API
Warning: Do not use the same id
for multiple charts, as it will put multiple charts in the same container
Props:
id: string
: A unique identifier for the div surrounding the chart. Default:undefined
.className: string
: Adds aclassName
to the div container. Default:undefined
.style: React.CSSProperties
: Adds a style object to the div container. Default:{width: 100}
.marginInPercent: number
: Sets the margin for the chart inside the containing SVG element. Default:0.05
.value: number
: The value of the gauge. Default:0
.minValue: number
: The minimum value of the gauge. Default:0
.maxValue: number
: The maximum value of the gauge. Default:100
.arc: object
: The arc of the gauge.cornerRadius: number
: The corner radius of the arc. Default:7
.padding: number
: The padding between subArcs, in rad. Default:0.05
.width: number
: The width of the arc given in percent of the radius. Default:0.2
.nbSubArcs: number
: The number of subArcs. This overridessubArcs
. Default:undefined
colorArray: Array<string>
: The colors of the arcs. This overridessubArcs
colors. Default:undefined
subArcs: Array<object>
: The subArcs of the gauge.limit: number
: The subArc limit value. When no limits are defined in the next subArcs in the list, it’s optional and will auto-calculate remaining arcs limits. Example:[{limit: 70}, {}, {}, {}]
. In a defaultminValue/maxValue
, the values will be equal to[{limit: 70}, {limit: 80}, {limit: 90}, {limit: 100}]
. But[{},{limit: 100}]
will not work properly as the not defined subArc limit has a subArc with limit defined ahead in the array.color: string
: The subArc color. When not provided, it will use default subArc’s colors and interpolate first and last colors when subArcs number is greater thancolorArray
.showMark: boolean
: Whether or not to show the mark. Default:false
.tooltip: object
: Tooltip object.text: string
text that will be displayed in the tooltip when hovering the subArc.style: React.CSSProperties

.hide: boolean
: Whether or not to hide the value label. Default:false
.
markLabel: object
The markLabel of the gauge.type: string
: This makes the marks"inner"
or"outer"
the radius. Default:"outer"
hideMinMax: boolean
: Whether or not to hide the min and max labels. Default:false
marks: Array<object>
: The marks of the gauge. When not provided, it will use default gauge marks with five values.value: number
: The value of the mark.valueConfig: object

: The char of the mark. Default:'_'
charSize: number
: The font size of the mark’s char. Default:30
charColor: string
: The font color of the mark’s char. Default:#464A4F
hide: boolean
: Whether or not to hide the mark’s char. Default:false
##### Colors for the chart
The colors could either be specified as an array of hex color values, such as ["#FF0000", "#00FF00", "#0000FF"]
where
each arc would a color in the array (colors are assigned from left to right). If that is the case, then the length of the array
must match the number of levels in the arc.
If the number of colors does not match the number of levels, then the first and the last color from the colors array will
be selected and the arcs will get colors that are interpolated between those. The interpolation is done using d3.interpolateHsl.
