equal price labels on Y axis

I would like to see equal spacing regardless of zoom level on the Y axis, at the moment as can be seen here from 3 products the Y axis pricing is not equal, for instance with the Yen I`d like to be able to see 148.50, 148.70, 148.90 (20 point jumps), this could be anything you set it to, 50 pips, 20 pips, 100 pips etc, as long as the labels have equal spacing. (this is available in metatrader and ninjatrader).  In ninjatrader as you zoom in and out of the chart, the main price labels are maintained, they do not change, zooming in fills in other price labels on the Y axis but maintains those major divisions.
