Why would the label of the vertical axis only show after the button is clicked?

I am working on a website which needs to show something on the chart (highchart) upon clicking of a button.
The issue is: when the page is first loaded, the label on the vertical axis can not be seen, no matter how big I set the margin for the chart. However, after the button is clicked for the first time, the labels can be seen and remains so.
There was no such problem before I set "reversed", "opposite" for xAxis and "reversed" for yAxis as true.
What causes this phenomenon and how can I solve this?
See the JSFiddle for detail. (There are some logic mistakes in the code which is irrelevant for my question.)
I just discovered that when I first load the JSFiddle, the vertical axis of the graph shows up with label; but when I click on "Run" additionally, the graph is refreshed with a vertical axis without label. Maybe I can simulate certain process which takes place when a JSFiddle is loaded to make sure that the vertical axis of the graph shows up with labels. But I am not sure how to do that.

Code for the generation of the chart:

var chart = new Highcharts.Chart({
chart: { //not to be changed lightly

fontWeight: "unbold"
},
formatter: function() {
return Math.round(chartData[index - 2] * 100) / 100;
}
},
plotOptions: {
bar: {
dataLabels: {
enabled: false
}
},
series: {
borderColor: '#FFFFFF',
animation: false, //disable all the animations,
pointPadding: 0,
groupPadding: 0,
borderWidth: 1,
shadow: false
}
},
series: [{
enableMouseTracking: false,
data: Array(7).fill(0)
}]
});
return chart;
}

So, it's only possible to reproduce on Windows platform. Could you provide us also with minified demo where the problem occurs? I'm asking because in current demo there are a lot of lines which are unnecessary.
Additionally, until we find the source of the problem, you can workaround it by calling this.reflow() in chart.events.load event handler.
chart: {
events: {
load: function() {
this.reflow()
}
}
}
API Reference: https://api.highcharts.com/class-reference/Highcharts.Chart#reflow

I'm not sure why but it works fine when you remove the marginLeft property or set it to 0.

Highcharts - Solid Gauge - Inconsistent Styling and Improper Values

I have a website which makes use of HighCharts Solid Gauge .
There are two rows of gauges.
The first row of gauges is built as follows.
var workgroups =['WG01','WG02','WG04',
'WG05','WG06','All'];
$(function ()
{
var gaugeOptions = {
chart: {
type: 'solidgauge'
},
title: 'Gauge',
pane: {
// Positioning
center: ['50%', '60%'],
// img size
size: '100%',
// full circle/half circle
startAngle: -90,
endAngle: 90,
// gauge coloring
background: {
backgroundColor: (Highcharts.theme && Highcharts.theme.background2) || '#000',
// Inner semi circle sizing
innerRadius: '60%',
outerRadius: '100%',
shape: 'arc'
}
},
tooltip: {
enabled: false
},
// the value axis
yAxis: {
stops: [
// Set the limits for coloring
[0.1, '#55BF3B'], // green
[0.4, '#DDDF0D'], // yellow
[0.9, '#DF5353'] // red
],
// Outside Line buffer
lineWidth: 0,
minorTickInterval: null,
tickPixelInterval: 400,
tickWidth: 0,
title: {
// Title Location
y: -30
},
labels: {
style:{
color: "#000000",
fontSize: "13px"
},
// Bottom Label Offset
y: 15,
distance: -10,
}
},
plotOptions: {
solidgauge: {
dataLabels: {
style:{
color: "000000",
fontSize: "15px"
},
borderWidth: 0,
useHTML: true
}
}
}
};
// The gauges
for( i in workgroups){
if(workgroups[i] == 'All'){
header = "All";
gaugeOptions.yAxis['stops'] = [[.5, '#000000']]
}else{
header = "WG" + workgroups[i].slice(-2);
}
$('#'+workgroups[i]).highcharts(Highcharts.merge(gaugeOptions, {
yAxis: {
min: 0,
max: 100,
title: {
style:{
color: "#000000",
fontWeight: 'bold',
fontSize: '22px'
},
text: header
}
},
credits: {
enabled: false
},
series: [{
name: workgroups[i],
data: [0],
dataLabels: {
y: 40,
format: '<div style="text-align:center"><span style="font-size:25px;color:' +
((Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black') + '">{y}</span><br/>' +
'<span style="font-size:12px;color:silver">clients</span></div>'
},
}]
}));
}
}
);
and results in the following image.
This is fine, proper values, all styles fit where they are supposed to.
After doing these gauges, we then do a second row of gauges.
The (Current) Configuration for these gauges are:
var application_array = new Array(3);
application_array['Sapphire'] = 50;
application_array['Magic Bullet'] = 35;
application_array['Boris'] = 30;
$(function ()
{
var gaugeOptions = {
chart: {
type: 'solidgauge'
},
title: 'Gauge',
pane: {
// Positioning
center: ['50%', '85%'],
// img size
size: '150%',
// full circle/half circle
startAngle: -90,
endAngle: 90,
// gauge coloring
background: {
backgroundColor: (Highcharts.theme && Highcharts.theme.background2) || '#000',
// Inner semi circle sizing
innerRadius: '60%',
outerRadius: '100%',
shape: 'arc'
}
},
tooltip: {
enabled: false
},
// the value axis
yAxis: {
stops: [
// Set the limits for coloring
[0.1, '#55BF3B'], // green
[0.4, '#DDDF0D'], // yellow
[0.9, '#DF5353'] // red
],
// Outside Line buffer
lineWidth: 0,
minorTickInterval: null,
tickPixelInterval: 400,
tickWidth: 0,
title: {
// Title Location
y: -30
},
labels:{
y:13
}
},
};
// Build the gauges here
var license_gauges = document.getElementsByClassName('gaugeCell2');
var myLength = license_gauges.length;
for (i=0; i <myLength; i++){
var header = license_gauges[i].id;
var selector = "[id='"+header+"']";
if (header == 'Boris'){
var max_value = 30;
}else if (header == 'Magic Bullet'){
var max_value = 35;
}else if (header == 'Sapphire'){
var max_value = 50;
}
console.log(header)
$(selector).highcharts(Highcharts.merge(gaugeOptions, {
yAxis: {
min: 0,
max: max_value,
title: {
style:{
color: "#000000",
fontWeight: 'bold',
fontSize: '22px'
},
text: header
}
},
credits: {
enabled: false
},
series: [{
name: header,
data: [0],
}]
}));
}
});
Which Produces the following BAD Gauges
My Question
1) In the second row of gauges, Why is it printing 25 as max for the 2nd and 3rd gauge?
- I have tried an associate array to hold the proper value, same issue occurs
I have tried a function which returns a static value, same issue occurs
I have tried logic in the gauge creation itself, same issue occurs
I have tried writing a static value as max, and all gauges get the proper value
2) In the second row of gauges, why is it that the max Value, for the second and third gauges is inconsistently formatted with the first gauge?
I have tried virtually every layout configuration I can think of, but yet it stays the same issue.
When Using a static max value, this issue does not occur.
Do I need to make an individual gaugeoption for each gauge since they have different max values? I would like to use 1 gauge style for the top row and 1 gauge style for the bottom row (fatter).
A JSFiddle has been created here. There is most likely extraneous code (especially css), as I wanted to get it up and running quickly.

Thanks for reading

Why is it printing 25 as max for the 2nd and 3rd gauge?
It isn't. That is, the max isn't 25, but the drawn axis label shows the value 25, as there is an axis tick at this value. The max value is not showing with a label.
why is it that the max Value, for the second and third gauges is inconsistently formatted with the first gauge?
The position is inconsistent because the 25 label is in varying positions depending on what the max value is. In your case it is 35 and 30 for the last two gauges.
Do I need to make an individual gaugeoption for each gauge since they have different max values?
No. From my understanding you want a label at the start (0) and end (max_value). To get this you need to ensure that the axis ticks (which have associated labels) are at these positions, and only these.
A simple way is this (JSFiddle):
yAxis: {
min: 0,
max: max_value,
tickPositions: [0, max_value], // Ensure position of ticks, which have labels
// ...
}

I was having the same issue, but following what Halvor Strang said solved my problem like so
displayOptions.yAxis.min = widget.display.minimum;
displayOptions.yAxis.max = widget.display.maximum;
displayOptions.yAxis.tickPositions = [widget.display.minimum, widget.display.maximum];
distorted labels
- Minimum and maximum out of place

Highchart scrollbar and two x axis

I have a little problem with my meteogram which I created in highchart. I have two x axises (on the top and on the bottom of my chart). I enabled scrollbar (I'm using highstock) and this scrollbar affected only on my bottom axis. When I move my scroll only bottom axis scrolls. I also want to move my top axis. How to do that? There is no 'scroll' option in reference to axis, only global:
scrollbar: {
enabled: true
}
Here you can see how it looks like:
Top categories doesn't change when we move scroll. Only bottom are changing.
Here is code resposible for x axises creation:
xAxis: [ {
categories: prepareCategories(jsonData),
min: 0,
max: 25,
tickInterval: 8,
tickWidth: 2,
plotLines: preparePlotLines(jsonData)
}, {
categories: prepareWindCategories(jsonData),
min: 0,
max: 25,
tickInterval: 2,
tickWidth: 2,
opposite: true,
labels: {
useHTML: true,
formatter: function() {
return prepareWindLabel(this.value.wind, this.value.windDirection);
}
}
} ],

Highcharts : Display the labels (min, max, median etc.) in boxplot

I have created a basic boxplot using highcharts and it shows me the values for maximum, max quartile, median, min quartile and minimum when I hover the mouse over the box plot. I want to somehow display these values in the plot itself beside each of the lines.
I checked out the api and found that "dataLabel" would help but this is not supported for the boxplot. Could someone enlighten me on how to achieve this?
Thanks.

Not possible out of the box, but as mentioned by Steve Gu achievable by scatter. You can even ignore the formatter and disable the marker alltogether:
{
series: [
{
type: 'scatter',
tooltip: {
enabled: false
},
dataLabels: {
format: '{key}',
enabled: true,
y: 0,
},
data: [{ x: 0, y: 975, name: '975'}],
marker: {
enabled: false,
}
}
]
}
just disable marker and set format to key.

Add another data series, which is a type of "Scatter" and apply the data labels to this series using Marker. The trick is to use the same fill color as your background color and 0 line width so the marker will not be visible and only the label will be shown.
{
name: 'Outlier',
color: 'white',
type: 'scatter',
data: [ // x, y positions where 0 is the first category
{
name: 'This is my label for the box',
x:0, //box index. first one is 0.
y:975 //it will be bigger than the maximum value of of the box
}
],
dataLabels : {
align: 'left',
enabled : true,
formatter : function() {
return this.point.name;
},
y: 10,
},
marker: {
fillColor: 'white',
lineWidth: 0,
lineColor: 'white'
}
}

Unfortunately this option is not supported, only what you can do is use renderer to add custom text inside chart, but I'm aware that it can be not comfortable solution. http://api.highcharts.com/highcharts#Renderer.text()
Obviosuly you can reqest your suggestion in our user voice system http://highcharts.uservoice.com/

How to stop zooming out in Flot bar chart?

I am using Flot to draw some bar charts. How do I configure the zoom so that when a user zooms out, the chart will look like the one at the top and not like the one at the bottom? In other words, I don't want the user to continue zooming out when all of the data for the chart is shown. I also want to restrict the chart from displaying anything below 0 on the X axis. See my code and pictures of the charts below:
<#macro barChart2 var formatFunction ticks="" optionLegend="{ show: false }">
var options = {
yaxis: {
tickFormatter: ${formatFunction}
},
series: {
stack: 0,
bars: {
show: true,
barWidth: 0.9,
align: "center"
}
},
grid : {
hoverable: true
},
xaxis: {
<#if "${ticks}" != "">
ticks: ${ticks}
</#if>
mode: "time",
timeformat: "%b %d, %H:%M %P"
},
pan : {
interactive: true
},
legend: ${optionLegend}
};
var plot${var} = $.plot($("#chart${var}"), data, options);
$("#zoomIn${var}").click(function(e) {
e.preventDefault();
plot${var}.zoom();
});
$("#zoomOut${var}").click(function(e) {
e.preventDefault();
plot${var}.zoomOut();
});
</#macro>

I suggest you take a look at the zoomRange and panRange parameters that you can set with the navigation plugin. You specify those for the axes like:
xaxis: { zoomRange: [0.1, 10], panRange: [-10, 10] },
yaxis: { zoomRange: [0.1, 10], panRange: [-10, 10] }
where zoomRange sets the limit for zooming. In this case, the difference between the min and max will never go below 0.1, and it will never exceed 10. panRange tells the content to stay in a certain range, so in this case, neither axis will pan below -10 or above 10.
I'm not sure how you do this with time series data, but try with javascript timestamps to begin with.
