I have a stock chart on which I'd like to adjust vertical gridlines' spacing. There's an option to adjust gridline spacing under horisontal axis options, for example to 5 units. Is there a way to adjust where the count starts while preserving the initial spacing of 5 for the rest of them? In other words, what I'd like to do is make it so that the first grid line appears at 3 for example, the next at 8, next at 12, 17, 22, 27 and so on. Or: first at 4, next at 9, next at 14, 19, 24 and so on. Is this possible? I'd like to keep the vertical axis where it is without adjusting it's position.

Thank you.
