示例1: addLogYAxis

  function addLogYAxis() {
    let log_base = panel.yAxis.logBase;
    let { y_min, y_max } = adjustLogRange(data.heatmapStats.minLog, data.heatmapStats.max, log_base);

    y_min = panel.yAxis.min && panel.yAxis.min !== '0' ? adjustLogMin(panel.yAxis.min, log_base) : y_min;
    y_max = panel.yAxis.max !== null ? adjustLogMax(panel.yAxis.max, log_base) : y_max;

    // Set default Y min and max if no data
    if (_.isEmpty(data.buckets)) {
      y_max = Math.pow(log_base, 2);
      y_min = 1;
    }

    scope.yScale = yScale = d3
      .scaleLog()
      .base(panel.yAxis.logBase)
      .domain([y_min, y_max])
      .range([chartHeight, 0]);

    let domain = yScale.domain();
    let tick_values = logScaleTickValues(domain, log_base);

    let decimalsAuto = ticksUtils.getPrecision(y_min);
    let decimals = panel.yAxis.decimals || decimalsAuto;

    // Calculate scaledDecimals for log scales using tick size (as in jquery.flot.js)
    let flot_tick_size = ticksUtils.getFlotTickSize(y_min, y_max, tick_values.length, decimalsAuto);
    let scaledDecimals = ticksUtils.getScaledDecimals(decimals, flot_tick_size);
    ctrl.decimals = decimals;
    ctrl.scaledDecimals = scaledDecimals;

    data.yAxis = {
      min: y_min,
      max: y_max,

      .tickSizeInner(0 - width)
      .tickSizeOuter(0)
      .tickPadding(Y_AXIS_TICK_PADDING);

    heatmap
      .append('g')
      .attr('class', 'axis axis-y')
      .call(yAxis);

    // Calculate Y axis width first, then move axis into visible area
    let posY = margin.top;
    let posX = getYAxisWidth(heatmap) + Y_AXIS_TICK_PADDING;
    heatmap.select('.axis-y').attr('transform', 'translate(' + posX + ',' + posY + ')');

    // Set first tick as pseudo 0
    if (y_min < 1) {
      heatmap
        .select('.axis-y')
        .select('.tick text')
        .text('0');
    }

    // Remove vertical line in the right of axis labels (called domain in d3)
    heatmap
      .select('.axis-y')
      .select('.domain')
      .remove();

    // Rewrite min and max if it have been set explicitly
    y_min = panel.yAxis.min !== null ? panel.yAxis.min : y_min;
    y_max = panel.yAxis.max !== null ? panel.yAxis.max : y_max;

    // Adjust ticks after Y range widening
    tick_interval = ticksUtils.tickStep(y_min, y_max, ticks);
