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];
});

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.

Hi I try to create spider chart using high chart but it taking first 4 values(parm1,parm2,parm3,parm4) properly but not the other 4 values (data1,data2,data3,data4)
i am using this code to call these values finalResults.innerHTML += spiderChart (PM,AF,AT,AD,dataPM,dataAF,dataAT,dataAD) + "<br>" values of PM,AF,AT and AD are showing properly in spider chat but for data dataPM,dataAF,dataAT,dataAD it is showing nothing ... i check the function by replacing variable with acctual value and it was working properly... please let me know what is wrong here ?

Above is the code for an Area range chart. Couple of questions.
I just want to show some random text on top of each area. I tried with dataLabels but I doesn't seem to work. Isn't it possible to do so?
Yaxis seems to be shown in AreaRange chart when mouse is hovered over the chart. Can it be set to be displayed by default?
Any help would be much appreciated. Thanks in advance.
I tried to reproduce your code and here is an output: https://jsfiddle.net/BlackLabel/uqmyjsr9/
The dataLabels config needs to be nested in the series object.
plotOptions: {
series: {
//stacking: 'normal',
borderColor: '#303030',
color: '#cac9c9',
lineWidth: 1,
marker: {
lineWidth: 1,
lineColor: '#303030'
},
dataLabels: {
useHTML: true,
enabled: true,
inside: true,
align: 'left',
allowDecimals: true,
formatter: function() {
return "SOME_TEXT_INSIDE_HTML_TAG";
}
},
},
},
I am not sure here - the yAxis is displayed all the time, not only after hovering over the chart.
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.

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.
