Charting API?
-
I want to add some simple bar graphs and pie charts to my project. Is
there an apple api for charting or do you need to use a 3rd party
product?
Thanks In Advance -

Apple's framework is private. I've been toying with SM2DGraphView,
it's pretty nice:

Google Offers an Chart API, you could include it with Webkit.
But i think thats not that what you searched.

There's also Narrative: https://sourceforge.net/projects/narrative/
I don't know if it's any good but it's Cocoa.

I've been using Chartdirector:
http://www.advsofteng.com/
Not Cocoa, but easily usable and very powerful.

Dix, thanks so much for the tip - I had never heard of this package
before (the company appears to be located in Hong Kong. I just looked
at their web site, and it would appear they have a nice suite of
graphs.
What I glean from the web site is as follows:
- for MacOS X, they deliver a universal library and header files
- the library is C++ (I would imagine it would integrate into a cocoa
app fairly well)
- single user price is $99 (much more than the DataGraph library that is $29)
- redistribution license is $749. This is the only library I have
found that offers redistribution.)
All in all looks very promising.

One other library worth keeping an eye on is QWT
(http://qwt.sourceforge.net/). It's a very impressive 2D and 3D
plotting library for Trolltech's qt. There is a qt for mac, but it's
Carbon based so I don't think it's practical to use QWT with Cocoa,
but Trolltech is investigating migrating Qt-Mac to Cocoa (because of
the lack of 64-bit support in Carbon) at which point, QWT would become
pretty awesome.

Regarding the Google Charting API that was mentioned, you can take
simpler route and avoid the need to embed a WebView by just querying
for a chart and loading the result into an NSImage.
The idea comes from Philippe Mougin, and can be viewed at: <http://pmougin.wordpress.com/2007/12/10/google-chart-api-fun-with-cocoa-and
-f-script/>. He focuses on using F-Script to accomplish the task, but it's
very easy to see the general Cocoa approach.

hi-
You can use Vvidget Code (http://www.vvi.com/products/vvidgetcode)
which now has an IB 3.0 palette and a four-way framework for Leopard
(http://www.vvi.com/news/2008/0215vvidget.html) .
thanks!-

I'll add my recommendation for SM2DGraphView as well. The docs are
good and the code works well.

When I looked into this last fall I decided I liked the look of
DataGraph and bought a license, but then I ran into trouble
incorporating it into a garbage-collected app and started writing my
own. Mind you, that could have been me and my Fortran IV - imprinted
brain, but now I too am reevaluating the situation. GC is no longer
relevant as I'm using core video buffers, but now I'm worried about
the long-term viability of all the libraries mentioned (DataGraph,
SM2DGraphView, Vvidget, Google Chart, Narrative etc.). I'm inclined
to go with SM2DGraphView as the source code is available and
understandable.

I strongly urge everyone who's interested to file an Apple bug report
asking that they make their framework public, as it (apparently)
produces some of the most beautiful graphs around. Beauty is *almost*
the most important point here...

As the developer of DataGraph, I am definitely planning on continuing
to support the framework for a long time. I try to be very responsive
regarding any problems with the framework, and I have a bulletin board -
http://www.visualdatatools.com/phpBB2/ where issues can be brought to
my attention. I'm curious to know if what could be wrong with GC and
the DataGraph framework.
DataGraph grew out of DataTank. I have worked on DataTank for a long
time, so should have built up some trust regarding staying power. I
keep up with current versions/updates to the system. Sometimes this
is surprisingly messy, for example because of changes in NSTableView
and NSTokenField in 10.5. I don't yet have a 64 bit version as part
of the release, but I've gone through the code and it is 64 bit
clean. I can do a 64 bit version (quad binary) if there is interest.

My graph style tends to be "Tufte" like, with emphasis on publication
quality graphs, but allow gradients, etc if you want to do flash. The
framework is paired with the application, and one way to think of it
is that the application works as a "interface builder" and a way to
test your work during debugging. I don't know exactly what the
GraphKit API looks like, or which Apple applications actually use it.
The graphs don't quite look consistent between KeyNote, Shark, XRay
and Activity monitor.

KeyNote uses its on classes, Shark, Chud, Activity monitor and I
believe XRay use GraphKit.
