Highcharts: stacked bar charts tooltip enable shared and keep display arrow - highcharts

Question

When I enable tooltip.shared = true, The arrow will disappear like screen shot.
tooltip: {
shared: true
},
I want to keep arrow just like tooltip.shared = false
tooltip: {
shared: false
},

Does anyone know to accomplish this?
Thank you!

Answer 1

You can prevent from skipping the tooltip anchor in case tooltip is shared by wrapping move function. More about wrapping can be here: https://www.highcharts.com/docs/extending-highcharts/extending-highcharts. Take a look at the example below.

Answer 2

You can use tooltip.formatter with some css to achieve nearly required behavior but not exactly same when shared: false .
$(document).ready(function() {
$('#container').highcharts({
chart: {
//type: 'column'
type: 'bar'
},
title: {
text: 'Stacked column chart'
},
xAxis: {
categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas']
},
yAxis: {
min: 0,
title: {
text: 'Total fruit consumption'
},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold',
color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'
}
}
},
legend: {
align: 'right',
x: -100,
verticalAlign: 'top',
y: 20,
floating: true,
backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColorSolid) || 'white',
borderColor: '#CCC',
borderWidth: 1,
shadow: false
},
tooltip: {
shared: true,
useHTML: true,
backgroundColor: null,
borderWidth: 0,
formatter: function() {
//console.log(this.points)
var points = this.points;
var pointsLength = points.length;
var tooltipMarkup = pointsLength ? '<div class="callout right" >' + points[0].key + '<br/>' : '';
var index;
var y_value;
for (index = 0; index < pointsLength; index += 1) {
y_value = (points[index].y);
tooltipMarkup += '<span style="color:' + points[index].series.color + '">\u25CF</span> ' + points[index].series.name + ': <b>' + y_value + ' </b><br/>';
}
return tooltipMarkup + '</div>';
},
/*//you can use bellow code to adjust position
positioner: function(boxWidth, boxHeight, point) {
return {x:point.plotX,y:point.plotY};
}*/
},
plotOptions: {
series: {
stacking: 'normal',
dataLabels: {
enabled: true,
color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || '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]
}]
});
});
div.callout {
background-color: rgba(247, 247, 247, 0.85);
background-image: -moz-linear-gradient(top, rgba(247, 247, 247, 0.85), rgba(247, 247, 247, 0.85));
position: relative;
color: #000;
padding: 5px;
border-radius: 3px;
box-shadow: 0px 0px 20px #444;
}
.callout::before {
content: "";
width: 0px;
height: 0px;
border: 0.8em solid transparent;
position: absolute;
}
.callout.right::before {
left: -20px;
top: 35%;
border-right: 10px solid rgba(247, 247, 247, 0.85);
}
