I am Developing an Application which requires the following kind of the Thermometer. I am using the CorePlot.
Should I use the Core-plot or any other alternative or Any custom framework like this is already been developed?
I asked to use views because its easier and quick to implement. With core plot, It would be good if you go through documentation and understand how it works first.
"Vertical Bar Chart" in the Plot Gallery example app demonstrates this.
In your code, You need to set
CPBarPlot * barPlot = [CPBarPlot ...];
[barPlot setBarsAreHorizontal:YES];

I need to draw custom graph like those 3 images in iOS, can someone tell me how to accomplish this. Is it possible to draw those graph using core-plot open source library or i need to use quartz2d library explicitly.
There are some beautiful tutorial on how to draw custom graph in iOS.

You can use core-plot framework / XYPieChart for pie chart
I've created many types of interfaces using the Cocoa API — some of them using documented basic animation techniques and others simply by experimenting (such as placing an animated .gif inside an NSImage class) — which had somewhat catastrophic consequences. The question I have is what is the correct or the most effective way to create an animated and dynamic GUI so that it runs optimally and properly?
The closest example I can think of that would use a similar type of animation would be something one might see done in flash on any number of interactive websites or interfaces. I'm sure flash can be used in a Cocoa app, although if there is a way to achieve a similar result without re-inventing the wheel, or having to use 3rd party SDKs, I would love to get some input. Keep in mind I'm not just thinking of animation for games, iOS, etc. — I'm most interested in an animated GUI for Mac OS X, and making it 'flow' as one might interact in it.
If u wish to add many graphics animations, then go for OpenGLES based xcode project for iOS. That helps u to reduce performance problem. You can render each of the frames in gif as 2D texture.
I would recommend that you take a look at Core Animation. It is Apples framework for hardware accelerated animations for both OS X and iOS. It's built for making animated GUIs.
You can animate the property changes for things like position, opacity, color, transforms etc and also animate gradients with CAGradientLayer and animate non-rectagunal shapes using CAShapeLayer and a lot of other things.
A good resource to get you started is the Core Animation Programming Guide.
I have implemented crop functionality but
Is it possible to selection crop image like below link
http://deepliquid.com/projects/Jcrop/demos.php?demo=advanced
Short answer, not really unless you do some clever coding and view aligning / transforming.
Long answer, you have two options:
Create your own custom module with XCode, OBJ-C etc.
Just nest the Jcrop code in your own webview inside titanium. (This seems easiest).
I'm trying to use a scatter plot from Core Plot in my iOS application. I set up Core Plot as the Core Plot wiki says, and then I copy PlotItem.h/m, PlotGallery.h/m and SimpleScatterPlot.h/m from the included Plot Gallery project into my project. The code
CPTTheme *theme = [CPTTheme themeNamed:kCPTDarkGradientTheme];
SimpleScatterPlot *scatterPlot = [[SimpleScatterPlot alloc]init];
[scatterPlot generateData];
[scatterPlot renderInLayer:hostView withTheme:theme];
runs, and the graph view is shown in my app. But I cannot move the graph view around or tap the plot points as in the Plot Gallery project. How do I set this up right?
The Plot Gallery is a poor starting point for a simple Core Plot demonstration. It has a lot of extra "stuff" to support generating a table view with thumbnails of all the different plots. The -renderInView:withTheme: method is used to make the thumbnail images for the table view. It renders the graph as an image which is why you lose interactivity. Unless you need the flexibility to quickly add new plots to your app and easily support both MacOS and iOS, I would recommend using one of the other examples as a starting point. The architecture is much simpler and easier to understand.
You need to have a CPTGraphHostingView in the visible view hierarchy. Set your graph as its hostedGraph. Look at any of the other example apps to see how to set up the hosting view. The graph setup and datasource code in the Plot Gallery plots (e.g., SimpleScatterPlot) is fine and should work anywhere.
In my application I have to read data from a file or core data and draw a bar graph using that data. Can any one help me in drawing the bar graph in a simple way?
I have used the Core Plot library successfully. Here are some basic tutorials, but you will have to adjust to suit your particular scenario:
