highchart stacked bar chat add series dynamically - highcharts

below is my code for the stacked bar chart, It sets the values Y-axis wise instead of X-axis wise, data [5,3] should be shown in x-axis in one row and [2,2] in another x-axis point, but plotting [5,3] and [2,2]
function barChartObject() {
return jQuery.extend(true, {}, Highcharts.setOptions({
chart: {
type: 'bar',
marginTop: 10,
marginBottom: 10,
marginLeft: 50,
marginRight: 2,
width: 500
},
xAxis: {
categories: ['Apples', 'Bananas']
},
yAxis: {
min: 0,
},
legend: {
reversed: true
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
}
},
series: {
stacking: 'normal'
}
}
}));
}
function addBarSeries(chart, chartData) {
_.each(chart.series, function(s) {
s.remove();
});
chart.options.legend.enabled = false;
var series = [{
name: 'John',
data: [5, 3]
}, {
name: 'Jane',
data: [2, 2]
}];
_.each(series, function(s) {
chart.addSeries(s, false);
});
chart.redraw();
}

data [5,3] should be shown in x-axis in
one row and [2,2] in another x-axis point, but plotting [5,3] and
[2,2]
Nope, it renders as it should be. Notice that your series has defined two points, like [{x: 0, y: 2}, {x: 1, y: 2}], which are clearly visible on the chart.
If you want to have those two values in one row of the xAxis, you will need to change your data into this format:
series: [{
name: 'John',
data: [2, 3]
}, {
name: 'Jane',
data: [2, 5]
}]

Highcharts stacked column is cut off

The first stack of my column chart is not fully visible.
The only solution I found was to add a max value on the y-axis.
Bu that is not an ideal solution because the max remains even when I disable a series by clicking on it in the legend.
Here is an JSFiddle example.
{
chart:{
type: 'column'
},
plotOptions: {
column: {
stacking:"normal",
grouping: false
}
},
yAxis: {
title: {
text: ""
},
labels: {
},
allowDecimals:true,
gridLineColor:"#DDDDDD",
endOnTick:false,
max:null
},
xAxis:{
type: "datetime",
min:1609459200000,
softMax:1638316800000,
dateTimeLabelFormats: {month:"%b",year:"%Y"},
labels: {y:20},
title:{text:null},
gridLineColor:"#DDDDDD"
},
series:[{
name:"Solar power",
data:[{
x:1609455600000,y:40.328},{x:1612134000000,y:108.824},{x:1614553200000,y:58.224}],
color: "rgba(255, 174, 1, 1)",
id:"del-solarPhotovoltaic"
},
{
name:"Delivered Electricity",
data:[{x:1609455600000,y:327.583405},{x:1612134000000,y:238.927913},{x:1614553200000,y:54.12531}],
color:"rgba(96, 189, 104, 1)",
id:"del-electricity"
},
{
name:"Natural gas",
data:[{x:1609455600000,y:4073.892843},{x:1612134000000,y:2768.81114}],
color:"rgba(93, 165, 218, 1)",
id:"del-naturalGas"
},
{
name:"Exported Electricity",
data:[{x:1609455600000,y:-19.093318},{x:1612134000000,y:-68.414876},{x:1614553200000,y:-37.718392,}],
color:"rgba(96, 189, 104, 1)",
id:"exp-electricity"
}]
}
This happens because your x-axis min value: 1609459200000 is greater than the first data point x value: 1609455600000 and Highcharts doesn't take into account the first column when calculating y-axis extremes (treated as if it were outside the chart).
Similar situation presented here: http://jsfiddle.net/BlackLabel/b1oucLne/
xAxis: {
min: 4,
max: 40
},
series: [{
type: 'column',
data: [{
x: 2,
y: 4073.892843
}, {
x: 6,
y: 2768.81114
}]
}]
As a solution reduce or remove xAxis.min property.

Highcharts hide empty bars of categories for multiples series

I'm trying to implement a chart with different series but each series will have a value for different categories independently.
What I want to have:
What I have today:
With the following code:
document.addEventListener('DOMContentLoaded', function () {
Highcharts.chart('container', {
chart: {
type: 'column'
},
title: {
text: 'Fruit Consumption'
},
xAxis: {
categories: ['a1', 't1', 't2', 'l1', 'l2', 'p1']
},
yAxis: {
title: {
text: 'Fruit eaten'
}
},
series: [{
name: 'a',
data: [267]
},{
name: 't',
data: [0, 21, 400]
},{
name: 'l',
data: [0, 0, 0, 600, 242]
},{
name: 'p',
data: [0, 0, 0, 0, 0, 1000]
}],
});
});
There is free space between bars because series has 0 as values for some category.
I just want to have a "nice" chart with all columns one by one.
Maybe, it's a different way to configure series and categories...
Disable grouping:
plotOptions: {
series: {
grouping: false
}
}

Highcharts polar label textoverflow

When trying to configure a polar chart in highcharts 7.2.0 I am unable to configure the chart to always show labels on the xAxis. When the chart is not a polar chart then configuration property of xAxis.labels.styles.textOverflow = 'none' works correctly. The jsfiddle below shows that labels on the xAxis will automatically be removed if they collide with another label. I am looking to configure the polar chart to do the same thing as the line chart. When chart.polar: true is removed you can see the line chart with labels that overlap each other.
https://jsfiddle.net/y6xor7ac/3/
Highcharts.chart('container', {
chart: {
// comment this line to show line graph working correctly
polar: true
},
title: {
text: 'Highcharts Polar Chart'
},
subtitle: {
text: 'Also known as Radar Chart'
},
pane: {
startAngle: 0,
endAngle: 360
},
xAxis: {
tickInterval: 45,
min: 0,
max: 360,
overflow: 'allow',
labels: {
style: {
textOverflow: 'none'
},
format: '{value}° super long text to make it overlap super long text to make it overlap super long text to make it overlap '
}
},
yAxis: {
min: 0,
overflow: 'allow',
stackLabels: {
allowOverlap: true
}
},
plotOptions: {
series: {
pointStart: 0,
pointInterval: 45
},
column: {
pointPadding: 0,
groupPadding: 0
}
},
series: [{
type: 'column',
name: 'Column',
data: [8, 7, 6, 5, 4, 3, 2, 1],
pointPlacement: 'between'
}, {
type: 'line',
name: 'Line',
data: [1, 2, 3, 4, 5, 6, 7, 8]
}, {
type: 'area',
name: 'Area',
data: [1, 8, 2, 7, 3, 6, 4, 5]
}]
});
You can use internal allowOverlap property:
xAxis: {
...
labels: {
allowOverlap: true,
...
}
},

Round off the area points in Highcharts Polar

Is there is a way to round off the area points and make them less pointed when used in the polar chart?
I have tried the 'areaspline', but with polar chart it's not quite right, as you can see here:
http://jsfiddle.net/qwbu6r3t/2/
Highcharts.chart('container', {
chart: {
polar: true
},
title: {
text: 'Highcharts Polar Chart'
},
pane: {
startAngle: 0,
endAngle: 360
},
xAxis: {
tickInterval: 45,
min: 0,
max: 360,
labels: {
formatter: function () {
return this.value + '°';
}
}
},
yAxis: {
min: 0
},
plotOptions: {
series: {
pointStart: 0,
pointInterval: 45
}
},
series: [{
type: 'areaspline',
name: 'Area spline',
data: [1, 2, 3, 4, 5, 6, 7, 8]
}, {
type: 'area',
name: 'Area',
data: [1, 8, 2, 7, 3, 6, 4, 5]
}]
});
EDIT
What I need
You can override highcharts Highcharts.seriesTypes.areaSpline.prototype.getPointSpline with same method but with changed smoothing parameter. (Default 1.5)
...
var smoothing = 3, // 1 means control points midway between points, 2 means 1/3 from the point, 3 is 1/4 etc
...
Live example:

just change area to areaspline would do what you want i think so

Displaying count on bar and percentage on Y-axis of cloumn chart using Highcharts

My series data and column chart look like this.
series data array values are the count which i need to display on the top of bars and series percentwithingroupvalues array data as in the fiddle should be my Y-axis data.
How to acheive this? Below is my data
series: [{
name: 'John',
data: [5, 3, 4, 7, 2],
/*Percentage is calculated as
Below values are random
(5)*100/(5+2+3)
*/
percentwithingroupvalues:[20,20,20,20,20]
}, {
name: 'Jane',
data: [2, 2, 3, 2, 1],
percentwithingroupvalues:[20,20,20,20,20]
}, {
name: 'Joe',
data: [3, 4, 4, 2, 5],
percentwithingroupvalues:[20,20,20,20,20]
}]
You need to set for each point object { }, instead of value y , see: http://jsfiddle.net/tRKad/3/
plotOptions: {
column: {
dataLabels: {
enabled: true,
formatter: function () {
return this.point.custom;
}
}
}
},
series: [{
name: 'John',
data: [{
custom: 5,
y: 20
}, {
custom: 3,
y: 15
}, {
custom: 4,
y: 11
}, {
custom: 22,
y: 7
}, {
custom: 33,
y: 2
}],
}]
