Hi All,
I basically want to produce a graph like the following:

Which I have managed to do so by using the option phase in IR control chart. But when the control chart is produced the y axis ranges from 3 to -4. But I have got 2 reference lines @ y=3 and y=-3.
So when I extend the axis of y by right clicking on Y axis > Size/Scale>Y Axis> and changing maximum value from 3 to 4. This works fine.
But the problem I am facing is that when I do the above, it for some reason doesnt extend the phase lines (so for example in the link mentioned above, it doesnt extend the blue dotted line, that seperates the 2 control charts)
Any idea on how I can do that?
Thanks in advance.
