Instead of using core plot or an google api that needs an internet connection you can draw a graph yourself using quartz 2d. That's what I did for my app. CorePlot was kind of tricky to install and it seems complicated for small projects.

The advantage of drawing the graphs yourself is that you learn to use the standard drawing apis from Apple. Good luck

    I just recently implemented my own graphing library that I feel is pretty easy to use. Check it out. https://github.com/jsetting32/JSGraphKit – jsetting32 Mar 08 '15 at 00:54

The easiest way is to use google chart api, I use this in all my apps.

see the tutorial here,

http://code.google.com/apis/chart/image/docs/making_charts.html

you will directly get image as per your requirement just by making one HTTP Request.

  • then you should go to http://core-plot.googlecode.com/hg/documentation/html/iOS/index.html – HarshIT Feb 17 '12 at 07:30

    Why don't you try downloading core-plot, reading the documentation they provide, trying the examples and using search functions (google is your friend). You are going to have to do some of this.... – Nick Bull Feb 17 '12 at 10:02

If you want to draw graphs in iPhone applications using Objective-C or Swift, you can use SciChart, which supports over 20 popular chart types, including Column and Bar.

There are some really nice examples over at the scichart website for drawing chart types in Objective-C and Swift.

For instance:

Examples are also hosted on Github and there are also tutorials to help you learn this powerful tool.

enter image description here.

As a disclosure, i am the tech lead on the scichart project

I used Core Plot, it's easy to use and there are samples for almost all the graphs...

  • Core plot is good for small datasets, but it's really slow. There's a performance comparison here which compares against iOS-Charts, Coreplot, and two commercial charts for larger datasets, or frequent update: https://www.scichart.com/ios-chart-performance-comparison – Dr. Andrew Burnett-Thompson Jul 18 '17 at 20:20
