remove points in a figure that are close to 0 vertical line

Say I have:

X = [0 0.5 0.12 0.54 0.21 0.21 0.12 0.32 37 30 39 50 42]'
Y = [134 423 352 212 545 234 184 563 323 123 485 182 493]'
plot(X,Y,'g')

I want to remove points that are less than 'n' from the plot for X

Say n = 20, so points that are less than 20 in matrix X will be removed from the plot.

hi

as simple as this :

X = [0 0.5 0.12 0.54 0.21 0.21 0.12 0.32 37 30 39 50 42]'
Y = [134 423 352 212 545 234 184 563 323 123 485 182 493]'

n = 20;
ind=find(X>n);
plot(X(ind),Y(ind),'g')
