Periods

Periods is an array of objects that allows users to specify the range of periods. The “interval” property specifies the count value of the button, and the “text” property specifies the text to be displayed on button. The “intervalType” property allows users to customize the intervals of the buttons. The “intervalType” property supports the following interval types:

Auto
