title: Including graph images in an email sent from Application
body: <p>I'm using Core Plot for charting in my app. One of the use scenarios for the app requires me to implement sending emails with the charts - from the default email client. </p>
  
  <p>I'm wondering what would be the best way to implement it - as in a single email there could be as many as 40 charts included... I could render the chart, then use the contents of its view as CoreGraphics context and, I guess, generate CGImage and UIImage from there, then somehow include it in an email... but I'm wondering if there isn't a simpler way to achieve it? </p>
  
  <p>One option would be, of course, to use Core Plot for the in-app plotting, and in the email use some online library for the plots - like Google Charts (so, instead of having the images attached or inline in the mail, I could just use <code>&lt;img src="..." /&gt;</code> instead - but I'm not sure if it's what I should really do (I don't want to use Google Chart entirely for my charting, as the app should be usable without internet access)... </p>
  
  <p>What would be the best way to generate the charts for sending in an email? </p>
  
  <p>(Or maybe there's a better way to send it? Something like generating a PDF report with graphs inside?) </p>
