Would you buy an API to convert your data into a particular graph which you can show in your email (as image)? How often for your projects you come across this situation and need help with that?
@shree not sure if market is big enough to afford another similar competitor, I wasn't aware of them thanks for bringing them up.
There was also one called chartspree. (Better than imagechart) They, however, shut the project.
I could envision a service that provides easy graphing functionality, whether by an SDK or API, to developers. Graphing libraries, especially on Android and I assume iOS, are pretty rusty; an easy to use services would certainly be worth a few bucks.
It is a nice idea. There are services like www.image-charts.com which do just that.
