linspace(0,1,100))+.5;
y3=linspace(-1,1,100).^3;
plot(y1-y1(1),'g')
hold on
plot(y2-y2(1),'r')
plot(y3-y3(1),'b')
grid on
ylim([-.5 2])
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')

Definitely this! Thanks a lot☺

when i see it clearly v_out can not be like this its because v_act+v_ohm=v_out thats mean until up to the striped bar it should be go similar

[Dave B]

Yes I just picked some random functions that had a similar shape to what you showed: I think your choices are to either use the actual math that you'd expect to rpoduce these results or keep tweaking those functions to try to fake it?

[sevgul demir]

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.

[sevgul demir]

keeping tweaking those functions and get same may possible but i cant fixed it next time for other equation
