我在react-vis图上绘制了9种不同的线条系列。这些线序列的值是不同的。最小范围在0-4之间,最大范围在0- 12000之间(图1)。当我绘制所有这些线列时,它们大多数都坐在图的底部,可读性不够好。

我试过使用yDomain={[0, 100]}。然而,我现在看到的是,图形的最大值最终是100,并且所有其他值大于100的线列是不可见的(它们被绘制在我们可以看到的上方)。

如果这有帮助,下面是一个代码示例:

</FlexibleWidthXYPlot>我想要的是每个线系列被感知地缩放到0-100%的范围,而不修改实际值。我需要这些值仍然显示,因为我正在使用十字准线来显示它们。

这是一个示例,我如何缩放两个图表(一个值以百万为单位,第二个以百分比为单位),以同时在一个图表上显示。
export const getBound = (arr, key, max = true) => {
if (!Array.isArray(arr)) {
return false
}
// `${key}0` is a check for graphs that has y0 and x0 values, for example Bar Charts
const key0 = `${key}0`
let result = max ? 0 : Number(arr[0][key])
arr.forEach(item => {
if (max) {
if (Number(item[key]) > result || (item[key0] && Number(item[key0]) > result)) {
result = item[key0] ? (Number(item[key]) > Number(item[key0])
? Number(item[key]) : Number(item[key0])) : Number(item[key])
}
} else {
if (Number(item[key]) < result || (item[key0] && Number(item[key0]) < result)) {
result = item[key0] ? (Number(item[key]) < Number(item[key0])
? Number(item[key]) : Number(item[key0])) : Number(item[key])
}
}
})
return result
}
export const getScaleValues = (arr1, arr2, roundTicksTo = 5) => {
const arr1AbsMax = Math.abs(getBound(arr1, 'y')) > Math.abs(getBound(arr1, 'y', false))
? Math.abs(getBound(arr1, 'y')) : Math.abs(getBound(arr1, 'y', false))
const arr2AbsMax = Math.abs(getBound(arr2, 'y')) > Math.abs(getBound(arr2, 'y', false))
? Math.abs(getBound(arr2, 'y')) : Math.abs(getBound(arr2, 'y', false))
const coef = arr1AbsMax / arr2AbsMax
const scaled = arr2.map(item => {
return Object.assign({}, item, {
y: item.y * coef,
})
})
const ticksFormat = (v) => formatPercentageTicks(v, coef, roundTicksTo)
return {
coef: coef,
scaled: scaled,
ticksFormat: ticksFormat,
}
}
export const formatPercentageTicks = (value, coef, roundTo = 1) => {
return `${round(value / (coef), roundTo)} %`
}
export const round = (num, roundTo) => {
return num % roundTo < (Math.ceil(roundTo / 2))
? (num % roundTo === 0 ? num : Math.floor(num / roundTo) * roundTo) : Math.ceil(num / roundTo) * roundTo
}如果你有9行,你可以将1作为默认值,并将其他8行作为默认值的%。此外,默认的YAxis将显示数字,您可以在右侧为%添加额外的Yaxis:
<YAxis orientation={'right'} tickFormat={v => scaledObj.ticksFormat(v)} />https://stackoverflow.com/questions/57765932
