iPhone data processing problems.

J2me previously often ask questions ...
Now learn the iPhone. They often come here.
Oh I hope you master wing;

A K-line I intend to do a Shanghai stock market's nearly 30 data
I've been here the level of received data open the
I like this definition.

const float high = {2701.04,2710.739,2753,2759.439,2790.919,2805.05,2804.209,2819.06,2835.409,2906.26,2934.469,2924.189,2939.28,2924.229,2932.82,2944.409,2868.479,2881.54,2890.32,2906.169,2931.58,2924.959,2937.56 , 2944.459,3000.429,3001.62,3012.044,2995.768,2966.98,2966.98};

Do not know the definition of an array has no problem.
Then how to convert these arrays can draw K line ...
Seeking ideas ...

opengl es dealt with this very convenient, but if you do such a stock system, then we need real-time updates interface, you need to update the performance is better, then opengl es is generated for this.
opengl es is a big topic, you go online to find some information to see it.

iphone support quartz 2d drawing, the same can achieve this functionality. An example of code,
- (Void) drawRect: (CGRect) rect {CGContextRef context = UIGraphicsGetCurrentContext (); CGContextSetStrokeColorWithColor (. Context, [UIColor redColor] CGColor); CGContextSetRGBFillColor (context, 0.0, 0.0, 1.0, 1.0); / / Draw them with a 2.0 stroke width so they are a bit more visible CGContextSetLineWidth (context, 2.0); for (int idx = 0; idx Reply:
About quartz 2d, you can take a look Stanford's CS193P class, this is the best material to learn the iphone programming,
