Hi Vishwas.
thanks for your reply.
“ohter forum thread” does not have “0” in the Y-axis scale, so the split line is just not visible.
( dataPoints: [{ x: 10, y: 20 }, … -> { x: 10, y: 0 })
I found that by making the line color transparent, the line under the label disappears from view.
This is what I wanted to do.
Another way to do this is to add “thickness:0” to “stripLines.push”.
