If the Coretek solution does not work for you, since it is not for me, I found this solution to get the desired result:
YOURPLOT.getGraphWidget().setGridPaddingRight(AmountOfSpaceDesired); YOURPLOT.getGraphWidget().setGridPaddingTop(AmountOfSpaceDesired);
This will not only cause your axis to stop clipping, but also your schedule. I wanted a little more space on the top where I used to have a point touching the right side, where another point was touching.
Hope this helps someone as it helps me.
