Core Plot slow on iPod Touch 2nd gen?

I'm using Core Plot to develop some iOS applications, but zooming and p开发者_Python百科anning seems to be sort of slow and jerky on my iPod Touch 2nd gen (it looks fine in simulator). Is the device just slow? Should it look better on more recent iPhones and such? I can't get any of the examples to deploy to the iPod so I can't see how they do.

The simulator uses the power of your computer to simulate the user interface and (a lot of) the software of an iOS device, not it's hardware. It is well possible the limited amount of memory and CPU of a second generation iPod Touch (not supported by the latest version of the OS for these reasons) can have issues with the heavy rendering made by Core Pot. Latest devices do have more powerful gear, but are still way more constrained than your computer. If Core Plot s unusable on your device, it may still feel sluggish on other, more recent, devices because of a faulty implementation. Perhaps you could share with us some code of your integration or describe the type and quantity of data used by your app?
