Combo Chart, Add lower & Upper Spec Limit problems

[Bernieg]

Hi I'm trying to add Lower & Upper Spec Limits to a Combo Chart.
If the data is between LSL & USL then all Ok.
However if the data is between & inside/outside LSL & USL the chart X axis is wrong.
How do i get LSL & USL in the correct X axis position

Thanking you in Advance
Bernie
Thought about changing to LSL & USL to Scatter, but could not get it to work.
