Want to plot a single point on an ezmesh plot

I have an ezmesh plot and I wish to add a single point that I have found previously. Here is what I have so far:
ezmeshc('x*sqrt(x.^2+y.^2)*besselj(1, 3.8316*sqrt(x.^2+y.^2))', [-1,1,-1,1])
hold on
plot3(mins(1,1), mins(1,2), -1*fval, 'ob', 'MarkerSize', 12)
The mesh will plot fine, but nothing comes up with the plot3 function. Where am I going wrong?

The ezmeshc function leaves the limits in manual mode. This means that if mins or fval are outside the limits, they won't be stretched to include the new point.
Other than that, I don't see anything wrong with this:
ezmeshc('x*sqrt(x.^2+y.^2)*besselj(1, 3.8316*sqrt(x.^2+y.^2))', [-1,1,-1,1])
hold on
plot3(0,0,.2,'ob','MarkerSize',12)
