Hi murchak,
I tested your VI on LV2011SP1 and see the same display bug as you do.
But I also found a workaround:
- Changing the line width alone doesn't help.
- Changing the point style does help showing the line!
So you need to change the plot style to show points too, even the smallest point is sufficient (and doesn't get recognized by the user)!.
See exported simplified image:
(I used bigger points for demonstration…)
