Plot 2D is missing some Data Points

This is a strange situation for me. I have never seen this before.
I am just using a simple plot command for the following data:
x = [0.6935 0.6947 0.6959 0.697 0.6982 0.6994 0.7006 0.7017 0.7029 0.7041 0.7052 0.7064 0.7076 0.7088 0.7099 0.7111 0.7123];
f = [ 2.7433E+307 2.7042E+307 2.7477E+307 2.6278E+307 19.09965479 1.000000028 1 1 1 1 1 1 1.000000006 1 1 1 1];
p0 = plot(x, f, '-rx');
ylim([0 30]);
xlim([0.6935 0.7123]);
However the point at (x,f) = (0.6982, 19.1) is completely missing and the line does not pass through it. When I use Data cursor and use the keyboard arrows to move through the points on the line. This point shows up but there is not marker displayed for it.
This is really quite puzzling and would suggest some sort of a bug.
Any ideas? Please help.
I am using Matlab R2012b

I see same thing w/ default renderer of 'painters'
Changing to 'opengl' or 'zbuffer' changes behavior
Appears to be a computational problem owing to the magnitude of the values in the first of the data vector. If I even reduce the E307 to E300 the marker shows up.
