Point out the mistake in solution provided for homework from video titled "Making Your Own Shot and Pass Maps"

[Ujjval-Patel]

First of all, I would like to say kudos, you are doing a wonderful job. ( feeling inarticulate to express my gratitude ).

Although. In the video titled, "Making Your Own Shot and Pass Maps". David provided the solution of how passes where plotted. Now I was trying to see recreate similar map for Dani Carvajal famous cross from which Cristiano Ronaldo scored that famous bicycle kick in the champions league semifinal. But to my surprise, there was no such 'pass' created by 'Dani Carvajal'. Here's my observation.

1. Solution provided by David.
   passArrow = plt.Arrow(x,pitchWidthY-y,dx,dy, width=3, color="blue")
   result
   

2. Correct code in my opinion.
   passArrow = plt.Arrow(x,pitchWidthY-y,dx,-dy, width=3, color="blue")
   result
   

Thank you.
