I know this is a comupter forum but i need help with my maths course work as well as with excell. Can you do the scatter graphs on excell because it's very hard to draw them. And you know the squiggle at the beggining of the grpahs, how do you do them on excell because the stupid programme has put the data from 0-maximum value and it looks naff!!! So could i have some help please!!!

You tell it to do a scatter graph (it is an option) and not a line graph. To do the line of best fit right click on one of the points and "add trendline". Yu can't do the squiggle, but you can right click on the axis and "format axis" one of the options is start at or something, use that.
