Answer 1

I've done graphing using some javascript based graphing libraries but this project looks quite good to me I'd have look at this as an option s7graphview

Answer 2

You should try Core Plot.

Answer 3

I think this is the solution for it.

If you want to use graphs in your application, there are two options for you.

* Core Plot - http://code.google.com/p/core-plot/
* s7GraphView - http://code.google.com/p/s7graphview/

I found that s7graphview is more preferable to iPhone application & Core-Plot is more suitable to MAC OSx development.

I have downloaded both of them & started R & D on implementing it on application.

But Core-plot provides different kinds of facility & advance features while s7graphview is very limited.

Let me explain, how to install core plot,

First Go to this site,

http://code.google.com/p/core-plot/

You will see a command there(as given below) but you will not be able to execute it in your mac os terminal.

( hg clone https://core-plot.googlecode.com/hg/ core-plot )

Because it requires following things

• Mercurial
• Terminal Settings

Step 1 ) Let me explain terminal settings. Open Terminal & execute following commands

• export LC_ALL=en_US.UTF-8
• export LANG=en_US.UTF-8

Step 2 ) Download & setup mercurial from following link.

• http://mercurial.berkwood.com/

Step 3 ) Now open /Users/User-Name/core-plot/Examples

• You will find samples here.
