Pre-creating chart objects based on templates - highcharts

Is it possible to wrap a highcharts chart in a function that uses templates to define the chart, pass the chart data in during the render process then render it to a div. Essentially, I need to pre-build a chart object and render it to a div at a specific time.

You can prepare a global json and use merge() function or push objects directly to template.
var template = {
chart: {
type: 'pie'
},
title: {
text: ''
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: true,
format: '<b>{point.name}</b>: {point.percentage:.1f} %',
style: {
color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black'
}
}
}
},
series: [{
data:[]
}]
};
template.title.text = 'Pie chart 1';
template.series[0].data = [['aaa1',3],['bbb1',4],['ccc1',5]];
$('#container1').highcharts(template);
template.title.text = 'Pie chart 2';
template.series[0].data = [['aaa2',3],['bbb2',4],['ccc2',5]];
$('#container2').highcharts(template);
Simple demo: http://jsfiddle.net/80fsL5x5/
var template = {
chart: {
type: 'pie'
},
title: {
text: ''
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: true,
format: '<b>{point.name}</b>: {point.percentage:.1f} %',
style: {
color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black'
}
}
}
},
series: [{
data:[]
}]
};
var options1 = {
title:{
text: 'Pie chart 1'
},
series:[{
data: [['aaa1',3],['bbb1',4],['ccc1',5]]
}]
};
$('#container1').highcharts(Highcharts.merge(template,options1));
var options2 = {
title:{
text: 'Pie chart 2'
},
series:[{
data: [['aaa2',3],['bbb2',4],['ccc2',5]]
}]
};
$('#container2').highcharts(Highcharts.merge(template,options2));

How to detect when dataLabels are overlapping and adjust them programmatically

I have a stacked column/scatter chart with some dataLabels off to one side. The issue I am facing is that when my two markers begin to get close to one another, their dataLabels overlap
I need to always show both labels, so is there a way to detect when labels are overlapping and move the bottom one down by adjusting its y value based on how much overlap there is?
sample fiddle of the issue
Highcharts.chart('container', {
chart: {
type: 'column',
width: 500
},
title: {
text: 'Stacked column chart'
},
xAxis: {
visible: false,
},
yAxis: {
min: 0,
visible: false,
title: {
},
},
legend: {
layout:"vertical",
align: "right",
verticalAlign: "bottom",
itemMarginTop: 15,
y: -10,
x: -50
},
tooltip: {
enabled: false,
},
plotOptions: {
scatter: {
marker: {
symbol: "triangle",
},
dataLabels: {
enabled: true,
x: -80,
y: 50,
allowOverlap: true,
useHTML: true,
}
},
column: {
pointWidth: 70,
stacking: 'normal',
dataLabels: {
enabled: false
}
}
},
series: [{
name: '',
data: [100],
color: "#ededed"
}, {
name: '',
data: [500]
}, {
name: '',
data: [400]
},
{
type: "scatter",
data: [1000],
color: "#000",
dataLabels: {
formatter: function(){
return "<div class='label-text'>Your goal of <br/>$"+ this.y +"<br/>text</div>"
},
}
},
{
type: "scatter",
data: [900],
color: "#000",
dataLabels: {
formatter: function(){
return "<div class='label-text'>You are here <br/>$"+ this.y +"<br/>text</div>"
},
}
}]
});
You can correct data-labels positions by using the attr method on their SVG elements.
For example:
chart: {
events: {
render: function() {
const series = this.series;
const dl1 = series[3].points[0].dataLabel;
const dl2 = series[4].points[0].dataLabel;
if (dl1.y + dl1.height > dl2.y) {
dl2.attr({
y: dl1.y + dl1.height
});
}
}
}
}

use abbreviated state names

I have a map of the US and its 600 x 400. How do I force it to use the Abbreviated State names which I see in the examples but am unable to reproduce in my own code.
I'm using the below code with some sample data to show the format of the code I'm passing. I'm having to parse the data out of a larger json response.
var data = [{"code":"AK","value":225}, {...} ];
This is the map:
$('#ha-worst-map-1').highcharts('Map', {

how do I get two highcharts on one page?

I have two charts that I am trying to load on separate div's on the same page, they are similar but one is a drill down and the other isn't. I have tried wrapping the entire function with var chart = $('#review').highcharts({ but it doesn't work.
The two charts are below:
$(function () {
var colors = Highcharts.getOptions().colors,
categories = ['Metric 1', 'Metric 2', 'Metric 3','metric 4'],
name = 'Votes',
data = [{
y: 1,
color: colors[0],
}, {
y: 2,
color: colors[1],
}, {
y: 3,
color: colors[2],
},{
y: 5,
color: colors[3],
}];
function setChart(name, categories, data, color) {
chart.xAxis[0].setCategories(categories, false);
chart.series[0].remove(false);
chart.addSeries({
name: name,
data: data,
color: color || 'white'
}, false);
chart.redraw();
}
var chart = $('#review').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Review breakdown'
},
xAxis: {
categories: categories
},
tooltip: {
formatter: function() {
var point = this.point,
s = this.x +'<br><b>'+ this.y +' stars</b><br/>';
return s;
}
},
series: [{
name: name,
data: data,
color: 'white'
}],
exporting: {
enabled: false
},
legend: {
enabled: false
},
credits: {
enabled: false
}, yAxis: {min: 0, max: 5,
title: {text: 'Star Rating'}
}
})
.highcharts(); // return chart
});
$(function () {
var colors = Highcharts.getOptions().colors,
categories = ['positive', 'negative', 'sum'],
name = 'Votes',
data = [{
y: 55.11,
color: colors[0],
drilldown: {

drilldown: {
name: 'Negative votes',
categories: ['Users', 'Admin', 'Anonymous'],
data: [-4.55, -1.42, -0.23],
color: colors[3]
}
}, {
y: 2.14,
color: colors[4],
drilldown: {
name: 'Total votes',
categories: ['Users', 'Admin', 'Anonymous'],

chart.xAxis[0].setCategories(categories, false);
chart.series[0].remove(false);
chart.addSeries({

data: data,
color: color || 'white'
}, false);
chart.redraw();
}
var chart = $('#votes').highcharts({

},
title: {

},

text: 'Click the columns to view breakdown.'
},

}
},

If you're trying to get two charts on one page then it is VERY simple.
<div id="chart-A" class="chart"></div>
<div class="spacer"></div>
<div id="chart-B" class="chart"></div>
CSS - Just to make the example a little easier on the eyes
.chart {
height: 200px;
}
.spacer {
height: 20px;
}
JavaScript
$(function() {
// If you need to specify any global settings such as colors or other settings you can do that here
// Build Chart A
$('#chart-A').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Chart A'
},
xAxis: {
categories: ['Jane', 'John', 'Joe', 'Jack', 'jim']
},
yAxis: {
min: 0,
title: {
text: 'Apple Consumption'
}
},
legend: {
enabled: false
},
credits: {
enabled: false
},
tooltip: {
shared: true
},
series: [{
name: 'Apples',
data: [5, 3, 8, 2, 4]
}]
});
// Build Chart B
$('#chart-B').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Chart B'
},
xAxis: {
categories: ['Jane', 'John', 'Joe', 'Jack', 'jim']
},
yAxis: {
min: 0,
title: {
text: 'Miles during Run'
}
},
legend: {
enabled: false
},
credits: {
enabled: false
},
tooltip: {
shared: true
},
series: [{
name: 'Miles',
data: [2.4, 3.8, 6.1, 5.3, 4.1]
}]
});
});
Here's a JSFiddle: http://jsfiddle.net/engemasa/7cvCX/
I am not really sure what some of your code is trying to do - seems a little needlessly complicated, FWIW
AS to how to make multiple charts on the same page - you do it just like you would make one chart on a page, just do it more than once :)
and make sure you have different container element ids - otherwise you are just overwriting one chart with the next.
One example of multiple charts on a page:
