syms x y
fimplicit([x==0,y==0])
Apparently, the solution set for the second equation (y==0) is not plotted correctly. If x is understood by the function as the horizontal axis, which is suggested by seeing a vertical graph for the x==0 equation, the graph for the y==0 equation should be a horizontal line and it is not:
fimplicit(y==0)
Strangely enough, if the function definining the equation is only slightly perturbed, the problem dissapears
fimplicit(y+10e-8*x==0)
axis([-5 5 -5 5])

Hi, you could try the below code
fimplicit(@(x,y) x);hold on;fimplicit(@(x,y) y)
