Place the Y grid dynamically based on the graph's Y range. The algorithm ensures that you always have a grid, that there are enough but not too many grid lines, and that the grid is metric. That is the grid lines are placed every 1, 2, 5 or 10 units. This parameter will also ensure that you get enough decimals displayed even if your graph goes from 69.998 to 70.001.
