VictoryBrushContainer
VictoryBrushContainer
adds the ability to highlight a region of a chart, and interact with
highlighted regions, either by moving the region, expanding the region, or selecting a new region.
VictoryBrushContainer
is useful for selecting a region of a larger dataset by domain. Create a
brush control by tying the domain of the selected region to the domain of a separate chart.
See the brush and zoom guide for an example of using VictoryBrushContainer
to create a brush
control.
VictoryBrushContainer
is similar to VictorySelectionContainer
. VictoryBrushContainer
may be
used to identify the domain of a selected region, whereas VictorySelectionContainer
may be used to
identify a list of data points within a selected region. VictoryBrushContainer
will also create
persistent highlighted regions, whereas regions created by VictorySelectionContainer
disappear after onMouseUp
events.
VictoryBrushContainer
may be used with any Victory component that works with an x-y coordinate
system, and should be added as the containerComponent
of the top-level component.
However, the component that uses it must be standalone
(standalone={true}
), which is the default for all top-level Victory components.
VictoryBrushContainer
uses a superset of props used by VictoryContainer. All props are optional.
allowDrag
type: boolean
The optional allowDrag
prop accepts a boolean that enables dragging behavior for the highlighted brush area. Resizing will still be enabled when the allowDrag
prop is set to false.
default: allowDrag={true}
allowDraw
type: boolean
The optional allowDraw
prop accepts a boolean that enables drawing new brush areas. When this prop is set to false, existing brush areas may still be resized or dragged, but clicking outside of existing brush areas will not trigger the creation of new brush areas.
default: allowDraw={true}
allowResize
type: boolean
The optional allowResize
prop accepts a boolean that enables resizing the highlighted brush area. Dragging will still be enabled when the allowResize
prop is set to false, but the dimensions of the brush area will be fixed. By default, when allowResize
is set to false, clicking outside of the brush area will center the brush on the user's mouse position without resizing it. This behavior can be controlled via the defaultBrushArea prop.
default: allowResize={true}
brushComponent
type: element
The brushComponent
prop specifies the component to be rendered for the highlighted area.
This component will be supplied with the following props: x, y, width, height, and style.
When this prop is not specified, a <rect/>
will be rendered.
default: brushComponent={<rect/>}
brushDimension
type: "x" || "y"
When the brushDimension
prop is set, brushing will only be specific to the given dimension
(either "x" or "y"), and the entire domain of the other dimension will be highlighted. When this prop
is not specified, highlighting will occur along both dimensions.
example: brushDimension="x"
brushDomain
type: { x: [low, high], y: [low, high] }
The optional brushDomain
prop describes the highlighted state. This prop is an object that
specifies separate arrays for x
and y
. Each array is a tuple that describes the minimum and maximum
values to render. If this prop is not provided initially, the chart will render with the entire
domain highlighted. When this prop changes, the chart will render with a new highlighted domain.
example: brushDomain={{x: [50, 100], y: [0, 100]}
brushStyle
type: object
The brushStyle
adds custom styles to the brushComponent
. This prop should be given as
an object of SVG style attributes.
default: brushStyle={{stroke: "transparent", fill: "black", fillOpacity: 0.1}}
defaultBrushArea
type: "all", "none", "disable", "move"
The defaultBrushArea
prop specifies how the container will behave when a region outside the active brush is clicked without selecting a new area. When the prop is set to "all", the entire domain will be selected. When the prop is set to "none", no new region will be selected, and any existing active brush will be cleared. When the prop is set to "disable" the new selected region will default to the current active brush. When this prop is set to "move", the active brush will be moved so that it is centered over the location of the click event.
disable
type: boolean
When the disable
prop is set to true
, VictoryBrushContainer
events will not fire.
handleComponent
type: element
The handleComponent
prop specifies the component to be rendered for each handle for the highlighted
area. This component will be supplied with the following props: x
, y
, width
, height
, cursor
, and style
.
When this prop is not specified, a <rect/>
will be rendered.
default: handleComponent={<rect/>}
handleStyle
type: object
The handleStyle
adds custom styles to the handleComponents
. This prop should be given as
an object of SVG style attributes.
Handles refer to the region on each highlighted area where the area may be
expanded. Only handles relevant to the given dimension
will be rendered. For example, when
brushDimension="x"
only "left" and "right" handles will be rendered. Handles are automatically styled
with cursors appropriate to their orientation.
default: `handleStyle={{stroke: "transparent", fill: "transparent"}}
handleWidth
type: number
The handleWidth
prop specifies the size of the rendered handle component in pixels. This prop will determine the width of "left" and "right" handles and the height of "top" and "bottom" handles.
default: handleWidth={8}
onBrushCleared
type: function
The optional onBrushCleared
prop accepts a function to be called when the active brush area is cleared. The function accepts the parameters of domain
(the updated domain), and props
(the props used by VictoryBrushContainer
).
example: onBrushCleared={(domain, props) => handleBrushCleared(domain, props)}
onBrushDomainChange
type: function
The optional onBrushDomainChange
prop accepts a function to be called on each update to the highlighted domain. The function accepts the parameters of domain
(the updated domain), and props
(the props used by VictoryBrushContainer
).
example: onBrushDomainChange={(domain, props) => handleDomainChange(domain, props)}
onBrushDomainChangeEnd
type: function
The optional onBrushDomainChangeEnd
prop accepts a function to be called only on mouse up events. The function accepts the parameters of domain
(the updated domain), and props
(the props used by VictoryBrushContainer
).
example: onBrushDomainChangeEnd={(domain, props) => handleDomainChangeEnd(domain, props)}
