highcharts: epoch time not properly connected to Xaxis - javascript

When i have inconsistent data coming in (when for example the server that gathers the data is down) highcharts does not plot the X correctly.
It still plots like there is data on the X while there is not.
It should afcouse plot the correct hour when there actually is data.
Here is the fiddle: http://jsfiddle.net/ZVwFK/
Data variable is inconsistant!
Can someone show me how i can correct this error?

There are two ways of specifying time data for Highcharts and I think you are using the wrong way for the problem. It's the second style you should use when having gaps in the data.
A compact array without gaps only containing the values for each time-point
data: [2, 5, 3, 6, 1]
Then you specify the time-point for the first measure together with the interval. eg:
pointStart: Date.UTC(2013,1,12), // start point in milliseconds
pointInterval: 3600 // interval in milliseconds
You cannot have different length between the time-points this way.
A two dimensional array with both time-points and measure
data: [[Date.UTC(2013,1,12), 2],
[Date.UTC(2013,1,12), 5],
[Date.UTC(2013,1,12), 3],
...]
This way of specifying the array can have gaps where there's no data.
See the reference here
and example here.

How to render x-axis labels in Highcharts without the decimal points?

I need to display my x-axis label as a whole number with percentage without the decimal and a zero before it. I am already using allowDecimals: false but that's not helping it looks like. How can I fix this?
0.10% should render as 10% and etc.

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];
});

Zoom option in Highchart not working for large amount of data

I need to create a highchart with jquery. I have given the Zoom type as x. The Zoom option in chart is not working when there are large amount of data.
In my X-Axis I will be having date value :
Below is my chart implementation:
// Global chart options
Highcharts.setOptions({
chart: {
borderRadius: 0,
borderWidth: 1,
borderColor: '#DADCE0',
marginRight: 45,

rotation: 45
}
},
plotOptions: {

fillOpacity:0.1
},

marker: {

},

states: {
hover: {
enabled: true
}
}
},
lineWidth: 1,
threshold: null
}
},
global: {
useUTC: false
}
});
var chartJobCount = new Highcharts.Chart({
chart: {
renderTo: 'container-segementReport',
type: 'areaspline'
},
colors: ['#0D4F8B','#00CCFF', '#ff0000', '#ff69b4','#663399','#ffa500','#006400','#654321'],
title: {
text: 'Segments (Classic)'
},
yAxis: {
title: {
text: 'Production Ratio'
},
labels: {
formatter: function () {
return Highcharts.numberFormat(this.value, 0, '', ',');
}
}
},
tooltip: {
formatter: function () {
return '<b>' + this.series.name + ' </b> <br/> Date : <b>' + Highcharts.dateFormat('%m-%d-%Y', this.x) + ' </b> <br/> Production Ratio: <b>' + this.y + '</b>';
}
},
series: getProductionRatio() --// This function will get the data for series
});
When I try to zoom the chart, the contents present in the chart gets hided.
Is there anything that needs to taken care in the point interval for X-Axis ?
Thanks in Advance !

highcharts: 3rd Y axis on wrong side

I am trying to plot 3 Y axis with a seperate scale.
The problem is that the Air pressure 'text' of the scale in on the 'opposite' side of the plot (where it should be), but not the 'number' scale.

yAxis: 4 on the Air pressure series fixed it.
Also added linkedTo: 0, to other series connected to temperature.

Highchart crashing with multiple Y axis

});
You only have one yAxis, so it breaks because you set the second serie to display into the second one( yes, that's what yAxis: 1 means ).
Remove it or create the second yAxis.
Update:
Use yAxis: 0 the reffer the first and 1 to the second.
Missing , after } on line 36 of jsfiddle.
Store data before.
