(For example)
・Suppose the current price on the y-axis is 300.
・If you specify 10% above and 10% below, the y-axis price scale will be 270-330 and the current price of 300 will be displayed in the middle
・If you specify 30% above and 10% below, the y-axis price scale will be 270-390 and the current price of 300 will be displayed in the quarter from the bottom.
Thank you.
