If enabled, auto-scaling will dynamically reduce the size of chart points and other chart elements based on the number of chart points you have selected for display. When enabling a large number of chart points, you may find it helpful to enable this option to better accommodate the extra data.
Good to Know
When enabled, auto-scaling starts to apply once ten (10) or more chart points are displayed. It then gradually reduces the size of the chart points based on the quantity displayed. So the more chart points you enable, the smaller each of them will be.
