Changes for functional props and styles:
Related PR: #1360
Functional props like labels
and functional styles will now be called with a single argument instead of datum
and active
. The argument passed to functional props and styles will be an object containing all the props that control the rendering of the the target the prop applies to. Including things like datum
, active
, index
, data
, scale
, etc. We hope this will give users a lot more flexibility and control. In most cases, this change should be very straightforward to apply
old:
labels={(d) => `x: ${d.x}`}
new
labels={({ datum }) => `x: ${datum.x}`}
Gotchas:
cornerRadius
function that depends on barWidth
, do not also make barWidth
a function of some other prop.y
and x
, and tickFormat
. The arguments for these props have not changed.Changes for VictoryCandlestick
labels
Related PR: #1295
VictoryCandlestick
now has granular support for labels corresponding to each portion of the candle. The current labels
and labelComponent
props will be joined by new props corresponding to each part of the candle.
New props
lowLabels
lowLabelComponent
highLabels
highLabelComponent
openLabels
openLabelComponent
closeLabels
closeLabelComponent
This will be a breaking change affecting the positioning of the default label
. In earlier versions, the default label was positioned above the candle, it will now be positioned next to the center of the candle.
To use older label positioning, use highLabels
/ highLabelComponent
rather than label
/ labelComponent
. If you are using tooltips with VictoryCandlestick
, you will need to register a custom event to trigger your highLabels
tooltip:
example:
<VictoryCandlestick
highLabels={({ datum }) => datum.high}
highLabelComponent={<VictoryTooltip />}
events={[{
target: "data",
eventHandlers: {
onMouseOver: () => ({ target: "highLabels", mutation: () => ({ active: true }) }),
onMouseOut: () => ({ target: "highLabels", mutation: () => ({ active: false }) })
}
}]}
/>
The style
prop for VictoryCandlestick
now also has namespaces for the new labels in addition to the current labels
namespace. When both labels
and specific label styles (e.g. highLabels
) are provided, the styles will be merged
Changes for VictoryVoronoiContainer
Related PR: #1371
Before this version VictoryVoronoiContainer
had limited functionality for mouse-following tooltips, and for constraining a tooltip to the chart area, but it was only usable for multi-point tooltips (with voronoiDimension
), and was not user configurable. This version aims to correct these limitations:
mouseFollowTooltips
: This new boolean prop on VictoryVoronoiContainer
determines whether the labels should follow the mouse position or snap into place. (Note that in charts using voronoiDimension
, the tooltip still follows the mouse in the non-voronoiDimension
, as demonstrated in the charts below (both with voronoiDimension="x"
)mouseFollowLabels={true}
mouseFollowTooltips={false}
VictoryVoronoiContainer
will no longer be constrained to the chart area by default. Instead, add the constrainToVisibleArea
prop to VictoryTooltip
to enable this behavior for both multi-point and single point tooltips:
example:containerComponent={
<VictoryVoronoiContainer
labelComponent={<VictoryTooltip constrainToVisibleArea />}
/>
}
Changes for VictoryTooltip
and VictoryLabel
Related PR:#1371
The changes we wanted to make to support new behaviors in VictoryVoronoiContainer
required some changes to VictoryTooltip
and VictoryLabel
New props for VictoryTooltip
:
constrainToVisibleArea
is a boolean prop that, when true, will alter the position of the tooltip so that it exactly fits within the svg Victory renders. The tooltip's center will be moved, but the pointer will remain pointing at the associated x
, y
value of the tooltip. When this prop is set to true, pointerLength
may not be respected
center
is a prop that may be given as an object with values or functions for "x" and "y". When this prop is set, it will position the center of the tooltip (centered around the main body of the tooltip, minus the pointer). When this prop is not set, it will be calculated from other props such as x
, y
, pointerLength
, etc. This prop was added to enable mouse-following tooltips in VictoryVoronoiContainer
.
centerOffset
is a prop that may be given as an object with values or functions for "x" and "y". When this prop is set, the center of the tooltip will be offset by some amount from the x, y value it points to, resulting in a slanted pointer. When this prop is set, pointerLength
will not be respected (because the pointer will be slanted)
flyoutHeight
(formerly height
): This optional prop determines the height of the tooltip flyout (minus pointer). The name of this prop was changed so that it would not conflict with the height
prop now passed to VictoryTooltip
by its parents
flyoutWidth
(formerly width
): This optional prop determines the width of the tooltip flyout (minus pointer). The name of this prop was changed so that it would not conflict with the width
prop now passed to VictoryTooltip
by its parents
width
: the overall width of the parent svg. This prop will be passed down from any victory component that uses VictoryTooltip
as a label
height
: the overall height of the parent svg. This prop will be passed down from any victory component that uses VictoryTooltip
as a label
Changes Affecting VictoryLabel
and VictoryTooltip
x
and y
values passed to labels by their parent components have all been adjusted so that their values match the position of the data point they correspond to. All padding is now accounted for in the dx
and dy
props instead of being added directly to x
and y
.
This will be a breaking change for anyone who is wrapping label components and relying on the x
and y
props they receive, or providing their own dx
/ dy
props. These breaking changes may take a bit of manual adjustment to correct, but we hope this change will make label positioning easier to reason about in the long run.Other Changes
We have been concurrently working on improving performance and the stability of events in victory-native
. The following changes have been added to support these efforts:

prependDefaultAxes
boolean prop has been added to VictoryChart
. This prop will be set true by default in victory-native
to reduce the possibility of axis elements to interfere with events.Related PR: #1365

components)Changelog
32.0.0 (2019-02-27)
Horizontal Chart Improvements!
The goal of this change is to make it possible to turn any existing chart into a horizontal chart by adding the horizontal
prop to the chart without needing to alter any other props.
x
value always refers to the independent dimension, and the y
value always refers to the dependent dimension.VictoryAxis
components is no longer tied to whether or not they are the dependentAxis
Breaking Changes
Most Horizontal Charts
The change in how props with x and y values are treated (i.e. scale
, domain
, etc) will be a breaking change for most horizontal charts. In most cases, reversing the x
and y
values of props you are providing to your horizontal chart will be sufficient to correct the change. For example:
<VictoryChart horizontal scale={{ x: "log" }} domain={{ y: [4, 9] }}>
<VictoryBar
data={[
{ x: 5, y: 0.1 },
{ x: 6, y: 1 },
{ x: 7, y: 10 },
{ x: 8, y: 100 }
]}
/>
</VictoryChart>
Should be changed to:
<VictoryChart horizontal scale={{ y: "log" }} domain={{ x: [4, 9] }}>
<VictoryBar
data={[
{ x: 5, y: 0.1 },
{ x: 6, y: 1 },
{ x: 7, y: 10 },
{ x: 8, y: 100 }
]}
/>
</VictoryChart>
Props affected by this change are: scale
, domain
, maxDomain
, minDomain
, domainPadding
, and categories
Horizontal Charts with Event Containers
Dimension props such as brushDimension
have changed so that they always refer to the dimension of the target variable (x for the independent variable, and y for the dependent variable). For example, a VictoryBrushContainer
component with brushDimension="x"
will move and expand only in the independent dimension regardless of whether the chart is horizontal.
Props affected by this change are: brushDimension
, cursorDimension
, selectionDimension
, voronoiDimension
, and zoomDimension
Horizontal Charts with Custom dataComponents
The position values (i.e. x
, y
, x0
, y0
) supplied to custom dataComponents
from components like VictoryChart
will be scaled for the layout of the horizontal chart. Users who rely on these values may need to flip them or adjust them depending on their use case
Horizontal VictoryBoxPlot
Previously VictoryBoxPlot
required data to be flipped (x values flipped with y values) in order to plot horizontal charts. This is no longer required, and providing data in this format will no longer work correctly. To correct for this change, it should be sufficient to flip the data used in horizontal charts
