Echart icon in series tooltip

So i have the following configuration:
const frequencyChartoption = {
title: {},
tooltip: {},
legend: {
data: ['Frekvens', 'Vigtighed']
},
xAxis: {
type: 'category',
data: ['marker_01', 'marker_02'],
axisLabel: {
formatter: function (value) {
return '{' + value + '| }\n{value|}';
},
margin: 20,
rich: {
value: {
lineHeight: 30,
align: 'center'
},
marker_01: {
height: 20,
align: 'center',
backgroundColor: {
image: icons.marker_01
}
},
marker_02: {
height: 20,
align: 'center',
backgroundColor: {
image: icons.maker_02
}
},
}
}
},
yAxis: {},
series: [{
name: 'Frekvens',
type: 'bar',
data: frequencyChartFrequencyScore,
tooltip: icons.marker_01,
itemStyle: {
normal: {
color: colors[0],
label: {
interval: 5,
show: true,
position: 'top',
formatter: '\n{c}'
}
}
}
},
{
name: 'Vigtighed',
type: 'bar',
data: frequencyChartImportance,
itemStyle: {
normal: {
color: colors[1],
label: {
show: true,
position: 'top',
formatter: '\n{c}'
}
}
}
}
]
};
Now as you can see i am using two images as my xAxis
Now i wish to make these show up on my tooltip when i hover over the chart. However i am not quite sure how to do that and was hoping some of you might be able to help?

Simply stated, a series may have a tooltip but the tooltip must be listed as an object with an identifying trigger (see tooltip documentation).
series: [{
name: 'Frekvens',
type: 'bar',
data: frequencyChartFrequencyScore,
tooltip: {
show: true,
trigger: 'axis',
formatter: (params) => {
// see tooltip.formatter for details
// you want to focus on the 'marker' property
return params[0].name;
}
}
}]
With this in mind, you can set two variables and print them as need be within the output of your tooltip. See the additional example below (from CodePen).
var myChart = echarts.init(document.getElementById("main"));
// specify chart configuration item and data
var option = {
title: {
text: "ECharts entry example"
},
tooltip: {
show: true,
trigger: "axis",
backgroundColor: 'rgba(0, 0, 0, 0.8)',
formatter: (params) => {
// create new marker
var icon0 = `<span data-tooltip="minimum" style="border-left: 2px solid #fff;display: inline-block;height: 12px;margin-right: 5px;width: 20px;"><span style="background-color:${params[0].color};display: block;height: 4px;margin-top: 4px;width: 20px;"></span></span>`;
var icon1 = `<span data-tooltip="implied-high" style="background-color:rgba(255,255,255,.75);border-radius: 2px;display: inline-block;height: 12px;margin-right:5px;width: 20px;"><span style="background-color:${params[0].color};border: 1px solid ${params[0].color};border-radius:50%;display:block;height:6px;margin-left:7px;margin-top:3px;width:6px;"></span></span>`;
console.log("params", params, params[0].name);
return `${icon0} ${params[0].name}
${icon1} ${params[0].value}`;
},
textStyle: {
fontWeight: 'bold',
fontSize: 18
}
},
legend: {
data: ["Sales"]
},
xAxis: {
data: ["shirt", "cardign", "chiffon shirt", "pants", "heels", "socks"]
},
yAxis: {},
series: [
{
name: "Sales",
type: "bar",
data: [5, 20, 36, 10, 10, 20]
}
]
};
// use configuration item and data specified to show chart
myChart.setOption(option);

how to show Y axis (not it label) in jquery?

I am using highchart with jquery .I am able to show X-axis with label (Apple,pears)..But I want to show Y-axis without lable .In other words I want to show a straight line on Y-axis.
here is my code
http://jsfiddle.net/3sembmfo/118/
$(function () {
// Configure the chart
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Highcharts axis visibility'
},
xAxis: {
categories: ['Apples', 'Pears', 'Oranges', 'Peaches']
},
yAxis: {
allowDecimals: false,
title: {
text: 'Fruit'
},
visible: false
},
plotOptions: {
series: {
stacking: 'normal',
dataLabels: {
enabled: true
}
}
},
series: [{
data: [1, 3, 2, 4],
name: 'Ola'
}, {
data: [5, 4, 5, 2],
name: 'Kari'
}]
});
var yVis = false,
xVis = true;
});

This can, and should, be resolved by options:
yAxis.lineWidth - to enable the line
yAxis.title.text - to hide the title
yAxis.gridLineWidth - to disable horizontal lines,
yAxis.labels.enabled - to disable labels
Working demo: http://jsfiddle.net/BlackLabel/3sembmfo/122/
Snippet:
yAxis: {
allowDecimals: false,
title: {
text: null
},
labels: {
enabled: false
},
gridLineWidth: 0,
lineWidth: 1,
visible: true
},

Replace your y Axis code with this. http://jsfiddle.net/3sembmfo/119/. If you have any query let me know.
yAxis: {
allowDecimals: false,
labels:{
style: {
fontSize:'0px'
}
},
title: {
text: 'Fruit',
style: {
fontSize:'0px'
}
},
visible: true
},

You have to use Highcharts.SVGRenderer and add line using load event.
chart: {
type: 'column',
events: {
load: function() {
var ren = this.renderer;
ren.path(['M', 10, 10, 'L', 10, this.chartHeight * .8])
.attr({
'stroke-width': 1,
stroke: '#000'
})
.add();
}
}
},
Fiddle demo
$(function() {
// Configure the chart
$('#container').highcharts({
chart: {
type: 'column',
events: {
load: function() {
var ren = this.renderer;
ren.path(['M', 10, 10, 'L', 10, this.chartHeight * .8])
.attr({
'stroke-width': 1,
stroke: '#000'
})
.add();
}
}
},
title: {
text: 'Highcharts axis visibility'
},
xAxis: {
categories: ['Apples', 'Pears', 'Oranges', 'Peaches'],
},
yAxis: {
allowDecimals: false,
title: {
text: ''
},
labels: {
enabled: false
},
gridLineWidth: 0,
},
plotOptions: {
series: {
stacking: 'normal',
dataLabels: {
enabled: true
}
}
},
series: [{
data: [1, 3, 2, 4],
name: 'Ola'
}, {
data: [5, 4, 5, 2],
name: 'Kari'
}]
});
var yVis = false,
xVis = true;
});
#container {
min-width: 300px;
max-width: 800px;
height: 300px;
margin: 1em auto;
}

Highcharts how to make the y axis series value return only 2 decimal places

I want to make the format of my y axis series to only return 2 decimal places.
I have this code:
$('#main-graph').highcharts({
chart:{
zoomType:'xy',
type: 'spline'
},
title: {
text: '',
x: -20 //center
},
xAxis: {
categories: stat_date,
crosshair:true,
},
yAxis: [
{ //0
title: {
text: 'Impressions'
},
},
{//1
title:{
text: "Clicks"
}
},
{ //2
title:{
text: "CTR"
}
},
{ //3
title:{
text: "CPM"
}
},
{ //4
title:{
text: "CPC"
}
},
{ //5 - secondary axis which is the SPEND axis
title: {
text: "Spend",
style:{
// color: Highcharts.getOptions().colors[0]
color: "#8B8B8B"
}
},
opposite:true
}],
tooltip: {
shared: true,
valueDecimals: 2
// pointFormat: "{point.y:,.2f}"
},
legend: {
layout: 'horizontal',
align: 'top',
verticalAlign: 'top',
borderWidth: 0,
floating:true,
x: 0,
y: 0
},
series: [{
name: 'Spend',
data: spend,
yAxis: 5,
type:'column'
}, {
name: 'Impressions',
data: imp,
yAxis: 0,
}, {
name: 'Clicks',
data: clicks,
yAxis: 1
},
{
name: 'CTR',
data: ctr,
yAxis: 2
}, {
name: 'CPM',
data: cpm,
yAxis: 3
}, {
name: 'CPC',
data: cpc,
yAxis: 4
}
]
});
}
I tried adding this line of code:
dataLabels: {
enabled: true,
formatter: function () {
return Highcharts.numberFormat(this.y,2);
}
}
but it isn't working.
Any ideas? your help will be grealty apprecaited!
Thanks!

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,
}
}
}
You can see it in action at this JSFIddle

Plot always starts at 0, highstock spline chart

I have data like this
var data = [];
for(var i=1;i<201;i++){
data.push([i,(Math.random() * (80 - 40 + 1)) + 40])
}
And I'm creating chart like this:
$('.reactivityCont').highcharts('StockChart', {
chart: {
marginTop: 140
},
credits: {
enabled: false
},
rangeSelector : {
selected : 1
},
scrollbar: {
enabled: false
},
navigator: {
top : 40,
xAxis: {
labels: {
formatter: function() {
return this.value;
}
}
}
},
xAxis: {
labels: {
y: 50,
formatter: function() {
return this.value;
}
},
events: {
setExtremes: function (e) {
start = parseInt(e.min);
koniec = parseInt(e.max);
$('.nt').hide();
for(var i = start-1;i<koniec;i++){
$('.nt').eq(i).show();
}
main();
}
}
},
series : [{
type: 'column',
name : 'reactivity',
data : data,
showInLegend: false,
tooltip: {
valueDecimals: 2
}
},
{type: 'spline',
name: 'experiment 1',
data: data2,
color: 'green',
visible: false,
tooltip: {
valueDecimals: 2
}
},
{type: 'spline',
name: 'experiment 2',
data: data3,
color: 'red',
visible: false,
tooltip: {
valueDecimals: 2
}
}
],
legend :{
enabled: true,
margin: 0
},
rangeSelector : {
buttons: [
{
type: 'millisecond',
count: seqLength/5,
text: '0.25'
}, {
type: 'millisecond',
count: seqLength/3,
text: '0.3'
}, {
type: 'millisecond',
count: seqLength/2,
text: '0.5'
}, {
type: 'all',
text: '1.0'
}
],
inputEnabled: false, // it supports only days
selected : 4 // all
}
});
But unfortunately, my plot starts with 0, but it should not, because there is no such a value.
I tried fix it, e. g. by setting plotOptions:pointStart but that didn't work.

This is caused by using column type series, where columns always starts from 0. To prevent this set threshold: null, like this:
series : [{
type: 'column',
threshold: null,
...
}]

You can use theXAxis's min param.
For Example.
xAxis: {
labels: {
formatter: function() {
return this.value;
}
},
min: myInitValue,
max: myEndValue
}
Hope It Helps.
