示例1: drawSimpleOpacityLegend
function drawSimpleOpacityLegend(elem, options) {
let legendElem = $(elem).find('svg');
clearLegend(elem);
let legend = d3.select(legendElem.get(0));
let legendWidth = Math.floor(legendElem.outerWidth());
let legendHeight = legendElem.attr("height");
if (legendWidth) {
let legendOpacityScale;
if (options.colorScale === 'linear') {
legendOpacityScale = d3.scaleLinear()
.domain([0, legendWidth])
.range([0, 1]);
} else if (options.colorScale === 'sqrt') {
legendOpacityScale = d3.scalePow().exponent(options.exponent)
.domain([0, legendWidth])
.range([0, 1]);
}
let rangeStep = 10;
let valuesRange = d3.range(0, legendWidth, rangeStep);
var legendRects = legend.selectAll(".heatmap-opacity-legend-rect").data(valuesRange);
legendRects.enter().append("rect")
.attr("x", d => d)
.attr("y", 0)
.attr("width", rangeStep)
.attr("height", legendHeight)
