MATLAB: How to give gap between curves? Please see the attached graph

Question

Hi,

I have generated the graph in which there are a lot of curves generated, but I do not want to plot all of the curves — there are 86 curves on that graph. I want to specify few curves only. I am not sure how to do it. Can anyone help?

Code:

w = [0,1,2,3,4,5,23,230,324,2130,2130,123,123,0.3242000,0.2320000,0.2232400000,0.271950151680000,0.307006225920000,0.344186910720000,0.383492206080000,0.424922112000000,0.468476628480000,0.514155755520000,0.561959493120000,0.611887841280000,0.663940800000000,0.718118369280000,0.774420549120000,0.832847339520000,0.893398740480000,0.956074752000000,1.02087537408000,1.08780060672000,1.15685044992000,1.22802490368000,1.30132396800000,1.37674764288000,1.45429592832000,1.53396882432000,1.61576633088000,1.231,1.78573517568000,1.87390651392000,1.96420246272000,2.05662302208000,2.15116819200000,2.24783797248000,2.34663236352000,2.44755136512000,2.55059497728000,2.65576320000000,2.76305603328000,2.87247347712000,2.98401553152000,3.09768219648000,3.21347347200000,3.33138935808000,3.45142985472000,3.57359496192000,3.69788467968000,3.82429900800000,3.95283794688000,4.08350149632000,4.21628965632000,4.35120242688000,4.48823980800000,4.62740179968000,4.76868840192000,4.91209961472000,5.05763543808000,5.20529587200000,5.35508091648000,5.50699057152000,5.66102483712000,5.81718371328000,5.97546720000000].'
%w = 0.00106230528000000
x = [0:0.008:3.4];
L = 3.4
E = 2.1E11
I = ((0.115465)^4)/12;
y = (((w.*x).*(L-x))/(24*E*I*L)).*(L^2+(x.*(L-x)))
plot (x,y,'Color',[0.4940, 0.1840, 0.5560],'LineStyle','-','LineWidth',1.5)

The x and w values cannot be changed. I want some sort of line saying that as plotting 1 to 86 graph…. plot 1,10,15 so on until curves on the graph

Answer 1

Do you want something like this?

plot (x,y,'Color',[0.4940, 0.1840, 0.5560],'LineStyle','-','LineWidth',1.5)
hold on
plot (x,1.86 * y,'b','LineStyle','-','LineWidth',1.0);
plot (x,1.10 * y,'b','LineStyle','-','LineWidth',1.0);
