VictoryHistogram
VictoryHistogram renders a dataset as series of bars representing "bins", allowing the ability to view distribution of the data. The data passed in will be "binned" according to the bin
prop that is provided (if any), allowing for flexibility in how these bins are determined. VictoryHistogram can be composed with VictoryChart
to create histogram charts.
VictoryHistogram
is intended to be used with quantitative data. Please use VictoryBar
for qualitative or categorical data.
animate
type: boolean || object
VictoryHistogram
uses the standard animate
prop. Read about it here
See the Animations Guide for more detail on animations and transitions
animate={{
duration: 2000,
onLoad: { duration: 1000 }
}}
bins
type: number || array[numbers] || array[dates]
default: undefined
VictoryHistogram
uses d3.bin
to do binning.
The bins
prop is used to specify how the data will be binned. There are a few options for this, the first being passing no value, ie the default behavior, which is letting d3.bin
generate the buckets based on the data. The second is passing a number, which specifies approximately the number of bins to generate, this is not a guarantee (see d3.bin
for more details). The last options are passing an array of numbers or dates (depending on the data), this array represents an array of thresholds. So for example if the bin prop provided is [0, 10, 20, 35]
, this would result in 3 bins, that would look like [0, 10) , [10, 20), [20, 35].
This prop allows for a lot of flexibility in how the data is displayed. For example it is possible to have uneven sized bins if so desired. It is also possible to group the data by days, weeks, or years.
binSpacing
type: number
The binSpacing
prop is used to specify space between each bin. binSpacing
represents the number of pixels that will be between each bin (including at the beginning and end of the bins). By default, bins are rendered with no spacing.
containerComponent
type: element
VictoryHistogram
uses the standard containerComponent
prop. Read about it here
containerComponent={<VictoryVoronoiContainer/>}
cornerRadius
type: function || number || { top, bottom, topLeft, topRight, bottomLeft, bottomRight }
The cornerRadius
prop specifies a radius to apply to each bar. If this prop is given as a single number, the radius will only be applied to the top of each bar. When this prop is given as a function, it will be evaluated for each bar with the props object corresponding to that bar.
data
type: array[object]
VictoryHistogram
uses the standard data
prop, except for it only expects each object within the array to have x
properties. The x
data accessor prop can be used to define a custom data format. Read about it here
Because each bar represents a bin rather than a particular data point (like with VictoryScatter
for example), when accessing datum
via a prop that passes datum
such as style
, datum will have properties x
, x0
, x1
, y
, and binnedData
. x
is the midpoint between the bin, x0
is the beginning of the bin, x1
is the end of the bin, y
is the aggregate amount of data points within that bin, and binnedData
is an array of the original data points that were grouped into this bin.
