Highcharts: Add multiple colors to area line chart

I am trying to create a chart like this one:
:
I have already achieved all of the features except the multi colored line of the area chart. I want to show the different gradients of the chart in different colors, thus I need multiple colors on the line.
I have already tested zones like shown here and also common plugins like this. Both do not work. The zones are applied to the area which I do not want and the plugin can only color lines OR areas but not only lines in area charts.
My current Highcharts settings look like this:
{
title: {
text: null
},
xAxis: {
crosshair: true,
labels: {
format: '{value} km'
},
title: {
text: null
},
opposite: true,
startOnTick: true,
endOnTick: false,
min: 0
},
yAxis: {
startOnTick: true,
showFirstLabel: false,
endOnTick: false,
maxPadding: 0.35,
title: {
text: null
},
min: 100,
labels: {
format: '{value} m'
}
},
plotOptions: {
dataGrouping: {
enabled: false
},
showInNavigator: true,
stacking: 'normal',
series: {
dragDrop: {
draggableY: true
},
point: {
events: {
mouseOver: (e) => {
this.chartHover.emit({
distance: e.target.x * 1000
});
},
}
},
},
area: {
dragDrop: {
draggableY: true,
dragPrecisionY: 1
}
}
},
credits: {
enabled: false
},
legend: {
enabled: false
},
chart: {
update: true,
styledMode: true,
marginBottom: 0,
marginRight: 0
},
tooltip: {
headerFormat: '',
pointFormatter: function () {
let point = this;
if (!this.series) {
return;
}
return '<span class="tooltip-area-series-' + this.series.index + '">\u25CF</span> ' + point.series.name + ': <b>' + point.y + 'm</b><br/>';
},
shared: true
},
series: [],
};
Is there an built-in solution for this?
EDIT:
I used the proposed solution by ppotaczek:
series: [{
type: 'areaspline',
id: 'areaSeries',
data: data
}, {
type: 'spline',
linkedTo: 'areaSeries',
data: data,
zoneAxis: 'x',
zones: [{
color: 'red',
value: 2
}, {
color: 'green',
value: 4
}]
}]
This works pretty good, but has some performance pitfalls when you try to add approx. more than 150 zones on desktop browsers.
There is also a small rendering issue - small gaps between the zones.
Best,
Philipp

You can add an extra spline series with zones:
series: [{
type: 'areaspline',
id: 'areaSeries',
data: data
}, {
type: 'spline',
linkedTo: 'areaSeries',
data: data,
zoneAxis: 'x',
zones: [{
color: 'red',
value: 2
}, {
color: 'green',
value: 4
}]
}]

Angularjs highchart doesn't show in IE and SAFARI

highchart doesn't show in IE and SAFARI. I try the solution from the official highchart forum, but nothing help (remove "," at the end of json, or resize page on load etc... )
I have multiple different highcharts, but here is only one for explanation. I call config function depends on chart data. My app have many different parts, and it's very hard to make working plunker. Thnx
Here is my code
function getBaseChartConfig(graphName) {
Highcharts.setOptions({
global: {
useUTC: false
}
});
var config =
{
xAxis: {
ordinal: false
},
yAxis: {
},
options: {
chart: {
zoomType: 'x',
backgroundColor: 'rgba(255, 255, 255, 1)',
polar: true,
type: 'line',
borderRadius: 5
},
legend: {
enabled: true
},
rangeSelector: {
//za postavit rucni upis date range-a
enabled: false,
inputStyle: {
color: 'black'
}
},
navigator: {
enabled: true
}
},
series: [],
title: {
text: graphName
},
useHighStocks: true
};
return config;
};
$scope.data.push(solar_voltage);
$scope.data.push(battery_voltage);
$scope.data.push(solar_current);
$scope.data.push(hybridCurrent);
$scope.chartConfig1 = getChartConfigWithYaxisPlotLines('Production');
$scope.chartConfig1.series.push({
id: 1,
name: "Solar voltage",
data: $scope.data[0],
tooltip: {
valueDecimals: 2
}
}, {
id: 2,
name: "Battery voltage",
data: $scope.data[1],
tooltip: {
valueDecimals: 2
}
}, {
id: 3,
name: "Solar current",
data: $scope.data[2],
tooltip: {
valueDecimals: 2
}
}, {
id: 4,
name: "Hybrid current",
data: $scope.data[3],
tooltip: {
valueDecimals: 2
}
}
);
function getChartConfigWithYaxisPlotLines(graphName) {
var baseChartConfig = getBaseChartConfig(graphName);
baseChartConfig.yAxis.plotLines = [{
color: '#FF0000',
width: 1,
value: 11.50,
label: {text: '11.50'}
}];
return baseChartConfig;
}
Here is image how this look in safari or IE
And here is in CHROME and FIREFOX
This is my json from api

How to show Day as well as Time in between the days? Multiple data on x-axis Highachrts

I have multiple data coming on each day and I was wondering how to make a graph where I see the days and when I zoom in I should see the time in between the days. I am not able to do so resulting in a graph with days getting duplicated or triplicated as per the number of data points.
Before Zooming:-
After Zoom :-
I would like not to have duplicate Day names rather time in between them.
My Highcharts-ng configuration json object is as follows:-
{
options: {
chart: {
type: 'line',
zoomType: 'xy',
animation: true
},
colors:['#2C91DE','#165A8E'],
plotOptions: {
line:{
marker:{
symbol:'circle'
}
},
series: {
lineWidth: 3,
marker: {
fillColor: 'white',
lineWidth: 1,
lineColor: null,
enabled: true,
radius: 5
}
}
},
tooltip: {
shared: true,
crosshairs: true,
followPointer: true
}
},
title: {
text: ''
},
loading: false,
xAxis: {
type: 'datetime',
title: {
text: 'Date/Time'
},
dataTimeLabelFormats:{
day:'%a',
week:'%a',
},
labels: {
format: '{value:%a}'
}
},
series: [{
pointIntervalUnit: 'hourly'
}],
yAxis: {
title: {
text: ''
}
},
size: {
height: 500
}
}

Highcharts - Show tooltip onClick instead of hover

I have tried the solution at https://stackoverflow.com/a/24206104/5653279 but to no avail as my Highcharts consist of 2 series of data.
Following the above solution returns me the error
Uncaught TypeError: Cannot read property 'category' of undefined
$(function () {
$('#container').highcharts({
chart: {
type: 'spline',
zoomType: 'xy',
events: {
load: function(){
this.myTooltip = new Highcharts.Tooltip(this, this.options.tooltip);
}
}
},
tooltip: {
enabled: false,
headerFormat: '<b>{point.x: %A, %b %e at %I:%M %p}</b><br>',
shared: true,
borderRadius: 10,
crosshairs: [true, false] //x,y
},
plotOptions: {
series: {
stickyTracking: false,
events: {
click: function(evt) {
this.chart.myTooltip.refresh(evt.point, evt);
},
mouseOut: function() {
this.chart.myTooltip.hide();
}
}
}
},
title: {
text: 'Glucose/Carbohydrate'
},
subtitle: {
text: 'Ratio between Glucose and Glucose'
},
xAxis: {
type: 'datetime',
dateTimeLabelFormats: {
month: '%e/%b',
},
title: {
text: 'Date'
}
},
yAxis: [{ // Glucose yAxis
labels: {
format: '{value}mmol/L',
style: {
color: Highcharts.getOptions().colors[0]
}
},
title: {
text: 'Glucose',
style: {
color: Highcharts.getOptions().colors[0]
}
}
}, { // Carbohydrate yAxis
title: {
text: 'Carbohydrate',
style: {
color: Highcharts.getOptions().colors[1]
}
},
labels: {
style: {
color: Highcharts.getOptions().colors[1]
}
},
opposite: true
}],
series: [{
name: 'Glucose',
data: glucose,
marker: {
enabled: true
},
tooltip: {
valueSuffix: ' mmol/L'
}
},{
name: 'Carbohydrate',
data: carbohydrate,
dashStyle: 'shortdot',
yAxis: 1,
marker: {
enabled: true
}
}
]}
);
});
However, the error would be "solved" if I edit plotOptions as seen.
plotOptions: {
series: [{
stickyTracking: false,
events: {
click: function(evt) {
this.chart.myTooltip.refresh(evt.point, evt);
},
mouseOut: function() {
this.chart.myTooltip.hide();
}
}
},
{
stickyTracking: false,
events: {
click: function(evt) {
this.chart.myTooltip.refresh(evt.point, evt);
},
mouseOut: function() {
this.chart.myTooltip.hide();
}
}
}]
},
But still, the tooltip does not show when I clicked on any point.

Solved the issue!
Just changed
this.chart.myTooltip.refresh(evt.point, evt);
to
this.chart.myTooltip.refresh([evt.point], evt);
But the only limitation to this fix is if there's multiple series (e.g. Line A and B) and the data of both series falls on the same X-Axis (e.g. on the same date), clicking on it will only show the tooltip of that particular series's data (if I click on series A's data, the tooltip only shows A's data without B, even though they are sharing the same X-Axis).

highchart print chart/chart context menu un-clickable

I use highchart everything works good except for the chart print button is not click-able, below are my highchart implementation and reference image. Any ideas, clues, suggestions, recommendations, help?
$('#chart_portfolio').highcharts({

},

text: false,
x: -20 //center
},

},
plotLines: [{

}]
},
tooltip: {

Simply set higher zIndex for that button: http://jsfiddle.net/9P5fC/488/
exporting: {
buttons: {
contextButton: {
theme: {
zIndex: 100
}
}
}
}
