可以在Highcharts中使用鼠标进行缩放吗？

Question

是否可以使用鼠标放大高级图表,例如Google地球？

有代码可以吗？

Answer 1

通过在Highcharts中包含Highmaps作为模块,可以实现Highcharts鼠标滚轮缩放.

$(function() {
  $.getJSON('https://www.highcharts.com/samples/data/jsonp.php?filename=usdeur.json&callback=?', function(data) {

    $('#container').highcharts({
      chart: {
        panning: true
      },
      mapNavigation: {
        enabled: true,
        enableButtons: false
      },
      title: {
        text: 'USD to EUR exchange rate over time'
      },
      subtitle: {
        text: document.ontouchstart === undefined ?
          'Click and drag in the plot area to zoom in' : 'Pinch the chart to zoom in'
      },
      xAxis: {
        type: 'datetime'
      },
      yAxis: {
        title: {
          text: 'Exchange rate'
        }
      },
      legend: {
        enabled: false
      },
      plotOptions: {
        area: {
          fillColor: {
            linearGradient: {
              x1: 0,
              y1: 0,
              x2: 0,
              y2: 1
            },
            stops: [
              [0, Highcharts.getOptions().colors[0]],
              [1, Highcharts.Color(Highcharts.getOptions().colors[0]).setOpacity(0).get('rgba')]
            ]
          },
          marker: {
            radius: 2
          },
          lineWidth: 1,
          states: {
            hover: {
              lineWidth: 1
            }
          },
          threshold: null
        }
      },

      series: [{
        type: 'area',
        name: 'USD to EUR',
        data: data
      }]
    });
  });
});
