Re: add default processing to _all_ charts.

[Software FX]

Eric, 

ICfxEvents is a PURE class. So you need to override ALL the functions, even 

if most of them do nothing at all. 

What I suggest is to copy the definition of ICfxEvents from the header file 

into your class and then replace all the PURE by { return S_OK; } 

Then only write code for those events you want to process.
