示例1: drawColorLegend

function drawColorLegend(elem, colorScheme, rangeFrom, rangeTo, maxValue, minValue) {
  let legendElem = $(elem).find('svg');
  let legend = d3.select(legendElem.get(0));
  clearLegend(elem);

  let legendWidth = Math.floor(legendElem.outerWidth()) - 30;
  let legendHeight = legendElem.attr("height");

  let rangeStep = 1;
  if (rangeTo - rangeFrom > legendWidth) {
    rangeStep = Math.floor((rangeTo - rangeFrom) / legendWidth);
  }
  let widthFactor = legendWidth / (rangeTo - rangeFrom);
  let valuesRange = d3.range(rangeFrom, rangeTo, rangeStep);

  let colorScale = getColorScale(colorScheme, maxValue, minValue);
  legend.selectAll(".heatmap-color-legend-rect")
    .data(valuesRange)
    .enter().append("rect")
    .attr("x", d => d * widthFactor)
    .attr("y", 0)
    .attr("width", rangeStep * widthFactor + 1) // Overlap rectangles to prevent gaps
    .attr("height", legendHeight)
    .attr("stroke-width", 0)
    .attr("fill", d => colorScale(d));

  drawLegendValues(elem, colorScale, rangeFrom, rangeTo, maxValue, minValue, legendWidth);
}
