You bring up a couple of interesting ideas.

To answer one, could you not use transparency of one plot to bleed through one underneath?

I also wonder if textplot could also be used here.  Let's say using sin(x) 

with(plots):
a:=plot(sin(x),x=0..3,color=green):
b:=textplot([3.5,.1,"sin(x)"],color=green):
c:=plot(0.1,x=3..3.2,color=green):
display(a,b,c,view=[0..4,default])

Of course positioning was all manual.

Discrepency has been resolved.  The value that is downloaded here by the FOREX application is the average ASK price for the day, not the closing value as I thought.  This is how Onada delivers the values. 

It would also be nice if it could be modified to pick up closing values.  Most likely, however, have to find a new website for the data.

Using Maple to figure out a way for financial gain always proves useful.  At least in theory. 

Interesting question, I enjoy the financial problems you come up with.  I can't think of anything at the moment.  But regarding your thought that one would think PW+PL-200 = 0, whenever percentages are involved in the calculation equating the negative and positve absolute changes in values equally isn't always true ... as I think you already know. 

Well I did have something of an idea, and it could be minutely related so suppose someone is laid off, he can collect EI but only for a certain period of time.  And that length of time is related to the unemployment rate in your local region (a quick example, currently Hamilton unemployment rate is 6.9% entitling you to a maximum of 38 weeks of EI and Toronto unemployment rate is 8.1% entitling you to a maximum of 42 weeks - I suppose that's analysis for another time)... regardless ... when that period has ended and you are starting fresh, supposing you found work (in this economy today, it is supposing times ) Referring to a chart again based on local unemployment rates you have to work a predetermined number of hours before you can re-apply for EI.  (In our little example Hamilton = 665 hours and for Toronto = 595 hours)

Not sure that it's fair since EI payments are based on where you work and not where you live, two people working in the same company and living in different cities collect totally different EI rates.  None-the-less... hmm perhaps a Maple worksheet is in order here (on a quick thought use the sockets package to grab data from the government of canada website and find out the worst possible place to work for EI benefits if you live in a different city ... just a thought)

My point to loosely relate it to your question is that, well I suppose it's not really related.  But if unemployment rates are above 6% what's the probabiltiy of loosing your job again before you've reached your predetermined number of hours required for EI benefits?  I suppose that could be considered winning your EI benefits, no?

Today September 23,2011 from Oenda.com FOREX proc has the CAD to USD exchange at .98050 where the Bank of Canada and the radio reports the CAD dollar at .9714.  What exchange rate are they using?

I'm not sure if this is deliberate or not but if add comment to a question is posted it will not move to the top and be recorded as the most recently replied thread.

Ok, cleared up.  I thought there was a version 1 and 2 for Maple 13 and a new vesion 15 (total of 3 differnet versions) when in fact the reference to version 2 was the Maple 15 version. 

I was expecting and trying to get the Maple 13 version working (since obviously closer to Maple 12 I would think the version for Maple 15 would have even more errors.  My bad.  The Maple 15 version with the string manipulation adjusted works in maple 12. 

The component Button0 errors were a result of a string manipulation problem which was fixed in the Maple15 version.

You mean like in Word where you can set up your page, see the margins and see exactly where words will end up on the printed page? 

It seems to me if Maplesoft hired a few extra programmers to take on small bug programming tasks, that would then allow the advanced programmers to take care of more advanced problematic and annoyance issues on top of implementing and adding new functionality. 

Also here in mapleprimes, ideas seem to get gobbled up in the void as if the ideas were presented here as a primary source then forgotten about.  Might I suggest to Maplesoft that a speakers corner be implemented (in my old company a representative from all teams would meet, write issues on a flip chart and assign names to people who were tackling the task).  This gives a sense of visibility to all the problems at hand and a sense of urgency to the people who's names are assigned tasks not yet completed.  I'm sure they have something similar like team meetings but speakers corner attacks problems from a different angle. 

I'm sure the developers have a lot on their plates.  It's possible there were more serious issues that trumped the 3d plotting algorithm from being changed for Maple 12.  DJ Clayworth did mention "if it were to be changed" meaning that it sounded like it wasn't on anyones plate right then.

Hmm, yes my suspicion is you may have added something to Maples install lib folder and fogot about it (hence your question to why imaginaryunit is j and not the default I.

From here http://www.mapleprimes.com/questions/124341-Step-By-Step-Guide-For-Creating-A-Standalone and I quote from Acer "It's really not a good idea to stick new files into your Maple installation's "lib" folder. You or someone else will end up forgetting all that you've added, some day. Better is to add it to another folder altogether, and then augment `libname` in worksheets intended to use it (eg. in Startup code, if you want that hidden from view)."

And some good advice about using it in Startup code where you have logically gone looking for it.  By deduction it can only exist in some other ini file, or in a lib file.  I think those are the only two places left to look. 

The next unconventional, less desireable technique would be to re-install your Maple 13.

@ Ratch, anything in the startup code would be there as you explained, it is not hiding on you. 

And if it works on restart and nothing is in the startup code region then the command inteface(imaginaryunit=j) must be in the maple.ini file
