high charts starting new line from each point

I am using high charts to show energy data but i think due to some negative value high caharts starting a new line from each new point and lines not have any connection between them.
here is the picture of my results.
problem Image
you can see in the image there should be only one line.
here's my data for this.
I have 4 series's to show in graph but here i am only providing one because each line have same issue
var data={'vt':[[1588273200000, 0],[1586372400000, 245],[1586286000000, 200],[1586199600000, 7],[1586113200000, 4],[1586026800000, 1],[1585940400000, 4],[1588186800000, 40],[1585854000000, 7],[1588100400000, 30],[1588014000000, 155],[1587927600000, 38],[1587841200000, 57],[1587754800000, 35],[1587668400000, 66],[1587582000000, 68],[1587495600000, 35],[1587409200000, 40],[1587322800000, 62],[1585767600000, 8],[1587236400000, 37],[1587150000000, 44],[1587063600000, 72],[1586977200000, 13],[1586890800000, 5],[1586804400000, 58],[1586718000000, 90],[1586631600000, 41],[1586545200000, 186],[1586458800000, -498]]};

You need to provide an external graph value for z-index which will identify its position
Please go through this fiddle link with ur dataset. I have improved ur code.
So you can review it.
https://jsfiddle.net/vishalanand77/f6dnua28/32

You have unsorted data - Highcharts error #15: https://www.highcharts.com/errors/15/
You can sort it in this way:
data.vt.sort(function(a, b) {
return a[0] - b[0];
});

HighCharts yAxis too much space around big numbers

My current chart
Just started using HighCharts. I'm charting a stock price that fluctautes around $1,598 and $1,601 that fluctuates over the course of a day. The changes are all obviously small - but the price is changing - it should not be a straight line. HighCharts seems to just zoom too far out. I've added the startOnTick: false etc. with no luck so far. Is there anything obvious I might be missing?
Options below:
const options = {
chart: {
height: '150px',
backgroundColor: theme.colors.white02
margin: 0,
spacing: [0, 0, 0, 0]
},
xAxis: {
title: {
text: null
},
labels: {
enabled: false
},
startOnTick: false,
endOnTick: false,
type: 'datetime',
gridLineWidth: 1,
},
yAxis: {
title: {
text: null
},
labels: {
enabled: false
},
startOnTick: false,
minPadding: 10,
maxPadding: 0
},
title: {
text: null
},
legend: {
enabled: false
},
series: [
{
type: 'areaspline',
data: data[0].data,
}
]
};

If you set the min option for the y-Axis to a number just below your minimum - in your case perhaps 1595, and have startOnTick to false as you've mentioned, that will essentially 'zoom in' on the graph right away for your desired range given the inputs are within that range.

Try to set min value of yAxis.
const options = {
chart: {
height: '150px',
backgroundColor: theme.colors.white02
margin: 0,
spacing: [0, 0, 0, 0]
},
xAxis: {
title: {
text: null
},
labels: {
enabled: false
},
startOnTick: false,
endOnTick: false,
type: 'datetime',
gridLineWidth: 1,
},
yAxis: {
title: {
text: null
},
labels: {
enabled: false
},
startOnTick: false,
minPadding: 10,
maxPadding: 0,
min: 1550
},
title: {
text: null
},
legend: {
enabled: false
},
series: [
{
type: 'areaspline',
data: data[0].data,
}
]
};
options.yAxis.min=1550;
or you can assign minimal value from response array.

How can I align the scale on my HighCharts graph with the axis rather than the margins?

By default, the scale for the x-axis and y-axis are on the bottom & left of the chart, respectively, as you can see here: http://jsfiddle.net/z7eyv/60/
I want them adjacent to the plot lines (the x- and y-axis). Here's an illustration of what I'm hoping to achieve: imgur.com/a/tf53t
I know that I can use offset: to move the scales to a specific pixel location, but they no longer align to the plot lines if I change the maximum/minimum values on either axis.
I labeled where I think offset should go in the code below, but I'm not sure what to type after it.
Here's the specific part of the code in question:
yAxis: {
min: -20,
max: 20,
tickInterval: 1,
endOnTick: false,
title: {
text: ''
},
plotLines: [{
value: 0.1,
width: 1,
color: 'black'}]
},
plotOptions: {
series: {
states: {
hover: {
enabled: false,
halo: {
size: 0
}
}
}
}
},
xAxis: {
min: -20,
max: 14,
tickInterval: 1,
gridLineWidth: 1,
endOnTick: false,
offset: //???????????????????????????????????????
title: {
text: '',
},
plotLines: [{
value: 0.1,
width: 1,
color: 'black'}]
},

As I have mentioned in my comments, you can use 'crossing-specific-values' plugin, available in Highcharts plugin repository:
https://www.highcharts.com/plugin-registry/single/6/Crossing-Specific-Values
You should be able to use labels.y option for moving your labels up/down
http://api.highcharts.com/highcharts/yAxis.labels.y
You should also be able to disable 0 values from your labels using labels.formatter:
http://api.highcharts.com/highcharts/yAxis.labels.formatter
yAxis: {
min: -20,
max: 20,
crossing: 0,
labels: {
formatter: function() {
return this.value ? this.value : ''
}
},
tickInterval: 1,
endOnTick: false,
title: {
text: ''
},
plotLines: [{
value: 0.1,
width: 1,
color: 'black'
}]
},
plotOptions: {
series: {
states: {
hover: {
enabled: false,
halo: {
size: 0
}
}
}
}
},
xAxis: {
min: -20,
max: 14,
crossing: 0,
opposite: true,
visible: true,
tickInterval: 1,
gridLineWidth: 1,
endOnTick: false,
labels: {
y: 13,
formatter: function() {
return this.value ? this.value : ''
}
},
title: {
text: '',
},
plotLines: [{
value: 0.1,
width: 1,
color: 'black'
}]
},

Why my label are not at the same height

My question is about a column chart i making..
I don't understand why my label are not set on the height..
I try many things but i really don't know..
Here you can find a example :jsfiddle project
$(function() {
var chart;
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'column',
height: 200
},
title: {
text: 'Monthly Average Rainfall'
},
xAxis: {
offset: 0,
labels: {
useHTML: true,
rotation: 0
},
tickmarkPlacement: 'on',
gridLineWidth: 0,
lineWidth: 0,
tickPosition: 'outside'
},
yAxis: {
gridLineWidth: 0,
plotLines: [{
color: '#DDDDDD',
width: 1,
value: 0
}],
max: 0.92,
labels: {
enabled: false
},
title: {
text: ''
}
},
credits: {
enabled: false
},
tooltip: {
enabled: false,
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0,
stacking: 'normal',
dataLabels: {
enabled: true,
color: 'black',
verticalAlign: 'top',
useHTML: true,
y: -20
}
},
},
series: [{
showInLegend: false,
negativeColor: '#F14646',
color: '#00B76C',
pointWidth: 40,
data: [0.01, 0.03, 0.03, 0.05, 0.03, 0.10, 0.11, 0.11, 0.15, 0.92]
}]
})
});
});
Thank you!!

It seems that plotOptions.column.stacking = 'normal' and plotOptions.column.y: -20 are causing most of the trouble. So, firstly you should set plotOptions.column.y: 0 (or remove it). Secondly, you could do one of the following
remove plotOptions.column.stacking entirely if you do not actually need it
some column labels may still be shown inside the bar instead of above, this is because there is not enough space above the column - one option is to set yAxis.max to a large enough value to guarantee space
if you do need stacking, use yAxis.stackLabels.enabled: true instead (and remove plotOptions.column.dataLabels if they interfere)
See the relevant Highcharts yAxis.stackLabels option documentation and their stacked column chart example.

line chart using secondary y-axis with negative percentage value

I have two y-axis.
using primary y-axis I have created column chart but when I am trying to create line chart using secondary y-axis with negative percentage data values my line chart is going down from x-axis I don't want that so do anyone know about this please help me as soon as possible ?
$(function () {
$('#container').highcharts({
colors: [ '#24CBE5','#FF9655'],
chart: {
type: 'column'
},
title: {
text: 'combine chart'
},
plotOptions: {
series: {
pointPadding:0,
groupPadding:0.3,
borderWidth: 1,
//shadow: false
}
},
xAxis: {
gridLineWidth: 0,
minorGridLineWidth: 0,
categories: ['Oct 15', 'Nov 15', 'Dec 15', 'Jan 15', 'Feb 15','March 15'],
},
yAxis: [{ // Primary yAxis
min: 0,
max: 4,
gridLineWidth: 0,
minorGridLineWidth: 0,
labels: {
formatter: function () {
return this.value + '$';
}
},
title: {
text: 'Million',
}
}, { // Secondary yAxis
tickInterval:5, //set ticks to 20
min: -30,
max: 10,
column :{
stacking:'percent'
},
title: {
text: '% Percantage',
},
labels: {
formatter: function () {
return this.value + '%';
}
},
opposite: true
}],
series: [
{
type: 'column',
name: 'AB',
data: [3, 3.5, 3.3, 3.6, 2.5,2]
}, {
type: 'column',
name: 'BC',
data: [3.3, 2, 3.3, 3.4, 2.9,3]
}, {
// USE THIS CODE TO GENERATE LINE CHART (I HAVE USED ONLY MILION AND CREATED LINE CHART BUT INSTEAD I WANT TO USE percentage )
type: 'line',
name: '% Percantage',
data: [0.5, 2, 0, 4, 3.7,2.6],
color: '#000000',
//border: 1,
marker: {
fillColor: '#FFFFFF',
lineWidth: 2,
lineColor: null // inherit from series
}
}]
});
});

You need to set alignTicks as false.
chart:{
alignTicks: false
}
