iOS how can I make MapKit display custom indoor map?

I'm trying to create a map of the office I'm working at. I have a high resolution image, and would like to autorotate it in the direction the user is heading, allowing the user to navigate around the map. I thought this could be accomplished using CoreMotion/CoreLocation and a UIScrollView, but this seems like there's some work involved.
So I'm wondering if there are easier solutions for combining a custom map and direction/position on that map - can MapKit handle this for me? Are there other frameworks that can help me show a local 2D map with compass orientation on it?
You can convert your high-res image into map tiles easily with TileMill.
You should use some custom tiles with MKTileOverlay which only display at a very high zoom level (like z 18 or whatever). I suggest you take a look over at NSHipster and read what they have about it:

*Disclaimer: I haven't tried this myself, came across the NSHipster article while searching for solutions to my own problems.

Drawing a custom bar chart graph in iOS(PowerPlot vs Core plot)

I have been looking all around the net for open source graph plot framework for iOS, but I am struggling with it as of now. I have worked on an app and used PowerPlot Graph Plot framework http://powerplot.nua-schroers.de/examples/webtraffic.html
I am trying to draw a bar graph chart showing two years at once without stacking each, like in the image below: As you can see there is a problem of resizeing and the scaling isnt uniform. I would like to make the chart look bigger and the y axis be more formatted.
Any suggestions because I always hear about core plot also by which you can achieve such(see below), but all i hear about coreplot is flexibility and customization issues.
You can easily produce a bar plot like that with Core Plot. Give it a try and ask specific questions here on StackOverflow if you get stuck.

What graphics library with custom controls should be selected for ios development?

I want to find a graphics library for iOS (specifically for iPad), which will have the following features:
Map
TreeMap
Charts (and their asynchronous rendering)
Time navigator
Grids
Drill-Down
Multiaxial
Crosshair
Manual drawing
Zoom
Ability to draw shapes or polygons
Different types of charts (piechart, areachart, barchart, ...)
At the moment I came across a Shinobicontrols. Can be experienced developers prompt me which of the following is in the library, and what is not. And may prompt other libraries.
You might want to look at cocoa controls.

iOS: draw editable Graphs in iPad App, using html5

In my App I need to draw graph data with different datamodels that frequently change and can not be generalized. This graph data must be editable with a slider or a segmented control.
The idea is to load all necessary data to draw the graph from the server. Is html5 the right solution? Can the iPad-UI-Controlls used to manipulate the graph?
Where do I start and how much work is it?
Currently I'm using Core Plot to draw the graph - but I need to model my graph data on the server.
Option 1: If you are developing for Android as well or you are better at javascript, then you can use HTML5.0. Have a look at http://www.sencha.com/products/touch/charts/
Option 2: If you want to develop it natively for iPad(which I feel is a better option), then please look at google library for graph http://code.google.com/p/core-plot/ and Is there a good charting library for iPhone?
I extended the work of this gentleman:
http://buildmobile.com/creating-a-graph-with-quartz-2d/#fbid=EKAB22zV7It
And I'm quite pleased with the results. It took me about a week to get my graph able to draw a stock chart with scrolling, pinching zooming, 3 different symbol indicators, a secondary plot line, tap-able data points with a little custom popover showing details, and a few annotations. Not bad considering the overall complexity, and largely thanks to the detailed walkthrough.
He also talks about why he didn't use Core Plot.
Good luck,
Damien

Chart component for Monotouch?

For my client I have to develop a dashboard for the iPad (in Monotouch), showing several charts. Is there a chart component available for MonoTouch? Or does anybody have an idea to generate charts for the iPad?
Thanks,
Danny
There are a couple of commercially available chart components with MonoTouch bindings:
ShinobiControls - have launched a beta of their bindings
Steema Charts - have MonoTouch bindings
I was looking for such a control for charting but haven't found one. I draw my graphs manually. After all it is not so big deal just a bit of math. I draw pies and bar graphs.
