示例1: addXAxis

  function addXAxis() {
    scope.xScale = xScale = d3.scaleTime()
      .domain([timeRange.from, timeRange.to])
      .range([0, chartWidth]);

    let ticks = chartWidth / DEFAULT_X_TICK_SIZE_PX;
    let grafanaTimeFormatter = grafanaTimeFormat(ticks, timeRange.from, timeRange.to);
    let timeFormat;
    let dashboardTimeZone = ctrl.dashboard.getTimezone();
    if (dashboardTimeZone === 'utc') {
      timeFormat = d3.utcFormat(grafanaTimeFormatter);
    } else {
      timeFormat = d3.timeFormat(grafanaTimeFormatter);
    }

    let xAxis = d3.axisBottom(xScale)
      .ticks(ticks)
      .tickFormat(timeFormat)
      .tickPadding(X_AXIS_TICK_PADDING)
      .tickSize(chartHeight);

    let posY = margin.top;
    let posX = yAxisWidth;
    heatmap.append("g")
      .attr("class", "axis axis-x")
      .attr("transform", "translate(" + posX + "," + posY + ")")
      .call(xAxis);

    // Remove horizontal line in the top of axis labels (called domain in d3)
    heatmap.select(".axis-x").select(".domain").remove();
  }

示例2: constructor

  constructor(rootElt: AnySvgSelection, bounds: ChartBounds) {
    this.bounds = bounds;

    this.xScale = d3.scaleTime().range(
      [bounds.axisSize + bounds.margin,
       bounds.width - bounds.margin]);
    this.yScale = d3.scaleLinear().range(
      [bounds.height - bounds.axisSize - bounds.margin,
       bounds.margin]);

    this.yAxis = d3.axisLeft<number>(this.yScale)
      .ticks(3);
    this.xAxis = d3.axisBottom<Date>(this.xScale)
      .ticks(d3.timeDay.every(1))
      .tickFormat(d3.timeFormat("%b %d"));

    this.lineSpec = d3.line<DataPoint>()
      .x((d: DataPoint) => this.xScale(new Date(d.unix_seconds * 1000)))
      .y((d: DataPoint) => this.yScale(d.temperature));

    this.rootElt = rootElt;

    this.precipBar = new IntensityBand<DataPoint>(
      (d: DataPoint) => d.precipitation_chance,
      intensity.blue,
      {
        width: this.bounds.width - this.bounds.axisSize - 2 * this.bounds.margin,
        height: 3,
        xPos: this.bounds.axisSize + this.bounds.margin,
        yPos: this.bounds.height - this.bounds.axisSize - this.bounds.margin,
      },
      this.rootElt,
      "precipBar");

    this.cloudsBar = new IntensityBand<DataPoint>(
      (d: DataPoint) => d.clouds,
      intensity.gray,
      {
        width: this.bounds.width - this.bounds.axisSize - 2 * this.bounds.margin,
        height: 3,
        xPos: this.bounds.axisSize + this.bounds.margin,
        yPos: this.bounds.height - this.bounds.axisSize - this.bounds.margin + 3,
      },
      this.rootElt,
