I have a need to render and display charts (bar charts for now, but more types may be needed later) in an iPhone app I'm working on. I've done some looking around and it doesn't look like there are any really good, mature charting libraries for iPhone yet. I've also looked for something written for Cocoa on the Mac that can be adapted, but haven't found anything great yet.
Anybody dealt with this before? Any recommendations?
I did find Core Plot, but it seems to be in the early stages of development.
Edit to add some details of requirements (as they currently stand 😉 )
- Bar Charts
- Horizontal bar charts
- Double stacked bar charts
- Axis labels (including rotated 90 degrees on the y axis)
- Labels above each bar on the chart
- Shaded or custom backgrounds
