Highcharts条形图中的阴影

Question

I want to give 5 px shadow in right side of the bar. Is it possible?

You should use the Renderer which allows to add custom paths in chart. Knowing that, catch the load event and iterate on each series point, adding line in right side.

chart: {
  type: 'column',
  events: {
    load: function() {
      var chart = this,
        series = chart.series,
        each = Highcharts.each,
        r = chart.renderer,
        borderWidth  = 2,
        x,y;

      each(series, function(s, i) {
        each(s.data, function(p, j) {
                        x = p.plotX + chart.plotLeft + (p.pointWidth / 2);
                        y = p.plotY + chart.plotTop + borderWidth;

          r.path(['M', x, y, 'L', x, y + p.shapeArgs.height])
          .attr({
            zIndex: 10,
            'stroke-width': borderWidth,
            'stroke': 'gray'
          })
          .add()
        });
      });
    }
  }
},
