Horizontal Grid Lines at Price Intervals

[Quicktrader10]

How do I change the spacing of the horizontal grid lines on the price bar chart? I opened an ES chart, 3 min time frame, and the horizontal grid lines are spaced 1.5 points apart. On a 1 min. chart they are spaced 0.75 points apart. A 2 min ES chart has 1.5 point spacing. Can this spacing be changed? Thank you.

Grid lines are automatically generated and can not be manualy edited. Custom grid lines is on our production schedule for NT6.1 later this year.
