whats a good ios charting library/framework

Question

Has anyone got any recommendations for a charting library/framework for ios. I need to be able to create bar, pie, line trend, scatter charts from an internal database/warehouse onto an iPad. I've read some mixed reports about core-plot.

Answer 1

iOS chart libraries

1.Core Plot : https://github.com/core-plot/core-plot

Core Plot is a plotting framework for OS X and iOS. It provides 2D visualisation of data, and is tightly integrated with Apple technologies like Core Animation, Core Data, and Cocoa Bindings.

Advantage: Core Plot is a free, open source charting library available under the New BSD License.

2.Shinobi Charts : http://www.shinobicontrols.com/ios/shinobicharts

Shinobi Controls released their new charting library, Shinobi Charts. This is a paid library but with a free 30 day trial available. It features several chart types, from Pie and Donut to Bar and Column and Area charts.Shinobi comes packaged with a comprehensive set of apple style documentation.

Advantage:

In terms of the smoothness of the interaction with the charts, Shinobi has a clear advantage. Pan and zoom have momentum and smoothly move to the new range requested. The performance of the Shinobi interaction is also markedly better than Core Plot, especially when there are a lot of labels visible on the chart.

Shinobi is very lightweight and perfect.

3.KeepEdge : http://www.keepedge.com/products/iphone_charting/

4.JBChartView : https://github.com/Jawbone/JBChartView

Jawbone's iOS-based charting library for both line and bar graphs. It is easy to set-up, and highly customizable.

Features :

1. Drop-in UIView subclass supported across all devices.
2. Lie and bar graph support.
3. Simple to use protocols modeled after a UITableView.
4. Highly customizable.
5. Expand & collapse animation support.

Disadvantage :

1. Requires iOS 7 or later.

2. Requires Automatic Reference Counting (ARC)

   After a bit of googling , i have found that Core-plot is one of most flexible libraries and free of cost . But if we can afford paid one ShinobiControls is worth of buying , it provides iOS software and Android components to ease the development of native, cross platform mobile apps.

Update
