dccRangeSlider: RangeSlider component

In dash: An Interface to the Dash Ecosystem for Authoring Reactive Web Applications

RangeSlider component

Description

A double slider with two handles. Used for specifying a range of numerical values.

Usage

dccRangeSlider(id=NULL, min=NULL, max=NULL, step=NULL, marks=NULL,
value=NULL, drag_value=NULL, allowCross=NULL,
className=NULL, count=NULL, disabled=NULL, dots=NULL,
included=NULL, pushable=NULL, tooltip=NULL, vertical=NULL,
verticalHeight=NULL, updatemode=NULL, loading_state=NULL,
persistence=NULL, persisted_props=NULL,
persistence_type=NULL)

Arguments

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.
min	Numeric. Minimum allowed value of the slider
max	Numeric. Maximum allowed value of the slider
step	Numeric. Value by which increments or decrements are made
marks	List with named elements and values of type character | lists containing elements 'label', 'style'. those elements have the following types: - label (character; optional) - style (named list; optional). Marks on the slider. The key determines the position (a number), and the value determines what will show. If you want to set the style of a specific mark point, the value should be an object which contains style and label properties.
value	List of numerics. The value of the input
drag_value	List of numerics. The value of the input during a drag
allowCross	Logical. allowCross could be set as true to allow those handles to cross.
className	Character. Additional CSS class for the root DOM node
count	Numeric. Determine how many ranges to render, and multiple handles will be rendered (number + 1).
disabled	Logical. If true, the handles can't be moved.
dots	Logical. When the step value is greater than 1, you can set the dots to true if you want to render the slider with dots.
included	Logical. If the value is true, it means a continuous value is included. Otherwise, it is an independent value.
pushable	Logical | numeric. pushable could be set as true to allow pushing of surrounding handles when moving an handle. When set to a number, the number will be the minimum ensured distance between handles.
tooltip	Lists containing elements 'always_visible', 'placement'. those elements have the following types: - always_visible (logical; optional): determines whether tooltips should always be visible (as opposed to the default, visible on hover) - placement (a value equal to: 'left', 'right', 'top', 'bottom', 'topleft', 'topright', 'bottomleft', 'bottomright'; optional): determines the placement of tooltips see https://github.com/react-component/tooltip#api top/bottom* sets the _origin_ of the tooltip, so e.g. 'topleft' will in reality appear to be on the top right of the handle. Configuration for tooltips describing the current slider values
vertical	Logical. If true, the slider will be vertical
verticalHeight	Numeric. The height, in px, of the slider if it is vertical.
updatemode	A value equal to: 'mouseup', 'drag'. Determines when the component should update its 'value' property. If 'mouseup' (the default) then the slider will only trigger its value when the user has finished dragging the slider. If 'drag', then the slider will update its value continuously as it is being dragged. Note that for the latter case, the 'drag_value' property could be used instead.
loading_state	Lists containing elements 'is_loading', 'prop_name', 'component_name'. those elements have the following types: - is_loading (logical; optional): determines if the component is loading or not - prop_name (character; optional): holds which property is loading - component_name (character; optional): holds the name of the component that is loading. Object that holds the loading state object coming from dash-renderer
persistence	Logical | character | numeric. Used to allow user interactions in this component to be persisted when the component - or the page - is refreshed. If 'persisted' is truthy and hasn't changed from its previous value, a 'value' that the user has changed while using the app will keep that change, as long as the new 'value' also matches what was given originally. Used in conjunction with 'persistence_type'.
persisted_props	List of a value equal to: 'value's. Properties whose user interactions will persist after refreshing the component or the page. Since only 'value' is allowed this prop can normally be ignored.
persistence_type	A value equal to: 'local', 'session', 'memory'. Where persisted user changes will be stored: memory: only kept in memory, reset on page refresh. local: window.localStorage, data is kept after the browser quit. session: window.sessionStorage, data is cleared once the browser quit.

Value

named list of JSON elements corresponding to React.js properties and their values

Examples

if (interactive()) {
    library(dash)

    app <- Dash$new()

    app$layout(
      htmlDiv(
        dccRangeSlider(
          count = 1,
          min = -5,
          max = 10,
          step = 0.5,
          value = list(-3, 7),
          marks = as.list(
            setNames(-5:10, as.character(-5:10))
          )
        )
      )
    )

  app$run_server()
}
