drag and move a line

[Jerry Huang]

Hi every one !!

I followed this example to make line drag and move.
https://jsfiddle.net/3k2u8buk/

But my example always wrong coordinate.

(drag line) https://jsfiddle.net/taiwanhotdog/dbgjcj1v/

I don't know what 's wrong.

Can anyone tell me ?

Thank you.

Hi,

it seems the example is using

d3.event.dx
d3.event.dy

while your code is using

d3.event.x
d3.event.y
