To achieve your a 2014 result, you can use a highchart wrapper, and change how the points are drawn, like this:
(function (H) {
H.wrap(H.seriesTypes.column.prototype, 'drawPoints', function (proceed) {
$.each(this.points, function (i,point) {
let borderRadius = this.options.borderRadius;
point.shapeArgs.y -= borderRadius; //move the point down by borderRadius pixels
point.shapeArgs.height += borderRadius; //add borderRadius pixels to the total height of a point (to cover the gap)
});
proceed.apply(this, Array.prototype.slice.call(arguments, 1));
});
}(Highcharts));
(function (H) {
H.wrap(H.seriesTypes.column.prototype, 'drawPoints', function (proceed) {
let seriesIndex = this.index
$.each(this.points, function (i,point) {
point.shapeArgs.y -= seriesIndex == 0 ? 0 : 5; //if it is not the first series, then move the series down 5 pixels
point.shapeArgs.height += 5; //add 5 pixels to the total height(to cover the gap)
});
proceed.apply(this, Array.prototype.slice.call(arguments, 1));
});
}(Highcharts));
Highcharts.chart('container', {
chart: {
type: 'column',
spacingBottom: 0
},
title: {
text: ''
},
xAxis: {
categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas'],
offset: 7,
lineWidth: 0,
tickLength: 0
},
yAxis: {
min: 0,
title: {
text: ''
},
stackLabels: {
enabled: false,
style: {
fontWeight: 'bold',
color: 'gray'
}
},
visible: false
},
legend: {
align: 'center',
verticalAlign: 'bottom',
},
tooltip: {
headerFormat: '<b>{point.x}</b><br/>',
pointFormat: '{series.name}: {point.y}<br/>Total: {point.stackTotal}'
},
plotOptions: {
series: {
},
column: {
stacking: 'normal',
borderWidth: 0,
borderRadius: 5,
dataLabels: {
enabled: true,
color: 'white'
}
}
},
series: [{
name: 'John',
data: [5, 3, 4, 7, 2],
}, {
name: 'Jane',
data: [2, 2, 3, 2, 1]
}, {
name: 'Joe',
data: [3, 4, 4, 2, 5]
}]
});

If you wanted the 2015 result instead, you use the same function, like this:
(function(H) {
H.wrap(H.seriesTypes.column.prototype, 'drawPoints', function(proceed) {
let seriesIndex = this.index,
firstIndex = this.chart.series[0].index,
lastIndex = this.chart.series[this.chart.series.length - 1].index,
borderRadius = this.options.borderRadius;
this.options.borderRadius = 0; //Remove the border radius
$.each(this.points, function(i, point) {
if (seriesIndex != firstIndex && seriesIndex != lastIndex) {
point.shapeArgs.y -= borderRadius; //make sure the middle points cover the outer points
point.shapeArgs.height += borderRadius*2;
}
});
proceed.apply(this, Array.prototype.slice.call(arguments, 1));
$.each(this.points, function(i, point) {
if (seriesIndex == firstIndex || seriesIndex == lastIndex) {
point.graphic.attr({
r: borderRadius //set the borer radius to be whatever it was before to only the outer points
});
}
});
});
}(Highcharts));
I set the zIndex on the series manually, but that can be done as well. Just don't have time right now to find where to set it.
(function(H) {
H.wrap(H.seriesTypes.column.prototype, 'drawPoints', function(proceed) {
let seriesIndex = this.index,
firstIndex = this.chart.series[0].index,
lastIndex = this.chart.series[this.chart.series.length - 1].index,
borderRadius = this.options.borderRadius;
this.options.borderRadius = 0; //Remove the border radius
$.each(this.points, function(i, point) {
if (seriesIndex != firstIndex && seriesIndex != lastIndex) {
point.shapeArgs.y -= borderRadius; //make sure the middle points cover the outer points
point.shapeArgs.height += borderRadius*2;
}
});
proceed.apply(this, Array.prototype.slice.call(arguments, 1));
$.each(this.points, function(i, point) {
if (seriesIndex == firstIndex || seriesIndex == lastIndex) {
point.graphic.attr({
r: borderRadius //set the borer radius to be whatever it was before to only the outer points
});
}
});
});
}(Highcharts));

Do also note that I am manipulating the function drawPoints here, and as the docs state, it is only run once at the start. So if you start disabling/enabling series, then they will not necessarily look as you expect them to.
