Hello,

I had the same problem. I looked a lot on the internet but couldn't
find anything.
Here is how I manage to overcome this problem:

Epilog -> {If[ x > xMin,  PointSize[.02], { }],  Orange, Point[ptX]},

Basically you return an empty option by using '{}' when the condition
is false.

I hope this helps.
Panayiotis.
