Hi

As part of some courseowrk I have been observing cells in culture and plotting their movements as simple x-y co-ordinates. I have ploted the data on a scatter graph in excel which shows the tracks of the movement of each cell.

However my tutor wants me to show the directionality of the cells by plotting them from the same point of origin to create a kind of "sunburst" effect - do all the cells splay out in different directions or are they all moving the same way towards something?

The data I have is the x and y co-ordinates and the distance each cell has travelled between all the co-ordinate points.

Is this even possible? Hope someone can help
Regards,
Nik
