Align Bar Graph with Negative Stack

https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/demo/bar-negative-stack/
xAxis: [{
categories: categories,
reversed: false,
labels: {
step: 1
}
}, { // mirror axis on right side
opposite: true,
reversed: false,
categories: categories,
linkedTo: 0,
labels: {
step: 1
}
}],
yAxis: {
title: {
text: null
},
labels: {
formatter: function () {
return Math.abs(this.value) + '%';
}
}
},
plotOptions: {
series: {
stacking: 'normal'
},
bar : {
}
},
This is the highchart graph I am using. However, I want male bars to start from left and female bars to start from right. Not from the middle.
This is what I want

It looks like just two charts placed next to each other. Check demo and code posted below.
Highcharts.chart('container1', {
chart: {
type: 'bar'
},
title: {
text: ''
},
credits: {
enabled: false
},
series: [{
data: [
439,
525,
571,
696,
970,
119,
137,
154
]
}],
});
Highcharts.chart('container2', {
chart: {
type: 'bar'
},
title: {
text: ''
},
xAxis: {
visible: false
},
yAxis: {
reversed: true
},
series: [{
color: 'red',
data: [
239,
505,
511,
596,
270,
199,
167,
224
]
}],
});
#container1 {

}
#container2 {

how to show Y axis (not it label) in jquery?

I am using highchart with jquery .I am able to show X-axis with label (Apple,pears)..But I want to show Y-axis without lable .In other words I want to show a straight line on Y-axis.
here is my code
http://jsfiddle.net/3sembmfo/118/
$(function () {
// Configure the chart
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Highcharts axis visibility'
},
xAxis: {
categories: ['Apples', 'Pears', 'Oranges', 'Peaches']
},
yAxis: {
allowDecimals: false,
title: {
text: 'Fruit'
},
visible: false
},
plotOptions: {
series: {
stacking: 'normal',
dataLabels: {
enabled: true
}
}
},
series: [{
data: [1, 3, 2, 4],
name: 'Ola'
}, {
data: [5, 4, 5, 2],
name: 'Kari'
}]
});
var yVis = false,
xVis = true;
});

This can, and should, be resolved by options:
yAxis.lineWidth - to enable the line
yAxis.title.text - to hide the title
yAxis.gridLineWidth - to disable horizontal lines,
yAxis.labels.enabled - to disable labels
Working demo: http://jsfiddle.net/BlackLabel/3sembmfo/122/
Snippet:
yAxis: {
allowDecimals: false,
title: {
text: null
},
labels: {
enabled: false
},
gridLineWidth: 0,
lineWidth: 1,
visible: true
},

Replace your y Axis code with this. http://jsfiddle.net/3sembmfo/119/. If you have any query let me know.
yAxis: {
allowDecimals: false,
labels:{
style: {
fontSize:'0px'
}
},
title: {
text: 'Fruit',
style: {
fontSize:'0px'
}
},
visible: true
},

You have to use Highcharts.SVGRenderer and add line using load event.
chart: {
type: 'column',
events: {
load: function() {
var ren = this.renderer;
ren.path(['M', 10, 10, 'L', 10, this.chartHeight * .8])
.attr({
'stroke-width': 1,
stroke: '#000'
})
.add();
}
}
},
Fiddle demo
$(function() {
// Configure the chart
$('#container').highcharts({
chart: {
type: 'column',
events: {
load: function() {
var ren = this.renderer;
ren.path(['M', 10, 10, 'L', 10, this.chartHeight * .8])
.attr({
'stroke-width': 1,
stroke: '#000'
})
.add();
}
}
},
title: {
text: 'Highcharts axis visibility'
},
xAxis: {
categories: ['Apples', 'Pears', 'Oranges', 'Peaches'],
},
yAxis: {
allowDecimals: false,
title: {
text: ''
},
labels: {
enabled: false
},
gridLineWidth: 0,
},
plotOptions: {
series: {
stacking: 'normal',
dataLabels: {
enabled: true
}
}
},
series: [{
data: [1, 3, 2, 4],
name: 'Ola'
}, {
data: [5, 4, 5, 2],
name: 'Kari'
}]
});
var yVis = false,
xVis = true;
});
#container {

Highcharts: Add point without connecting series

All,
I'm trying to allow for a user to click on a highchart between two data points and draw a line. The resulting line will calculate LARGESTVALUE-SMALLESTVALUE above the rendered line.
I'm attempting to use this example (http://jsfiddle.net/2MdEN/1/).
$(function () {
var chart;
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'scatter',
margin: [70, 50, 60, 80],
events: {
click: function(e) {
// find the clicked values and the series
var x = e.xAxis[0].value,
y = e.yAxis[0].value,
series = this.series[0];
// Add it
series.addPoint([x, y]);
}
}
},
title: {
text: 'User supplied data'
},
subtitle: {
text: 'Click the plot area to add a point. Click a point to remove it.'
},
xAxis: {
minPadding: 0.2,
maxPadding: 0.2,
maxZoom: 60
},
yAxis: {
title: {
text: 'Value'
},
minPadding: 0.2,
maxPadding: 0.2,
maxZoom: 60,
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
legend: {
enabled: false
},
exporting: {
enabled: false
},
plotOptions: {
series: {
lineWidth: 1,
point: {
events: {
'click': function() {
if (this.series.data.length > 1) this.remove();
}
}
}
}
},
series: [{
data: [[20, 20], [80, 80], null, [60, 40], [85, 60]]
}]
});
});
});
The problem is that is connects the last data point in the series to the newly added point. I'd like the points to be detached from the series to allow for lines being drawn above the generated chart.
Is there any way to accomplish this?
Thank you

You can include a second empty series in your chart config, and change which series you are adding a point to:
events: {
click: function(e) {
// find the clicked values and the series
var x = e.xAxis[0].value,
y = e.yAxis[0].value,
series = this.series[1]; <------------
// Add it
series.addPoint([x, y]);
}
}
You can also then move your point click event into the second series, if you don't want users to be able to remove points from the original data:
series: [{
data: [
[20, 20],
[80, 80], null, [60, 40],
[85, 60]
]
}, {
id: 'dummy',
color: 'rgba(204,0,0,0.9)',
point: {
events: {
'click': function() {
this.remove();
}
}
}
}]
Updated example:
http://jsfiddle.net/2MdEN/107/

I used the following
$(function () {
$('#container').highcharts({
chart: {
type: 'scatter',
margin: [70, 50, 60, 80],
events: {
click: function (e) {
var c = this.series[0].chart;
var s = this.series.length;
var x = e.xAxis[0].value;
var y = e.yAxis[0].value;
if(s == 1) {
c.addSeries('newSeries' + new Date());
c.series[1].addPoint([x, y]);
}else{
if(this.series[this.series.length-1].data.length%2 == 1) {
c.series[this.series.length-1].addPoint([x, y]);
}else{
c.addSeries('newSeries' + new Date());
c.series[this.series.length-1].addPoint([x, y]);
}
}
}
}
},
title: {
text: 'User supplied data!!!!'
},
subtitle: {
text: 'Click the plot area to add a point. Click a point to remove it.'
},
xAxis: {
gridLineWidth: 1,
minPadding: 0.2,
maxPadding: 0.2,
maxZoom: 60
},
yAxis: {
title: {
text: 'Value'
},
minPadding: 0.2,
maxPadding: 0.2,
maxZoom: 60,
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
legend: {
enabled: false
},
exporting: {
enabled: false
},
plotOptions: {
series: {
lineWidth: 1,
point: {
events: {
'click': function () {
if (this.series.data.length > 1) {
this.remove();
}
}
}
}
}
},
series: [{
data: [[20, 20], [80, 80]]
}]
});
});

How to color point in HighCharts

Hey I know that if I want to color specific point, I can do it using the fillColor attribute of current marker.
But When I hover the point, the color return to be the default color of the graph,how can I prevent such effect?
I want the point to be red in both situation(onhover event and not onhover event),
what attribute per point do I need to change for this effect to happen?
I have added a demo below, the demo act like this: when you click the canvas of the graph,a new graph is being generated and the first point is red but when I hover it , it return to its default color.
$(function () {
$('#container').highcharts({
chart: {
type: 'spline',
margin: [70, 50, 60, 80],
events: {
click: function (e) {
// find the clicked values and the series
var x = e.xAxis[0].value,
y = e.yAxis[0].value,
series = this.series[0];
var chart = this;
this.addSeries({
data: [{ x:x, y:y, marker:{radius: 5 , fillColor: "red" }},{x:(x*2), y:(y*2)}]
})
}
}
},
title: {
text: 'User supplied data'
},
subtitle: {
text: 'Click the plot area to add a point. Click a point to remove it.'
},
xAxis: {
gridLineWidth: 1,
minPadding: 0.2,
maxPadding: 0.2,
maxZoom: 60
},
yAxis: {
title: {
text: 'Value'
},
minPadding: 0.2,
maxPadding: 0.2,
maxZoom: 60,
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
legend: {
enabled: false
},
exporting: {
enabled: false
},
plotOptions: {
series: {
lineWidth: 1,
point: {
events: {
'click': function () {
if (this.series.data.length > 1) {
this.remove();
}
}
}
}
}
},
series: [{
data: [[20, 20], [80, 80]]
}]
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="https://code.highcharts.com/modules/exporting.js"></script>
<div id="container" style="min-width: 310px; height: 400px; max-width: 700px; margin: 0 auto"></div>

Add in states option where you are setting the marker fillColor:
marker: {
radius: 5,
fillColor: 'red',
states: {
hover: {
fillColor: 'red',
}
}
}

Can I color points in highcharts time series?

Hey I have an example of Highchart timeseries.
In this example, I get all the points as array of small arrays(each array is a pair of x and y).
I would like to know if I could color specific point in current format using the fillColor attribute,if so how can I do it?
I want to highlight specific points in the time series graph, how can I do it?
$(function () {
$.getJSON('https://www.highcharts.com/samples/data/jsonp.php?filename=usdeur.json&callback=?', function (data) {
$('#container').highcharts({
chart: {
zoomType: 'x'
},
title: {
text: 'USD to EUR exchange rate over time'
},
subtitle: {
text: document.ontouchstart === undefined ?
'Click and drag in the plot area to zoom in' : 'Pinch the chart to zoom in'
},
xAxis: {
type: 'datetime'
},
yAxis: {
title: {
text: 'Exchange rate'
}
},
legend: {
enabled: false
},
plotOptions: {
area: {
fillColor: {
linearGradient: {
x1: 0,
y1: 0,
x2: 0,
y2: 1
},
stops: [
[0, Highcharts.getOptions().colors[0]],
[1, Highcharts.Color(Highcharts.getOptions().colors[0]).setOpacity(0).get('rgba')]
]
},
marker: {
radius: 2
},
lineWidth: 1,
states: {
hover: {
lineWidth: 1
}
},
threshold: null
}
},
series: [{
type: 'area',
name: 'USD to EUR',
data: data
}]
});
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="https://code.highcharts.com/modules/exporting.js"></script>
<div id="container" style="min-width: 310px; height: 400px; margin: 0 auto"></div>

You have two possibilites,
1) declare the color in the point object
{
x: 0,
y: 10,
color: 'red'
}
2) set a color by point.update()
chart.series[0].data[0].update({
color: 'red'
});
