In addition to Donald's comments, there is another possible solution : you can programmatically define the width of the Y scale, by playing with the digit number. As shown in the attached jpeg, you can decide of the overall number of digits, then read the max value of the Y axis and set programmaticaly the axis format.
In LV7, it is also possible to pad the scale labels with spaces, but I never could use this possibility programmatically.
