Add vertical(projection) line from point to categories, highcharts - javascript

I have a areaspline plot(stacked), and what I need now is add a projection line from the toppest point(not chart) to the corresponding category. like:
I lookup on the api reference about xAxis but did not find what I want.

You can use plotLines
xAxis:{
plotLines: [{
color: '#ffffff',
width: 2,
value: 5.5
}]
}
or gridLines
xAxis: {
gridLineColor: '#fff'
},

Hight Chart Polar Scatter Plot values on chart and x-axis

I want to create chart as per below image. I have also created jsfiddle using highchart in the fiddle.

appreciated.

jsfiddle - Highcharts Example
You can use basic yAxis to show ticks with labels, but you will need the right properties and wrap on getMarkPath method:
yAxis: {
lineWidth: 1,
tickPosition: 'inside',
showLastLabel: true,
tickWidth: 1,
tickColor: '#000000',
angle: 90,
tickInterval: 1,
labels: {
y: -10
},
lineColor: '#000000'
}

What should I do to make the x-axis of a graph bold with Highchart?

Note that the x-axis here means the horizontal line which corresponds the 0 value, i.e. the desired result is:
However, I can only achieve this.
This is the relevant piece of code:
xAxis: {
lineColor: 'black',
lineWidth: 2
},
How to decide which horizontal line to be bolded?
You can draw a line on the Y-axis at position 0. This causes for a horizontal line to be drawn at value '0'. This is done by the highcharts option plotLines
Highcharts.chart('container', {
yAxis: {
min: -1,
max: 4,
plotLines: [{
value: 0,
color: 'black',
width: 2,
zIndex: 3
}],
},
series: [{
data: [1, 2, 3]
}]
});

Highchart / Highstock how to set color of individual ohlc or candle?

I have set up a highstock ohlc with angular 2. But can not set the up and down color for OHLC chart type, for example, green when hclose is increasing and red when it is decreasing. is there any API reference for that or any way to implement? like this below image I want my chart to look like..
I found a way like this and its working :-)
plotOptions: {
ohlc: {
color: 'red',
upColor: 'green'
}
},
series : [{
type: 'ohlc',
name : 'Stock Price',
data : [],
yAxis : 0,
}, {
type: 'column',
name : 'volume',
data : [],
yAxis : 1,
}]
You can use these to change the colors for down line and up line colors as well.
plotOptions: {
candlestick: {
color: 'red',
upColor: 'green'
lineColor: 'red',
upLineColor: 'green'
}
}

Highcharts plotLines with multiple xAxis and yAxis

I have a chart with multiple xAxis and yAxis. I want to have multiple plotLines on the xAxis, but each plotLine doesn't stay on it's course. Here's the fiddle. Click on All to see what I mean.
The plotLine on the first axis goes to the second axis as well. How could I stop it?
There is a solution suggested in the HighCharts issue tracker which involves defining the related xAxis on each yAxis. So a plotline defined on a particular xAxis will use the top and height of the related yAxis to draw the plotline only in the correct area.
yAxis: [{
title: {
text: 'OHLC'
},
height: 200,
lineWidth: 2,
xAxis: 0,
}, {
title: {
text: 'Volume'
},
top: 300,
height: 100,
offset: 0,
lineWidth: 2,
xAxis: 1,
}, {
title: {
text: 'Other data panel'
},
top: 300,
height: 100,
offset: 0,
lineWidth: 2,
opposite: true,
xAxis: 1,
}]
Updated Fiddle with each plotline only on its corresponding pane.
Note that the ability to define related axes appears to be undocumented in the API.

Is it possible to have two Y Axis in a highstock chart from highcharts one on the left and another on the right?

Is it possible to have 2 yAxis in a highstock chart from highcharts one on the left and another on the right ?
Thanks
A very simple example:
First you have to create your new yAxis and set it's position.
{
title: {
text: 'Other data panel'
},
top: 300,
height: 100,
offset: 0,
lineWidth: 2,
opposite: true
}
Then, when you create your serie you in what yAxis it will be placed.
{
type: 'column',
name: 'Other',
data: otherData,
yAxis: 2,
dataGrouping: {
units: groupingUnits
}
}
You can see it working here.
