how to omit zero values while plotting the graph

could anyone tell me how to omit zero values while plotting the graph.

A)

yplot=y;              % make a copy of the data specifically for plotting
yplot(yplot==0)=nan;  % replace 0 elements with NaN
plot(x,yplot)

will return broken lines between locations which contain zero in yplot

B)

isNZ=(~y==0);           % addressing logical array of nonzero elements
plot(x(isNZ),y(isNZ))   % plot only the subset

will be solid line just without those points that were zero

Many thanks. I was struggling with something like this but this code helped me too much
