You want to add pod 'Chartreuse', '~> 0.0' similar to the following to your Podfile:

target 'MyApp' do
  pod 'Chartreuse', '~> 0.0'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try Chartreuse

Chartreuse 0.0.1

Lightweight, stylish charts for iOS!

NOTE: Currently only supports pie-charts, but requests are welcome!

Contains source and a fully working universal app project.

(I'd also check out core-plot to make sure it isn't what you want, first; chartreuse is very light-weight.)

Using is easy as pie...

Basically, grab the two main files (PieChartView.[h|m]) from PieChartViewExample/Classes/ and add them to your project (or create a submodule or whatever). Then:

// Set a gradient to start 1/3 from the top, and continue to the bottom
[_pieChart setGradientFillStart:0.3 andEnd:1.0];
// Use black 0.7 opaque for our gradient
[_pieChart setGradientFillColor:PieChartItemColorMake(0.0, 0.0, 0.0, 0.7)];

// Create three data items to show in our pie chart
[_pieChart addItemValue:0.4 withColor:PieChartItemColorMake(1.0, 0.5, 1.0, 0.8)];
[_pieChart addItemValue:0.3 withColor:PieChartItemColorMake(0.5, 1.0, 0.5, 0.8)];
[_pieChart addItemValue:0.3 withColor:PieChartItemColorMake(0.5, 0.5, 1.0, 0.8)];

// If the piechart is hidden, show it
[_pieChart setHidden:NO];

// Force the drawRect: method to be called
[_pieChart setNeedsDisplay];

Or if you want to fade the pie chart in, you can do:

_pieChart.alpha = 0.0;
[_pieChart setHidden:NO];
[_pieChart setNeedsDisplay];

// Animate the fade-in
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
_pieChart.alpha = 1.0;
[UIView commitAnimations];
