Scatter Chart with lines

[#1]

Hello all together,

i need help for my scatter chart.

I want to draw a straight line between the points of my artwork throught the zero point.
Example: I have 2 points (2/1) and (2/2) and both should have a straight with zero point (0/0).

But i have mor Point than these 2!
How can i do that?

I am looking forward,

Thanks

J.D.
