I'm playing with the apexchart.js library and getting this mismatched graph. I want to display an area graph, where the X line is a collection of date-times and the Y line has some values (floating type).
On the picture, you can see the library set the bad zero point for some series.
Here are my settings for the graph.
let options = {
chart: {
height: 390,
type: 'area',
stacked: false
},
dataLabels: {
enabled: false
},
series: [{
name: "Power – Total",
data: powerTotal,
type: 'area'
},
{
name: "Power – Solar A",
data: powerSolarA,
type: 'area'
},
{
name: "Power – Solar B",
data: powerSolarB,
type: 'area'
},
{
name: "Consumption",
data: consumption,
type: 'area'
},
{
name: "Battery",
data: batteryPower,
type: 'area'
},
{
name: "Grid",
data: gridPower,
type: 'area'
},
],
xaxis: {
type: 'datetime',
categories: datetimes,
labels: {
datetimeUTC: false
}
},
yaxis: [
{
seriesName: 'Power – Total',
title: {
text: "kW"
},
decimalsInFloat: 2,
showAlways: true,
floating: false,
},
{
seriesName: 'Power – Solar A',
show: false,
floating: false,
},
{
seriesName: 'Power – Solar B',
show: false,
floating: false,
},
{
seriesName: 'Consumption',
show: false,
floating: false,
},
{
seriesName: 'Battery',
show: false,
floating: false,
},
{
seriesName: 'Grid',
show: false,
floating: false,
},
],
markers: {
size: 0,
hover: {
size: undefined,
sizeOffset: 3
}
},
colors: lineColors,
tooltip: {
x: {
format: "dd:MM:yyy HH:mm"
}
},
fill: {
opacity: .6,
type: 'solid'
},
stroke: {
show: true,
curve: 'straight',
width: [2, 2, 2, 2, 2, 2, 4]
},
grid: {
show: true
},
legend: {
itemMargin: {
vertical: 24
}
}
};
Does anybody know what it can be?
Thanks

I am trying to get both lines on my chart to scale correctly, I have read through the documentation but can't seem to find how to do this.

The above image shows what happens to the orange line when a secondary axis is added. It's like they are using the same scale rather than their own.
I currently have the below code:
$(function(e) {
/*-----echart1-----*/
var options = {
chart: {

type: "line",
stacked: false,

opacity: 0.1,
},
},

dataLabels: {
enabled: false
},
stroke: {
curve: "straight",
width: [3, 3, 0],
dashArray: [0, 4],
lineCap: "round"
},
grid: {
padding: {
left: 0,
right: 0
},
strokeDashArray: 3
},
markers: {

}
},

I have code from this post. I want to populate the chart on click of a button instead of initializing it and provide only 3 values e.g.22286,12286,9286 ( these values would be dynamic) and plot the chart with the same appearance (i.e. 3 colors chart) as of the snippet
Highcharts.chart('container', {

series.forEach(function(s) {
tickPositions.push(s.processedYData[s.processedYData.length - 1]);
});
tickPositions.sort(function(a, b) {
return a - b;

return tickPositions;

All you need to do is to create series with empty data array and use chart.update method to add data. Example:
var chart = Highcharts.chart('container', {
...,
series: [{
data: []
}, {
data: []
}, {
data: []
}]
});
document.getElementById('chartInit').addEventListener('click', function(){
chart.update({
series: [{
data: [4457, 13371, 22286]
}, {
data: [2457, 9371, 12286]
}, {
data: [1457, 5371, 9286]
}]
});
});

I have one Highchart which is showing a Standard Deviation curve (Bell curve). I would like to plot a x axis vertical line when x=0.(see my current graph).
When I include the code to include the line the chart disappear, so I believe something I need to change, obviously :-).
Just as information the chart works perfectly without the "plotLines:" inside xAxis.
Could you help me with this?
See my Script
<script>
var data = <?php echo json_encode($data, JSON_NUMERIC_CHECK); ?>;
var pointsInInterval = 5;
Highcharts.chart('container', {
chart: {
margin: [50, 0, 50, 50],
events: {
load: function () {
Highcharts.each(this.series[0].data, function (point, i) {
var labels = ['4σ', '3σ', '2σ', 'σ', 'μ', 'σ', '2σ', '3σ', '4σ'];
if (i % pointsInInterval === 0) {
point.update({
color: 'red',
dataLabels: {
enabled: true,
format: labels[Math.floor(i / pointsInInterval)],
overflow: 'none',
crop: false,
y: -2,
style: {
fontSize: '13px'
}
}
});
}
});
}
}
},
title: {
text: null
},
legend: {
enabled: false
},
xAxis: [{
title: {
text: 'Data'
},
visible: false
}, {
title: {
text: 'Bell curve'
},
opposite: false,
visible: true
},
plotLines: [{
color: '#FF0000',
width: 2,
value: 0
}]
],
yAxis: [{
title: {
text: 'Data'
},
visible: false
}, {
title: {
text: 'Bell curve'
},
opposite: false,
visible: true
}],
series: [{
name: 'Bell curve asd',
type: 'bellcurve',
xAxis: 1,
yAxis: 1,
pointsInInterval: pointsInInterval,
intervals: 4,
baseSeries: 1,
zIndex: -1,
marker: {
enabled: true
}
}, {
name: 'Data',
type: 'scatter',
data: data,
visible: false,
marker: {
radius: 1.5
}
}],
exporting: {
allowHTML: true,
sourceWidth: 800,
sourceHeight: 600
}
});
</script>
Plot lines should be added as a property of an axis object:
xAxis: [{
title: {
text: 'Data'
},
visible: false
}, {
title: {
text: 'Bell curve'
},
opposite: false,
visible: true,
plotLines: [{
color: '#FF0000',
width: 2,
value: 0
}]
}
]

I have trouble with performance of my highstock. All works, but time of plotting of my data is too slow, about 30 seconds. JSON is about 30000 points. Maybe problem in how I draw this data ? I already turn off animation, shadow, marks etc.
And here is my JS code:
$(function() {
Highcharts.setOptions({
global: {
useUTC: false,
timezoneOffset: - 3 * 60
}
});
function requestData() {
$.ajax({
url: 'values.php',
success: function(series) {
chart.addSeries({name: 'Temp1', data: series[0], yAxis:0}, false);
chart.addSeries({name: 'Temp2', data: series[1], yAxis:0}, false);
chart.redraw();
},
cache: false
});
}
chart = new Highcharts.StockChart({
chart: {
animation: false,
zoomType: 'xy',
renderTo: 'container',
events: {
load: requestData
}
},
title: {

}],

// tickInterval: 100*3600,

return Highcharts.dateFormat('%H:%M:%S',this.value);
}
}
},
yAxis: {

style: {
color: Highcharts.getOptions().colors[0]
}
},
title: {

},

Is it possible to move the y-position of the x-axis in highcharts? So far, I have only been able to move it to the top or bottom of my chart using
opposite: true/false
but now I need it to be in the middle of my graph, at a fixed y-value. My current code is
$(function () {
var chart;
$(document).ready(function () {
chart = new Highcharts.Chart({
chart: {
type: 'spline',
renderTo: 'container'
},
title: {
text: 'Title'
},
xAxis: {
opposite: true,
min: 0,
max: 4,
reversed: true,
startOnTick: true,
endOnTick: true,
lineWidth: 1
},
yAxis: {
labels: {
enabled: true
},
title: null,
gridLineWidth: 0,
min: 1,
max: 3.1
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
}
}
},
credits: {
enabled: false
},
series: [{
marker: {
enabled: false
},
name: 'Year 1800',
data: [
[1, 1],
[2.5, 1]
],
showInLegend: false
}, {
marker: {
enabled: false
},
name: 'Year 1900',
data: [
[1.5, 2],
[3, 2]
],
showInLegend: false
}, {
name: 'name1',
data: [
[2, 3]
],
type: 'scatter',
zindex: 10
}, {
name: 'name2',
data: [
[3, 3]
],
type: 'scatter'
}, {
name: 'name3',
data: [
[1.5, 3]
],
type: 'scatter'
}]
});
});
});

I want the x axis (along with the ticks and labels) to run through y=2.5, between the two different data sets. Does HighCharts support this?
You can use offset property to move xAxis. In your case you have to use negative offset to move xAxis down:
xAxis: {
opposite: true,
min: 0,
max: 4,
reversed: true,
startOnTick: true,
endOnTick: true,
lineWidth: 1,
offset: -130
},
$(function () {
Highcharts.setOptions({
global: {
useUTC: false
}
});
$('#container').highcharts({
chart: {
type: 'bar'
},
title: {
text : <%=jtitle%>
},
xAxis : {
min:Date.UTC(2016, 0, 0),
max:Date.UTC(2016, 11, 1),
//allowDecimals: false,
type : 'datetime',
tickInterval : 24 * 3600 * 1000*30, //one day
labels : {
rotation : 0
},
},
yAxis: {
dateTimeLabelFormats: {
day: '%Y' },
labels :{
formatter:function() {return Highcharts.dateFormat('%Y',this.value);}
},
title: {
text: 'Date'
},
plotLines: [{
value: 0,
width: 5,
color: '#808080'
}]
},
series : [
{
name : 'MB Data',
data : <%=datasp%>,
tooltip: {
valueDecimals: 2,
dateTimeLabelFormats: {
hour: '%H:%M'
}
}
},
{
name : 'Date & Time',
data : <%=datetime%>
},
]
});
});
