I am creating a budget application in iPhone, to budget for personal incomes and expenses.
Client's need is
- I want to see line graph (like stock market line report).
- Red line for (monthly / weekly / daily) expenses
- Green line for (monthly / weekly / daily) incomes
The question is how? Till now, I have never faced this kind of requirement. Can you please some offer some guidance regarding creating line chart in iPhone?
You should try Core Plot.
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.
Step 3 ) Now open /Users/User-Name/core-plot/Examples
- You will find samples here.
