tl;dr:

Use , roll your own CoreGraphics implementation, or use a WebView with a JavaScript plotting library, such as Highcharts or FusionCharts

I needed to chart some data for an iPad app. Here’s some options I’ve found in my research:

I looked on StackOverflow but there was no clear winner: http://stackoverflow.com/questions/7254882/line-graphs-on-ios

Some suggest writing your own with CoreGraphics; some mention ShinobiControls (see screenshot above), which costs like $1,000 and that was a deterrent for me trying it. EDIT: They do seem on top of their customer support though. ;) http://www.shinobicontrols.com/shinobicharts/price-plans/

Core Plot

This is what most people suggest. It does apparently anything you want. But it’s on Google Code and the documentation is awful.

Sencha

If you’re not doing native work, I should mention Sencha has some pretty nice looking stuff: http://dev.sencha.com/deploy/touch-charts-1.0.0/examples/

However, I am only building native apps, so it doesn’t help me that much.

Lameness

Then there’s tons of lame sites last updated in 2010 that you should stay away from: http://www.keepedge.com/products/iphone_charting/ http://www.iphonechart.com/company/

JavaScript

I ended up using a JavaScript framework instead and build a WebView locally using that library. It’s worked out pretty well:

I used FusionCharts, but I’ve also used Highcharts before and liked it even more. However, FusionCharts has a nice tutorial for how to embed it inside an iOS app.

Or you could use .

That ended up working great for the quick nice chart I needed. Hope this helps you. If you’ve used other tools, please let me know by commenting below.
