Change line segment in graph

1

How can I change only the first circle and the line that is linked to the other circle in a line chart? I used the following code:

lines.lines[0].attr({'stroke-width': 8});  

The goal is to change the width of the line. But this changes the whole line, and I just want to change the first segment of it. Is this possible?

Example: link
