I was in a big doubt since very long time,I was waiting for the new version of the Charts under the Spark Components,so that I can use them inside the mobile applications.But I was surprised also that why there is nothing for this in the Spark components.But Yesterday I just checked with the MX Charts components in my mobile application for a demo on my Samsung mobile,and things were working excellent and smooth.Was happy and surprised also that how is it is it possible?. Later on started to search on the net for this.And found it on my first click.It was clearly mention there at http://www.adobe.com/devnet/flex/articles/mobile-development-flex-flashbuilder.html#articlecontentAdobe_numberedheader_1 by Narciso Jaramillo long long ago that:-.
Charts are supported in mobile projects, but other MX components are not. We don’t recommend using MX components in mobile projects; use the Spark components instead. The one exception is the charting components, which are usable in mobile projects if care is taken to avoid displaying or animating too much data at once.
So finally I have to made myself satisfy with ‘Better late than never.’
Hence sharing it,hope this can help someone.
