showing the distance between the two plots on two curves at regular intervals on the same plot

11 vues (au cours des 30 derniers jours)
for example two lines are plotted with equation line 1 x=t^2 and y=(0.5*(t^2))// path and line 2 y=2x+6 // which is boundary i want them within the boundary so discared other points
i want two display the distance between two lines at regular intervals on the same plot indicating the distance between them
t=0:0.2:10;
for k=1:length(t)
x(k)=t(k).^2;
y(k)=0.5*(t(k).^2)+10;
m(k)=(2*x(k))+6;
end
c=y<=m
l=y(c);
g=x(c);
plot(g,l)
hold
plot(x,m)
legend('path','boundary')
xlabel('x-axis')
ylabel('y-axis')

t=0:0.2:10;
% avoid loops wherenever possible, use element-wise operations instead
x=t.^2;
y=0.5*x+10; % the same as "y=0.5*t.^2+10;" but faster
m=2*x+6;
%
c=find(y<=m);
plot(x(c),y(c),'.-b',x(c),m(c),'*--r');
legend('path','boundary')
xlabel('x-axis')
ylabel('y-axis')

Try the datatips:
t=0:0.2:10;
% avoid loops wherever possible, use element-wise operations instead
x=t.^2;
y=0.5*x+10; % the same as y=0.5*t.^2+10; but faster
m=2*x+6;
c=find(y<=m);
plot(x(c),y(c),'o-b',x(c),m(c),'*--r');
legend('path','boundary')
xlabel('x-axis')
ylabel('y-axis')
%
n=5; % add a datatip to every 5th point
hold on;
cp = plot(x(c),m(c)-y(c),'LineStyle','none');
for k=1:floor(numel(c)/n)
datatip(cp,'DataIndex',k*n+1,'FontSize',8);
end
hold off;

i want to indicate the distances between the curves/lines at some regular interval say at 10,20,30.. on x-axis within the same graph is there any plotting technique to show them other gtext and inserting arrow at those points

i used find so that i wanted the points which confined between the boundary line , x-axis and y-axis @madhan ravi
