The chart represents the rate at which any player is transferred in or out in current game week. EG: if the score of a player is +50, it means that he is being transferred in at the rate of 50 for every single transfer out. And vice-versa for -ve scores.
25 players each of highest scores from +ve and -ve values are plotted. Rest are ignored.
If the FPL cost of player is changed during the week (price rise or drop), the color of the marker representing the player is changed accordingly.
As always, this table will be directly placed on under the menu 'Season 16/17' to make it always easily accessible. Hope everybody finds it useful. Till next post.
