VictoryZoomContainer provides pan and zoom behavior for any Victory component that works with an x, y axis. Zoom events are controlled by scrolling, and panning events are controlled by dragging. See an example of a zoomable chart

VictoryZoomContainer 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 domainPadding={{ y: 10 }}
  containerComponent={
    <VictoryZoomContainer/>
  }
>
  <VictoryScatter
    y={(datum) => Math.sin(2 * Math.PI * datum.x)}
  />
</VictoryChart>

Props

VictoryZoomContainer uses a superset of props used by VictoryContainer. All props are optional.

allowPan

type: boolean

The optional allowPan prop accepts a boolean that enables the panning functionality. Zooming will still be enabled when the allowPan prop is set to false.

default: allowPan={true}

allowZoom

type: boolean

The optional allowZoom prop accepts a boolean that enables the zoom functionality. Panning will still be enabled when the allowZoom prop is set to false.

default: allowZoom={true}

clipContainerComponent

type: element

VictoryZoomContainer works by clipping data outside of a given domain. VictoryZoomContainer uses VictoryClipContainer by default. This prop should not be replaced with a custom component, but you may want to set props on VictoryClipContainer, such as clipPadding

example: clipContainerComponent={<VictoryClipContainer clipPadding={{top: 10, right: 10}}}/>}

disable

type: boolean

When the disable prop is set to true, VictoryZoomContainer events will not fire.

downsample

type: number || boolean

The downsample prop limits the number of points that will be displayed. This prop may be given as a boolean or a number corresponding to maximum number of points. When given as a boolean, the maximum number of points that will be plotted is 150.

minimumZoom

type: { x: number, y: number }

The minimumZoom prop sets a minimum domain extent for the zoomed chart. When the difference between the maximum and minimum of a zoomed domain is equal to the minimumZoom in either dimension, the component will stop responding to events that would normally trigger zooming in. Zooming out and panning will still be enabled. When this prop is not specified, the default minimum zoom will cover 1 / 1000th of the original domain. This prop should be given as an object with numeric values for x and y.

example: minimumZoom={{x: 1, y: 0.01}}

onZoomDomainChange

type: function

The optional onZoomDomainChange prop accepts an function to be called on each update to the visible domain. The function accepts the parameters domain (the updated domain) and props (the props used by VictoryZoomContainer).

example: onZoomDomainChange={(domain, props) => handleDomainChange(domain, props)}

zoomDomain

type: { x: [low, high], y: [low, high] }

The zoomDomain prop describes the zoomed 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 without an initial zoom, displaying the entire dataset. Updates to zoomDomain will trigger a re-render of the chart with the new domain.

example: zoomDomain={{x: [0, 100]}}

zoomDimension

type: "x" || "y"

When the zoomDimension prop is set, panning and zooming will be restricted to the given dimension (either x or y), and the domain of the other dimension will remain static. When this prop is not specified, both x and y dimensions will pan and zoom.

example: zoomDimension="x"

Changelog

31.0.0 (2018-11-10)

• #1177 Adds support for controlling radius, innerRadius, cornerRadius, padAngle, sliceStartAngle and sliceEndAngle for each individual slice of a pie:

Details: The Slice primitive used by VictoryPie now takes radius, cornerRadius, innerRadius, padAngle, sliceStartAngle and sliceEndAngle props. Each of these props may be given as number or a function of datum and active. padAngle, radius, cornerRadius and innerRadius will be passed down from props on VictoryBar, but sliceStartAngle and sliceEndAngle must be defined directly on the Slice instance, These values should be given in degrees. To make these values easier to use as functional props, startAngle, endAngle, and padAngle (in degrees) are added to each datum passed into Slice. (If your data already has these properties they will not be overridden)

Breaking Changes The Slice primitive will still take a pathFunction prop, but this prop will no longer be provided by VictoryPie. This will not be a breaking change for most users. This will only affect users who were wrapping the Slice component and making use of the pathFunction prop provided by VictoryPie Users who were providing their own pathFunction prop to Slice should not be effected.
