FX chronograph questions

I started with a Caldwell Chronograph and then graduated to ths FX chrono. One of the things I miss with the FX is the ability to edit the shot strings. With the Caldwell I could delete individual shots in a string and the software would recalculate the average, extreme spread, and the standard deviation. Is there a way to make the FX software make the same adjustments?

Also is there a way to print out the shot string graph?
 
This is good information to know for IOS. Have been using FX Radar for almost two years and never knew about this little gem! 

Q. I can guess as to some “reasons” why you might delete a shot, but can you guys enlighten me as to why/when you delete a shot(s)? I realize you can always improve your ES spread by removing a bad shot ( or a shot that has a big FPS variance). Why specifically do you remove shots?

Thanks
