How I have all three error bars in one figure

R1=10
R2=27
R3=10
Rtotalseries=R1+R2+R3
Vs=5
Itotal=Vs./Rtotalseries
V1=(Vs./Rtotalseries).*R1
V2=(Vs./Rtotalseries).*R2
V3=(Vs./Rtotalseries).*R3
V1measured=1.058
V2measured=2.875
V3measured=1.063
V1percenterror=((abs(V1-V1measured)./V1))*100
V2percenterror=((abs(V2-V2measured)./V2))*100
V3percenterror=((abs(V3-V3measured)./V3))*100
errorbar(V1,V1measured,V1percenterror)
errorbar(V2,V2measured,V2percenterror)
errorbar(V3,V3measured,V3percenterror)

=> I'm trying to get all three error bar codes in a single plot figure

[Star Strider]

One opotion is to use the hold function (and also figure) —

R1=10

R1 = 10

R2=27

R2 = 27

R3=10

R3 = 10

Rtotalseries=R1+R2+R3

Rtotalseries = 47

Vs=5

Vs = 5

Itotal=Vs./Rtotalseries

Itotal = 0.1064

V1=(Vs./Rtotalseries).*R1

V1 = 1.0638

V2=(Vs./Rtotalseries).*R2

V2 = 2.8723

V3=(Vs./Rtotalseries).*R3

V3 = 1.0638

V1measured=1.058

V1measured = 1.0580

V2measured=2.875

V2measured = 2.8750

V3measured=1.063

V3measured = 1.0630

V1percenterror=((abs(V1-V1measured)./V1))*100

V1percenterror = 0.5480

V2percenterror=((abs(V2-V2measured)./V2))*100

V2percenterror = 0.0926

V3percenterror=((abs(V3-V3measured)./V3))*100

V3percenterror = 0.0780

figure
hold on
errorbar(V1,V1measured,V1percenterror)
errorbar(V2,V2measured,V2percenterror)
errorbar(V3,V3measured,V3percenterror)
hold off

Make appropriate changes to get the result you want.

Answer 2

[Walter Roberson]

R1=10

R1 = 10

R2=27

R2 = 27

R3=10

R3 = 10

Rtotalseries=R1+R2+R3

Rtotalseries = 47

Vs=5

Vs = 5

Itotal=Vs./Rtotalseries

Itotal = 0.1064

V1=(Vs./Rtotalseries).*R1

V1 = 1.0638

V2=(Vs./Rtotalseries).*R2

V2 = 2.8723

V3=(Vs./Rtotalseries).*R3

V3 = 1.0638

V1measured=1.058

V1measured = 1.0580

V2measured=2.875

V2measured = 2.8750

V3measured=1.063

V3measured = 1.0630

V1percenterror=((abs(V1-V1measured)./V1))*100

V1percenterror = 0.5480

V2percenterror=((abs(V2-V2measured)./V2))*100

V2percenterror = 0.0926

V3percenterror=((abs(V3-V3measured)./V3))*100

V3percenterror = 0.0780

errorbar(V1,V1measured,V1percenterror)
hold on
errorbar(V2,V2measured,V2percenterror)
errorbar(V3,V3measured,V3percenterror)
hold off

The third error bar is so close to the first error bar that it is easy to confuse them.
