to post images, you will need to:
1. save the image file (your graph) into your hard drive
2. upload it on the internet (plenty of free hosting sites out there like imgur.com, imageshack.com, etc etc). get the link for posting in forums
3. when you're making your post, click on the little icon that says "Insert Image" (it looks like a photograph of a little mountain). it will prompt you to insert the http link which you shld paste there.
oh and geeez, it's exactly what you needed
^^
I hope the lovely Wendy won't bite me for quoting one of her post
