[RELEASE] iPlot : Function grapher

[Mantu]

iPlot, function grapher. V.0.60

New version 0.60 available now at bigbosses reposity!
What changed:
- Major fix: Functions and settings are now saved with newer firmwares also. (it worked previously only on 1.1.2).
- Possible crashing bug when zooming too far or near fixed. Also limits no longer reset when zoomed too much, instead zooming is just halted.
- And also some parser improvements.

Version 0.52 changes:

IPlot is now available at bigbosses reposity!

Program doesn't work with firmware 1.1.1!

Info:
Program draws mathematical functions. It can find roots, minium, maxium and integrals of functions. You can also draw derivate of functions. You can add up to 20 functions to graph. IPlot has a lot of different elementary functions. For example: sin(x), ln(x) also some rare ones: csc(x)... You can do all the necessary graph manipulations: pan, zoom in and out, zoom to defined region and set graph limits by hand.
See more about features in help section of program.

I hope you find program useful. It has potential to partly replace big and clumsy graphing calculators. But remember it's only grapher and not calculator.

Program is coded in objective-c so you don't need any fancy runtimes.

Install it via ssh to your ipod touch (or iphone). Also remember to set permissions (0755). I hope program could be hosted at reposity. So it would be easier to install through installer.

I have only tested iPlot on my ipod touch with firmware 1.1.2. I hope people would test this program and tell me how it works. Let me know if you find any bugs.

How to exit plot view:
Double click the graph and it goes back to main menu.
Read help section of program!

How to delete functions:
Swipe over function on function list.

Todo:
- Figure out why program doesn't work with firmware 1.1.1
- More improvemts to UI
- Add more graph style options
- Polar coordinates
- Parametric functions
- Multitouch zoom
- Hmm something else...

Credits:
Everything else by me (Mantu), but credits of function parser (component that tells to device how to calculate given function) goes to http://warp.povusers.org/FunctionParser/.

Gonna test now. Looks amazing.
+ REP

[Mantu]

Thanks (it's nice to be worshipped).

Thanks man, I have something similar for phone(java), but this is much better. Good job.
Also it would be cool to integrate some good calculator and this app(MACalc).

Nice work...

dl'ing now...

[Mantu]

Hope it works out with everyone. Could someone tell me how I can put this to reposity for example to ipod touch fans reposity?

[jmiz9000]

mantu can i put this on my source?

[Mantu]

Did you test it already?
I think it would be better to wait a little than straight away push it to reposity. In case of someone now finds some terrible bug.
But yeah sure you can host it, but I recommend we wait that few people test it first.
