Peter,

I would rather have a smalltalk solution than an activeX or third party
solution because a few years ago I evaluated Smalltalk Systems
WidgetKit/Business graphics for visualAge.

I had a terrible time with it.  after about two weeks I still could not
figure how to get their default labels off of my charts.  Plus, after
the evaluation expired, I could not even load my own code due to some
dependency issues.

In any case, last night I spent some time looking at ActiveX charting
packages and found a number of them with in the $300-$400 price range.
Unfortunately these seem to be licenses per developer machine.  (i keep
my code on a flash drive and work on diffrent machines depending on my
mood).

However, I did discover something pretty slick.  There were two products
which were based on Shockwave flash.  They sell you a .swf file and you
actually sent it xml to build the chart.  This is designed for use with
web applications.

One plus is that it is animated...you see the chart grow which is kind
of flashy (I assume this is optional).  Another plus is you don't have
to own the Flash MX development tool @ $499.   (or whatever tool you
would need.  they seem to have alot of different tools)


The Big question...

Does anyone know if/how to imbed a Shockwave activeX component into a
Dolphin Application?   (I have no experience with imbeding anything
activeX into Dolphin smalltalk.)

Finally two other things to investigate.  Microsoft MSChrt20.ocx seems
to come with visual studio which many people own...no need to buy
another.  Also, there is also a dolphin GDI++ library wrapper...which
someone here is working on...not sure if it alleviates any of these
problems...
