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.

<VictoryChart
  containerComponent={
    <VictoryBrushContainer
      brushDimension="x"
      brushDomain={{x: [0.1, 0.3]}}
    />
  }
>
  <VictoryLine />
</VictoryChart>

Props

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}

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 fized.

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 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}}

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”}}

onBrushDomainChange

type: function

The optional onBrushDomainChange prop accepts an 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) => handeDomainChange(domain, props)}
