As soon as I scroll using x axis and hover over any bar the tooltip location comes at the end of the chart rather than above the bar.
const chart = Highcharts.ganttChart('container', {

currnet code status - currently I am showing tooltip on series only.
expected - I want to show the tooltip on the locations where the yaxis and xaxis graph lines cross.
Add Plugin 'angular2-highcharts'
add code in ionViewDidLoad()
var chart = Highcharts.mapChart('container', {
chart: {
map: 'custom/europe',
spacingBottom: 20
},
title: {
text: 'Europe time zones'
},
legend: {

plotOptions: {
map: {
allAreas: false,

},
// Only show dataLabels for areas with high label rank
format: null,
formatter: function () {
if (this.point.properties && this.point.properties.labelrank.toString() < 5) {
return this.point.properties['iso-a2'];
}

I am using HighCharts to ploot some graph. I want my y-aixs to range between -1 to +1. When i set max=1 and min=-1 for y-axis, it does not work. Is there another way of implementing this. Below is the my code example.
$(opts.containerSelector).find('.chart-container').highcharts({
chart: {
events: {
load: loadLegendSelection
},
},
plotOptions: {
area: {
fillOpacity: 0.7
},
spline: {
marker: {
radius: 3
}
},
series: {
events: {
legendItemClick: storeLegendSelection
}
}
},
legend: {
},
loading: {
labelStyle: { "position": "relative", "top": "45%", "font-weight": "300", "color": "#29303a", "font-size": "22px" }
},
xAxis: {
gridLineDashStyle: 'dash',
gridLineColor: '#c2dce6',
gridLineWidth: 1,
min: minDate,
max: maxDate,
type: 'datetime',
labels: {
formatter: function() {
return formatTimestampTime(this.value);
}
},
events : {
afterSetExtremes : afterSetExtremes.bind(this, opts)
},
minRange: 3600 // one minute
},
yAxis: {
max: 1,
min: -1,
endOnTick: false,
gridLineDashStyle: 'dash',
gridLineColor: '#c2dce6',
gridLineWidth: 1,
labels: {
formatter: function() {
return formatMegawatts(this.value);
}
},
showFirstLabel: false,
title: ''
},
series: convertedData,
exporting: {
enabled: false
},
credits: {
enabled: false
},
tooltip: {
formatter:
function() {
return '<b>' + formatTimestampDateTimeWithSeconds(this.x) + '</b><br>' + formatMegawatts(this.y) + ' ('+ this.series.name + ')';
}
}
});
you can try setting min and max as given below.
yAxis: [{
max:1,
min: -1,
allowDecimals: false,
endOnTick: false,
gridLineWidth: 0,
labels: {
style: {
color: '#767676'
}
},
offset: -10,
title: {
text: 'Inv ' + val_qty,
"textAlign": 'top',
"rotation": 0,
x: 60,
y: yaxisVal,
style: {
color: '#767676',
fontWeight: 'bold'
}
}
}, {
allowDecimals: false,
min: 0,
endOnTick: false,
gridLineWidth: 0,
title: {
text: y2axisname,
"textAlign": 'top',
"rotation": 0,
x: -75,
y: yaxisVal,
style: {
color: '#767676',
fontWeight: 'bold'
}
},
offset: -10,
labels: {
format: '{value}',
style: {
color: '#767676'
}
},
opposite: true
}],
I have following code:
$(function () {
$('#container').highcharts({
chart: {
type: 'spline',
zoomType: 'xy',
borderRadius: 20,
borderWidth: 2,
},
credits: {

},
exporting: {

return this.value.toString().substring(0, 6);
},
rotation: 0.1,

step: 20,
enabled: true
},
style: {
fontSize: '8px'
}
},
yAxis: {
title: {
text: 'CO2'
},
labels: {
formatter: function() {
return this.value +'°'
}
}
},
legend: {
enabled: false
},
tooltip: {
// crosshairs: true,
shared: true,

plotOptions: {
spline: {

lineWidth: 1
}
}
},
series: [{
name: "CR3000Tower",
data: chartData,
marker: {
enabled: false
}
} ]
});
});
It is producing the following output:
I want to truncate the tooltipe value after 2 decimal point. So that the tooltip value will be 414.26 instead of the long value. Any help please. Thanks.
Set valueDecimals, see docs.
I have created a wind rose type chart using highcharts, and something like a label
that needs to be removed
I tried using: { lables: { enabled: false } } and also tried using
showFirstLabel and showLastLabel
But it didn't work for me :(
Here is how i created the wind rose chart:
wind_rose_chart = Highcharts.data({
table: 'roulette_windrose',
startRow: 1,
endRow: 38,
endColumn: 37,
complete: function (options) {
// Create the chart
window.chart = new Highcharts.Chart(Highcharts.merge(options, {
chart: {
renderTo: 'windrose_container',
polar: true,
type: 'column',
animation: false,
backgroundColor: '#e4e6e1',
plotBackgroundImage: "/images/gallery/windrose_roulette.png",
height: 400,
width: 350,
},
colors: ['#008403',
'#E30000','#000000','#E30000',
'#000000','#E30000','#000000',
'#E30000','#000000','#E30000',
'#000000','#000000','#E30000',
'#000000','#E30000','#000000',
'#E30000','#000000','#E30000',
'#E30000','#000000','#E30000',

'#000000','#000000','#E30000',
'#000000','#E30000','#000000',
'#E30000','#000000','#E30000'],
title: {
text: 'Spots'
},
pane: {
size: '70%'
},
legend: {
enabled: false
},
xAxis: {
labels: {
enabled: false
},
showFirstLabel: false,
showLastLabel: false,
tickmarkPlacement: 'on',
lineWidth:0,
gridLineWidth: 0
},
yAxis: {
min: 0,
gridLineWidth: 0,
endOnTick: false,
showLastLabel: false,
showFirstLabel: false,
labels: {
formatter: function () {
return this.value;
}
}
},
tooltip: {
formatter: function() {
return this.y;
}
},
plotOptions: {
series: {
stacking: 'normal',
shadow: false,
groupPadding: 0,
pointPlacement: 'on',
}
},
navigation: {
buttonOptions: {
enabled: true
}
},
exporting: {
enabled: true
},
credits: {
enabled: false
}
}));
}
});
following code is working:
yAxis: {
...
labels: {
enabled: false
}
}
