How to correspond tooltip title with the legends at the bottom in Highcharts?

The 3 labels that I have on the horizontal stacked bar, the data flow for label 1 is different than label 2 and 3. Compare to label 2 and 3, label 1 colors flow is different.
When I hover over label 1 bars, I see correct title getting displayed in the tooltip that matches with the legend at the bottom:
However, when I hover the bar for label 2 and 3, which in this dark red, I still see "Strongly Agree" showing up in the tooltip, whereas it should have been "Strongly Disagree" if go by the legends at the bottom:
Is this something that is managable to fix it in higcharts? If so, can someone please help me how I would fix the tooltip title for label 2 and 3?

I made 2 changes to the fiddle
Change tooltip
Change to show the series name instead of referencing a list
formatter: function () {
return '<b>'+ this.series.name + '</b><br/>' + 'Response Rate: ' + (100*this.point.y).toFixed(2) + '\%';
}
Change setData()
Remove all the "colors" from setData to ensure consistency across categories.
series.setData([
{
name: tooltip_titles[s],
//color: colors[s],
y: dept_data["102"][4-s]
},
{
name: tooltip_titles[s],
// color: colors[Math.abs(s - 4)],
y: dept_data["104"][4-s]
},
{
name: tooltip_titles[s],
// color: colors[Math.abs(s - 4)],
y: dept_data["105"][4-s]
}]);
Here's the result:

How to show multiple graphs in drilldown (highcharts)?

NET MVC Project, where I use Highcharts. In my charts i have columns and a spline.
I have already implemented drilldown for my chart and it works perfectly, but only for the columns. On the first level the columns and the spline is shown, but when I trigger drilldown only the columns are shown. data2 should be the spline.
var mychart = Highcharts.chart('container', {
chart: {
zoomType: 'xy',
spacingBottom: 40,
spacingTop: 40,
events: {
// DRILLDOWN
drilldown: function (e) {
//Some variables id, func
$.getJSON(`/Home/GetDataForMinuteDrilldown?id=${id}&function=${func}`, function (data) {
console.log(data);
var durationArrMinutes = data.map(function (item) {
return item['minuteavg'];
});
var errorArrayMinutes = data.map(function (item) {
return item['errorsperminute']
});
var minuteArray = data.map(function (item) {
return {
name: drill + ":" + item['minute'],
y: item['minuteavg'],
drilldown: item['minute']
};
});
data2 = {
name: 'Errors per Minute',
type: 'spline',
data: errorArrayMinutes,
tooltip: {
valueSuffix: ' '
}
}
data = {
name: 'Average Duration per Minute',
type: 'column',
yAxis: 1,
data: minuteArray,
tooltip: {
valueSuffix: ' ms'
},
data2 //I think this is the error, but I i know no solution
}
console.log('Data:')
console.log(data);
mychart.hideLoading();
mychart.addSeriesAsDrilldown(e.point, data);
});
}
}
},
title: {
text: 'Performance and Error Analytics'
},
subtitle: {
text: 'Analytics of: ' + func
},
xAxis: [{
type: 'category',
crosshair: true
}],
yAxis: [{ // Primary yAxis
labels: {
format: '{value}',
style: {
color: Highcharts.getOptions().colors[1]
}
},
title: {
text: 'Errors',
style: {
color: Highcharts.getOptions().colors[2]
}
}
}, { // Secondary yAxis
title: {
text: 'Duration in ms',
style: {

}
},
labels: {

},

},
series: [{
name: 'Average Duration per Hour',
type: 'column',
yAxis: 1,
data: durationPerHourArray,
tooltip: {
valueSuffix: ' ms'
}
}, {
name: 'Errors',
type: 'spline',
data: errorArray,
tooltip: {
valueSuffix: ' '
}
}],
drilldown: {
activeAxisLabelStyle: {
textDecoration: 'none',
fontStyle: 'normal',
color: 'black'
},
series: []
}
});

The addSeriesAsDrilldown method allows to add only one series to drilldown. From source code:
Chart.prototype.addSeriesAsDrilldown = function (point, options) {
this.addSingleSeriesAsDrilldown(point, options);
this.applyDrilldown();
};
Instad of addSeriesAsDrilldown, you can use internal addSingleSeriesAsDrilldown method to add both series and call applyDrilldown:
mychart.addSingleSeriesAsDrilldown(e.point, data);
mychart.addSingleSeriesAsDrilldown(e.point, data2);
mychart.applyDrilldown();

spline is not plotting after drilldown - HighCharts

I am working with highCharts drilldown. My graph is plotting proper before drilldown. The column and spline is properly getting plot according to X-axis and Y-axis in graph but after drilldown the graph spline is not draw according to Y-axis. I want to plot spline as like before drilldown.
Here is my html
<script src="http://code.highcharts.com/highcharts.js"></script>
<script src="http://code.highcharts.com/modules/drilldown.js"></script>
<div id="container" style="min-width: 310px; height: 400px; margin: 0 auto"></div>

if (!e.seriesOptions) {
var chart = this,

drilldown: {

});

On drilldown events you are creating new spline series and you don't specify y axis for them - by default they will be scaled with the use of the first y axis.
Specify a correct yAxis (should be 1 in your example) for the series and the spline will be drawn as you expect.
drilldownsLines = {
'2015':{
type: 'spline',
name: '2015',
data: [
['Q4-2015',11.45]
],
yAxis: 1
},
'2016':{
type: 'spline',
name: '2016',
yAxis: 1,
data: [
['Q2-2016',11.2],
['Q3-2016',11.5]
]
}
},

Legend in Highcharts should not pick up colours specified in series data

My code is as follows :
var options = {
chart: {
type: 'column',
events: {
click: $scope.goToPath(link)
}
},
title: {
text: ""
},
xAxis: {
categories: ['You', 'Average', 'Top Quartile'],
labels: {
style: {
fontSize: '14px',
color: 'grey'
}
}
},
yAxis: {
title: {
text: ''
}
},
plotOptions: {
column: {
colorByPoint: true,
dataLabels: {
enabled: true,
color: '#000000',
style: {
fontWeight: 'bold'
},
formatter: $scope.getBarValues()
}
}
},
series: [{
showInLegend: true,
name: 'Planning Sites',
data: metric1["chart_numbers"],
colors: ['#3399CC', '#CCCC33', '#686868']
}, {
showInLegend: true,
name: 'Build Out And Implementation',
data: metric2["chart_numbers"],
colors: ['#99CBE5', '#E4E599', '#BFBFBF']
}
]
}
Here, I want to customize the legend shown so that it does not use the colors specified in the colors array of each of the series element. How can I do that?
I want the legend as follows :
Black color - Planning
Grey color - Build Out
Here is the jsFiddle : http://jsfiddle.net/Kc55H/

For each series you can set also color, see: http://jsfiddle.net/Kc55H/1/

set different colors for each column in highcharts

I need to set different colors for each column in Highcharts graph dynamically. My Highcharts graph is:
options = {
chart: {
renderTo: 'chart',
type: 'column',
width: 450
},
title: {
text: 'A glance overview at your contest’s status'
},
xAxis: {
categories: ['Approved Photos', 'Pending Approval Photos',
'Votes', 'Entrants'],
labels: {
//rotation: -45,
style: {
font: 'normal 9px Verdana, sans-serif, arial'
}
}
},
yAxis: {
allowDecimals: false,
min: 0,
title: {
text: 'Amount'
}
},
legend: {
enabled: false
},
series: []
};
series = {
name: "Amount",
data: [],
dataLabels: {
enabled: true,
color: '#000000',
align: 'right',
x: -10,
y: 20,
formatter: function () {
return this.y;
},
style: {
font: 'normal 13px Verdana, sans-serif'
}
}
};
The data is set this way:
for (var i in Data) {
if (parseInt(Data[i]) != 0) {
series.data.push(parseInt(Data[i]));
} else {
series.data.push(null);
}
}
options.series.push(series);
chart = new Highcharts.Chart(options);
How can I dynamically set different colors for each data point in this loop?

Here is another solution with the latest version of Highcharts (currently 3.0).
Set the colorByPoint option to true and define the color sequence that you want.
options = {
chart: {...},
plotOptions: {
column: {
colorByPoint: true
}
},
colors: [
'#ff0000',
'#00ff00',
'#0000ff'
]
}
Here is an example based upon Highcharts Column with rotated labels demo

When you add the value to the series.data you can also set the color using the point options e.g
series.data.push({ y: parseInt(Data[i]), color: '#FF0000' });
For more details about the point options see https://api.highcharts.com/class-reference/Highcharts.Point#color

Try either of these approaches:
Approach 1:
Highcharts.setOptions({ colors: ['#3B97B2', '#67BC42', '#FF56DE', '#E6D605', '#BC36FE'] });
Approach 2:
var colors = ['#3B97B2', '#67BC42', '#FF56DE', '#E6D605', '#BC36FE', '#000'];
$('#bar_chart').highcharts({
chart: {
type: 'column'
},
title: {
text: ''
},
subtitle: {
text: ''
},
xAxis: {
type: 'category'
},
yAxis: {
title: {
text: ''
}
},
legend: {
enabled: false
},
plotOptions: {
series: {
borderWidth: 0,
dataLabels: {
enabled: false
}
}
},
series: [{
name: '',
colorByPoint: true,
data: [{
name: 'Blue',
y: 5.78,
color: colors[0]
}, {
name: 'Green',
y: 5.19,
color: colors[1]
}, {
name: 'Pink',
y: 32.11,
color: colors[2]
}, {
name: 'Yellow',
y: 10.04,
color: colors[3]
}, {
name: 'Purple',
y: 19.33,
color: colors[4]
}]
}]
});

i had colors from API response and 2 series. second series with dynamic colors.
following is sample to set dynamic colors while series mapping.
const response = [{
'id': 1,
'name': 'Mango',
'color': '#83d8b6',
'stock': 12.0,
'demand': 28,
},
{
id ': 2,
'name': 'Banana',
'color': '#d7e900',
'stock': 12.0,
'demand': 28,
}
];
let chartData: {
categories: [],
series: []
};
chartData.categories = response.map(x => x.name);
chartData.series.push({
name: 'Series 1',
type: 'column',
data: response.map(x => x.demand)
});
chartData.series.push({
name: 'Series 2',
type: 'column',
data: response.map(x => ({
y: x.stock,
color: x.color // set color here dynamically
}))
});
console.log('chartData: ', chartData);
