Hightchart issue, when more then one plot is used on page

I am working on page, where i need to have multiple plots, one being a solid gauge and the other being a line graph.
I am using the Ionic Framework 5 with angular and High Charts.
I am finding that when one plot is displayed, it works fine, but with more then one I am getting some type of conflict where the line chart does not get updated and the gauge gets data which is meant for the line graph.
This my code. Do i need to do anything in perticular?

How to make mPDF wait for my JS to finish

I am working with mPDF and Highchart. Both are working, but sometimes the PDF is created before the chart has finished loading (the chart tooks about 2 secods to load). I was wondering if it is possible to delay the mPDF execution, so it waits for the chart.
var chart = new Highcharts.Chart({
chart: {
renderTo: 'RDBMS',
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
type: 'pie'
},
colors: ['#6495ED', '#FFA07A','#9ACD32','#9370DB','#87CEFA'],
title: {
text: 'Servidores por RDBMS'
},
tooltip: {
pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: true,
format: '{point.y} <br> {point.percentage:.1f} %',
style: {
color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black'
}
},
showInLegend: true
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: [{
name: 'RDBMS',
colorByPoint: true,
data: [{
name: 'Mysql',
y: 40, //Dado dinamico
sliced: true,
selected: true
}, {
name: 'Oracle',
y: 6, //Dado dinamico
sliced: true
}, {
name: 'SQL Server',
y: 22, //Dado dinamico
sliced: true
}, {
name: 'DB2',
y: 9, //Dado dinamico
sliced: true
}, {
name: 'PostgreSQL',
y: 1, //Dado dinamico
sliced: true
}]
}]
});
var opts = chart.options;
opts = $.extend(true, {}, opts);
delete opts.chart.renderTo;
var strOpts = JSON.stringify(opts);
$.post(
'http://export.highcharts.com/',
{
content: 'options',
options: strOpts ,
type: 'image/jpg',
width: '100px',
scale: '1',
constr: 'Chart',
async: true
},
function(data){
var imgUrl = 'http://export.highcharts.com/' + data;
$('#charts').append("<img src='" + data + "' >");
}
);
This is my code that creates my chart. I call this function at the end of my page, after a table.
And this is what my page looks like printscreen

You need to disable animation
plotOptions: {
series: {
animation: false
}
}
Link to API doc

Execute mPDF after series initial animation is finished. You can do that using afterAnimate event.

how to add hover effect in hightcharts?

can we add hover effect in hightcharts (donut chart) ..Can we add hover effect in donut chart shown in given url
http://c3js.org/samples/chart_donut.html
please check above link and hover any slice .it dark the selected slice and grey out the other as same effect in legend
can we do in highcharts
here is the code
http://jsfiddle.net/sk0603wj/
$(function () {
Highcharts.chart('container', {
chart: {
plotBackgroundColor: null,
plotBorderWidth: 0,
plotShadow: false
},
title: {
text: 'Browser<br>shares<br>2015',
align: 'center',
verticalAlign: 'middle',
y: 40
},
tooltip: {
pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
},
plotOptions: {
pie: {
dataLabels: {
enabled: true,
distance: -50,
style: {
fontWeight: 'bold',
color: 'white'
}
},
startAngle: -90,
endAngle: 90,
center: ['50%', '75%']
}
},
series: [{
type: 'pie',
name: 'Browser share',
innerSize: '50%',
data: [
['Firefox', 10.38],
['IE', 56.33],
['Chrome', 24.03],
['Safari', 4.77],
['Opera', 0.91],
{
name: 'Proprietary or Undetectable',
y: 0.2,
dataLabels: {
enabled: false
}
}
]
}]
});
});

It can be done, but it is not very straight forward. Here you can see the building blocks of this:
http://jsfiddle.net/3ehrgge7/2/
1) you need to to remember the reference to the chart
var hc = Highcharts.chart(...
2) Then you can use mouseOver and mouseOut events on the elements to modify the points of the series. Here is an example of mouse over event, that for all but hovered item updates the color to something.
plotOptions: {
pie: {
point:{
events:{
mouseOver:function(ev){
hc.series[0].points.forEach(
function(i){
if(ev.target !== i ){
i.update({color:'rgba(150,100,50,0.1)'});
}
}
)
}
}
},
states: {
hover: {
halo: {
size: 9,
opacity: 0.75
}
}
}
}
}
3) To make the desired effect, you have to have a table of colors that you will be assigning to your points.
I hope, this helps.

Here is a complete example of what you wanted to achieve in pure JavaScript using only Highcharts library.
const chart = Highcharts.chart('container', {
chart: {
events: {
load () {
colorAllGray.call(this)
}
}
},
plotOptions: {
series: {
point: {
events: {
mouseOver(e) {
colorAllGray.call(chart)
e.target.update({
color: Highcharts.getOptions().colors[e.target.index]
})
},
mouseOut() {
colorAllGray.call(chart)
}
}
},
},
},
series: [{
type: 'pie',
name: 'Browser share',
innerSize: '50%',
data: [
['Firefox', 10.38],
['IE', 56.33],
['Chrome', 24.03],
['Safari', 4.77],
['Opera', 0.91], {
name: 'Proprietary or Undetectable',
y: 0.2,
dataLabels: {
enabled: false
}
}
]
}]
})
function colorAllGray() {
this.series[0].points.forEach(function(point) {
point.update({
color: 'rgba(150,100,50,0.1)'
})
})
}

How to do a data overlap independently column in Highcharts

I would like to have something similar to the image below, but the columns representing the classes all stack together now. How do I separate them and allow them to load dynamically as well?
Also I need a legend that says green is band 1, yellow is band 2, orange is band 3 and red is band 4, how do i do that as well? My code is in the JS Fiddle page. I am not allowed to use jQuery, need to use pure JavaScript.
var options = {
chart: {
renderTo : 'container',
type: 'column'
},
title: {
text: 'Topic & Subtopic Mastery'
},
subtitle: {
text: 'Average Level-Stream Mastery vs Average Class Mastery'
},
xAxis: {
categories: topics
},
yAxis: {
min: 0,
max: 100,
title: {
text: 'Mastery'
}
},
legend: {
layout: 'vertical',
backgroundColor: '#FFFFFF',
align: 'left',
verticalAlign: 'top',
x: 100,
y: 70,
floating: true,
shadow: true
},
tooltip: {
shared: true,
valueSuffix: ' %'
},
plotOptions: {
column: {
grouping: false,
shadow: false
}
},
series: resultsData
};
http://jsfiddle.net/kscwx139/2/

I came up with a solution you are looking for with specifying x and y axis data for level and giving appropriate width to the point.
$(function() {
var chart;
$(document).ready(function() {
var i = 0;
Highcharts.getOptions().colors = Highcharts.map(Highcharts.getOptions().colors, function(color) {
if (i == 0) {
i++;
return Highcharts.Color(color)
.setOpacity(1)
.get('rgba');
} else {
i++;
return Highcharts.Color(color)
.setOpacity(0.5)
.get('rgba');
}
});
var colors = Highcharts.getOptions().colors;
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'column',
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
borderColor: null
},
title: {
text: 'Mailboxes over Quota'
},
subtitle: {
text: 'Mailbox Size in MB'
},
exporting: {
enabled: false
},
credits: {
enabled: false
},
xAxis: {
categories: ["Overall Topic", "Topic 1", "Topic 2"],
title: {
text: null
}
},
yAxis: {
min: 0,
title: {
text: 'Total',
align: 'high'
},
allowDecimals: false,
},
tooltip: {
formatter: function() {
return '' +
this.series.name + ': ' + Highcharts.numberFormat(this.y, 0, '.', ',');
}
},
legend: {
enabled: true
},
credits: {
enabled: false
},
series: [{
name: 'Level',
color: colors[0],
data: [{
y: 86,
x: 0.25
}, {
y: 80,
x: 1.25
}, {
y: 95,
x: 2.25
}],
pointWidth: 80
}, {
name: '4A',
data: [90, 88, 97]
}, {
name: '4B',
data: [95, 78, 92]
}, {
name: '4C',
data: [80, 69, 84]
}]
});
});
});
To show in label inside your column you can use below code.
plotOptions: {
column: {
dataLabels: {
enabled: true,
formatter: function() {
return this.series.name;
},
y: 25,
}
}
}

highcharts, bar chart legend with verticalAlign top not working

i made a bar stacked chart using highcharts and i want the legend to be on top, i used the attribute verticalAlign with the value top but it didn't work !
here is my jsfiddle http://jsfiddle.net/rchod/sbtt6/
$(function () {
$('#container').highcharts({
chart: {
type: 'bar'
},
legend: {
align: 'right',
verticalAlign: 'top',
x: 0,
y: 100
},
credits: {
enabled: false
},
title: {
text: ''
},
xAxis: {
labels: {
enabled: false
},
categories: ['']
},
yAxis: {
labels: {
enabled: true
},
min: 0,
title: {
text: ''
}
},
legend: {
backgroundColor: '#FFFFFF',
reversed: true
},
tooltip: {
enabled: false
},
plotOptions: {
series: {
minPointLength: 3,
dataLabels: {
color: 'white',
align: 'center',
enabled: true,
format: '{y} %'
},
stacking: 'percent'
},
bar: {
events: {
legendItemClick: function () {
vote(1,this.userOptions.id);
return false;
}
}
,
showInLegend: true
}
},
series: [
{
name: 'yes',
data: [{ y : 73.91, id : '1' }],
id: '1'
},
{
name: 'no',
data: [{ y : 26.09, id : '2' }],
id: '2'
},
]
});
});

You have the legend property twice in your options. The 2nd one is overriding the first. Put them together:
legend: {
backgroundColor: '#FFFFFF',
reversed: true,
align: 'right',
verticalAlign: 'top',
x: 0,
y: 100
},
