Echarts.js tooltip not showing with formatter function

Echarts.js on Angular 10 and these are my toltip options :
tooltip: {
show: true,
trigger: 'axis',
axisPointer: {
type: 'line',
lineStyle: {
color: eTheme.tooltipLineColor,
width: eTheme.tooltipLineWidth,
},
},
textStyle: {
color: eTheme.tooltipTextColor,
fontSize: 20,
fontWeight: eTheme.tooltipFontWeight,
},
position: 'top',
backgroundColor: eTheme.tooltipBg,
borderColor: eTheme.tooltipBorderColor,
borderWidth: 1,
extraCssText: eTheme.tooltipExtraCss,
formatter : (params) => {
return Math.round(parseInt(params[0].value, 10));
},
},
The problems is that with formatter my tooltip is not showing , when i delete formatter - everything is fine and tooltip is showing again.
What is wrong with formatter ?

Highcharts treemap with colouraxis updating styles

I've tried various ways of updating treemap color axis legend font size and font family
var options = {
colorAxis: {
minColor: '#FFFFFF',
maxColor: Highcharts.getOptions().colors[0],
labels: {
style: {
fontSize: '10px',
fontFamily: 'Arial'
}
}
},
series: [{
type: 'treemap',
layoutAlgorithm: 'squarified',
data: [{
name: 'A', value: 6,colorValue: 1 }, { name: 'B',value: 6,colorValue: 2 }, {
name: 'C',value: 4,colorValue: 3}, {name: 'D',value: 3,colorValue: 4 }, {
name: 'E',value: 2,colorValue: 5 }, {name: 'F',value: 2, colorValue: 6}, {
name: 'G',value: 1,colorValue: 7}] }],
title: {
text: 'Highcharts Treemap'
}
};
var chart = Highcharts.chart('container', options);
$('#update').click(function () {
chart.update({
chart:{
style: {
fontSize: '20px',
fontFamily: 'HelveticaNeue'
}
},
legend: {
itemStyle: {
fontSize: '20px',
fontFamily: 'HelveticaNeue'
}
},
colorAxis: {
labels: {
style: {
fontSize: '20px',
fontFamily: 'HelveticaNeue'
}
}}
});
chart.legend.update({
itemStyle: {
fontSize: '20px',
fontFamily: 'HelveticaNeue'
}
})
});
Please see here - http://jsfiddle.net/hsuh/t04qe2xx/8/
Style doesn't seem to be updated. Please help. Thanks

Your click event is not fired because of the difference in id.
Remove hash from button's id: <button id='update'> Update </button>
Then you can update axis via axis.update()
$('#update').click(function() {
chart.colorAxis[0].update({
labels: {
style: {
fontSize: '20px'
}
}
})
});

Highcharts - center placement of columns

I have a Highcharts column chart and I am trying to reduce the distance between each column on the X axis whilst pulling them towards the center so that the columns appear more grouped.
So for example in my example above, the red and the blue column would be much closer together and positioned towards the center.
Below is my chart configuration. The seriesData parameter is just a custom object I pass in at render.
chartConfig.js
function chartConfig(seriesData) {
return {
barColor: seriesData.color,
data: seriesData,
credits: { enabled: false },
chart: {
width: seriesData.width,
defaultSeriesType: 'column',
backgroundColor: '#EAEFF6'
},
tooltip: { enabled: false },
colorAxis: {
dataClassColor: 'category'
},
colors: [],
legend: {},
title: {
useHTML: true,
text: (seriesData.name === 'n/a' || seriesData.name === 'N/A') ? '_' : seriesData.name,
style: {
color: (seriesData.name === 'n/a' || seriesData.name === 'N/A') ? '#E9EFF4' : '#666666',
fontSize: '14px',
fontFamily: 'Roboto',
fontWeight: 'bold',
paddingTop: '10px',
lineHeight: '1em'
},
align: 'center',
x: 0,
y: 2
},
plotOptions: {
column: {
stacking: 'normal',
animation: true,
borderColor: 'grey',
borderWidth: 0
},
series: {
borderRadius: 15,
dataLabels: {
enabled: false
},
states: {
hover: {
enabled: false
}
}
}
},
yAxis: [{
max: Math.max.apply(null, seriesData.scaleValues),
min: Math.min.apply(null, seriesData.scaleValues),
title: false,
minorGridLineColor: '#FFF',
gridLineColor: '#8E8E8E',
minPadding: 0,
tickPositions: (seriesData.scalePercentageValues || null),
labels: {
formatter: function () {
if (seriesData.usePercentage) {
return `${this.value} %`;
}
return this.value;
}
}
}],
xAxis: {
lineWidth: 0,
minorGridLineWidth: 0,
lineColor: 'transparent',
minorTickLength: 0,
tickLength: 0,
categories: seriesData.elements.map((x) => { return x.name; }),
labels: {
style: {
color: '#666666',
fontSize: '12px',
fontFamily: 'Roboto'
}
}
},
series: [{
dataLabels: {
style: {
fontSize: '12px',
fontWeight: 'normal',
textShadow: 'none',
color: 'black',
fontFamily: 'Roboto',
backgroundColor: 'blue'
},
enabled: true,
formatter: function () {
if (seriesData.usePercentage) {
return `${this.y}%`;
}
return this.y;
}
},
showInLegend: false,
name: 'Fill Series',
color: '#F2F6F9',
pointWidth: 28,
animation: true,
data: seriesData.elements.map((x) => {
return { name: x.name, y: x.value, color: x.color };
}),
borderRadiusTopLeft: 10,
borderRadiusTopRight: 10,
borderColor: '#C0C0C0',
borderWidth: '1'
}]
};
}
module.exports = chartConfig;
The only solution I have tried so far is to use pointPadding and groupPadding. However this does not seem to have the desired effect.

how to add stacklabel total on Highcharts columnrange?

I'm currently working with Highcharts columnrange and I need to add stack label on top of each column/each month in order to show Total Number of Hours our Store is being Opened.. But sadly, I've tried different ways and still no joy.
Here's the current jsfiddle that I have;
http://jsfiddle.net/rds_a/0mLa0yd5/2/
Here's the code;
$(function () {
$('#container').highcharts({
data: {
table: 'summary'
},
chart: {
type: 'columnrange'
},
colors: ['black', 'orange'],
title: {
text: 'Jackstone Store'
},
yAxis: {
allowDecimals: false,
title: {
text: 'Units'
},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold',
color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'
}
}
},
plotOptions: {
columnrange: {
grouping: false,
dataLabels: {
enabled: false,
color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'white',
style: {
textShadow: '0 0 3px black'
}
}
}
}
});
});

High Charts Rendering on Internet Explorer 10

Highcharts Bar chart doesn't render well when they are put inside HTML Table. Issue is reproduced in this Fiddle. Rendering problem can be seen when opened in IE 10(works well in chrome).
var options = {
colors: ["#3ACB35", "#DE3A15", "#FF9A00", "#00B8F1"],
chart: {
renderTo: 'Chart3container',
type: 'bar',
backgroundColor: 'black',
borderColor: 'black',
borderWidth: 0,
className: 'dark-container',
plotBackgroundColor: 'black',
plotBorderColor: '#000000',
plotBorderWidth: 0
},
credits: {
enabled: false
},
title: {
text: 'Count Per Category',
style: {
color: 'white',
font: 'normal 22px "Segoe UI"'
},
align: 'left'
},
tooltip: {
backgroundColor: 'rgba(0, 0, 0, 0.75)',
style: {
color: '#F0F0F0'
}
},
categories: {
enabled: 'true'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0,
itemStyle: {
font: '9pt Segoe UI',
color: 'white'
},
itemHoverStyle: {
color: 'grey'
}
},
xAxis: {
categories: BarData.categories,
tickInterval: 1,
labels: {
enabled: true,
style: {
color: 'white'
}
},
title: {
enabled: false
},
gridLineColor: '#222222'
},
yAxis: {
title:
{
enabled: true,
text: "Document Count",
style: {
fontWeight: 'normal',
color: 'white'
}
},
labels: {
style: {
color: 'white'
}
},
gridLineColor: '#222222'
},
exporting: {
enabled: false
},
plotOptions: {
series: {
stacking: 'normal',
cursor: 'pointer'
}
},
series: []
};
options.series = BarData.bardataarray;
chart1 = new Highcharts.Chart(options);
});
When put outside table, it works well. Here is the related Fiddle.
I need table for proper alignment.

You can disable animation or use CSS styles like here:
<table>
<tr>
<td style="width:287px;height: 278px; vertical-align: top;position:relative;">
<div id="container1" style="position:absolute;height: 270px; width:287px;overflow: hidden;"></div>
</td>
</tr>
</table>
