示例1: domainExtent
export function domainExtent(numValues: number[], scaleType: 'linear' | 'log'): [number, number] {
const filterValues = scaleType === 'log' ? numValues.filter(v => v > 0) : numValues
const [minValue, maxValue] = extent(filterValues)
if (minValue !== undefined && maxValue !== undefined && isFinite(minValue) && isFinite(maxValue)) {
if (minValue !== maxValue) {
return [minValue, maxValue]
} else {
// Only one value, make up a reasonable default
return scaleType === 'log' ? [minValue/10, minValue*10] : [minValue-1, maxValue+1]
}
} else {
return scaleType === 'log' ? [1, 100] : [-1, 1]
}
}示例2: constructor
constructor(xSource: DataFrame, scaleConfig: ScaleConfig) {
super(xSource, scaleConfig);
var props = this.scaleConfig;
var vars = d3.extent(this.vars);
var min = Number.isFinite(props.min) ? props.min : vars[0];
var max = Number.isFinite(props.max) ? props.max : vars[1];
this.vars = [
Math.min(...[min, vars[0]].filter(Number.isFinite)),
Math.max(...[max, vars[1]].filter(Number.isFinite))
];
this.addField('scaleType', 'size');
this.addField('funcType', scaleConfig.func || 'sqrt');
