dccInterval: Interval component
In dashCoreComponents: Core Interactive UI Components for 'Dash'

Description Usage Arguments Value Examples

A component that repeatedly increments a counter 'n_intervals' with a fixed time delay between each increment. Interval is good for triggering a component on a recurring basis. The time delay is set with the property "interval" in milliseconds.

1 2	dccInterval(id=NULL, interval=NULL, disabled=NULL, n_intervals=NULL, max_intervals=NULL)

`id`	Character. The ID of this component, used to identify dash components in callbacks. The ID needs to be unique across all of the components in an app.
`interval`	Numeric. This component will increment the counter 'n_intervals' every 'interval' milliseconds
`disabled`	Logical. If True, the counter will no longer update
`n_intervals`	Numeric. Number of times the interval has passed
`max_intervals`	Numeric. Number of times the interval will be fired. If -1, then the interval has no limit (the default) and if 0 then the interval stops running.
