What are the alternatives to Core-Plot for drawing graphs in iPhone SDK

Question

Are there any alternatives to Core-Plot for drawing graphs in iPhone SDK?

I am having hard time integrating core-plot in my app. Lot of issues.

Can you please suggest some alternatives to core-plot?

Some of the alternatives that I found were:

These links do not work. They are already down:

I hope this helps.

If what you intend to draw is relatively easy, you may get quick results by using Quartz and drawing the graph yourself. Just subclass an UIView and override its drawRect: method.

A very, very simple example of drawing a square, 10x50 pixels at a fixed position, via Quartz:

- (void) drawRect:(CGRect)rect
{
    CGContextRef ctx = UIGraphicsGetCurrentContext();
    CGColorRef red = [[UIColor redColor] CGColor];

    CGRect barRect = CGRectMake(10.f, 20.f, 10.f, 50.f);
    CGContextSetFillColorWithColor(ctx, red);
    CGContextFillRect(ctx, barRect);
}

Since the OP asked his questions, there has been an abundance of new chart libraries. GraphKit, TWRCharts, to name only two. CocoaControls lists a lot more, if you do a search for 'graph'. So I'd like to gather more feedback with regards to this question.

iOSPlot, iOS:Chart, KeepEdge Library, Shinobi Controls
