Is it possible to have the same feature that you get in Apache echarts. Refer to the following Apache echarts example in JS snippet, where the legend given by type:"piecewise" allows the user to hide on click particular color values. How can i get the same thing in Highcharts. The usual heatmap shows a bar legend, but I want the conventional legend that you see in line or bar charts. Thanks.
var chartDom = document.getElementById('main');
var myChart = echarts.init(chartDom);

Yes, it is possible with Highcharts. You need to only use data-classes in color-axis settings.
colorAxis: {
dataClasses: [{
from: 0,
to: 50
}, {
...
}, {
...
}],
...
}

Following the demo example for the heatmap chart,

the series name doesnt show up for me, what am i missing?
series: [{

After consulting the topic in comments below the question, you can set your series name as Axis.title inside of Chart.events.load event function, using setTitle() method. Then it should be dynamically set at every chart load basing on your current series name. Here is the code which shows how to achieve it:
chart: {
events: {
load() {
var chart = this
var seriesName = chart.series[0].name
chart.xAxis[0].setTitle({ text: seriesName, style: { fontWeight: 'bold' } })
}
}
}

I am currently struggling with my Highcharts chart with the hours format. I have a series with 65 points of data but the hour format of each point is 24 hours. I am unable to use the same format in the highchart and it automatically converts for example 13:00:00 to 01:00:00.
Here is my script
<script>
Highcharts.setOptions({ global: { timezoneOffset: 660, useUTC: true } });
var chart1;
$(document).ready(function() {
chart1 = new Highcharts.StockChart({
chart: { renderTo:'chart1_container', type: 'spline' },

subtitle: { text: 'Y1' },
title: { text: 'Y1' },
tooltip: { enabled: true, formatter: function() {var s = [];$.each(this.points, function(i, point) {s.push('<span style="color:'+point.series.color+';font-weight:bold;">'+ point.series.name +' : '+point.y + '<span>'); });return s.join(' and ');}, shared: true },
xAxis: { dateTimeLabelFormats: { hour: '%H:%M', day: '%H:%M' }, type: 'datetime' },
yAxis: { title: { text: 'Y1' } },
series: [{ data: [[Date.parse('09/01/2016 12:45:34'), 0], [Date.parse('09/01/2016 12:46:11'), 0], [Date.parse('09/01/2016 12:47:24'), 0], [Date.parse('09/01/2016 12:48:59'), 0], [Date.parse('09/01/2016 12:50:41'), 1], [Date.parse('09/01/2016 12:51:43'), 1], [Date.parse('09/01/2016 12:52:01'), 1], [Date.parse('09/01/2016 12:55:14'), 1], [Date.parse('09/01/2016 13:01:12'), 1], [Date.parse('09/01/2016 13:01:30'), 1], [Date.parse('09/01/2016 13:02:37'), 1], [Date.parse('09/01/2016 13:03:31'), 1], [Date.parse('09/01/2016 13:04:19'), 1], [Date.parse('09/01/2016 13:05:14'), 1], [Date.parse('09/01/2016 13:05:32'), 1], [Date.parse('09/01/2016 13:06:52'), 1], [Date.parse('09/01/2016 13:07:47'), 1], [Date.parse('09/01/2016 13:08:06'), 1], [Date.parse('09/01/2016 13:09:01'), 1], [Date.parse('09/01/2016 13:10:14'), 1], [Date.parse('09/01/2016 13:12:27'), 2], [Date.parse('09/01/2016 13:13:15'), 2], [Date.parse('09/01/2016 13:14:03'), 2], [Date.parse('09/01/2016 13:14:40'), 2], [Date.parse('09/01/2016 13:15:35'), 2], [Date.parse('09/01/2016 13:16:30'), 2], [Date.parse('09/01/2016 13:17:55'), 2], [Date.parse('09/01/2016 13:18:21'), 2], [Date.parse('09/01/2016 13:21:30'), 2], [Date.parse('09/01/2016 13:23:58'), 3], [Date.parse('09/01/2016 13:26:39'), 3], [Date.parse('09/01/2016 13:29:18'), 4], [Date.parse('09/01/2016 13:30:14'), 4], [Date.parse('09/01/2016 13:31:29'), 4], [Date.parse('09/01/2016 13:32:36'), 4], [Date.parse('09/01/2016 13:34:10'), 4], [Date.parse('09/01/2016 13:36:39'), 5], [Date.parse('09/01/2016 13:39:01'), 5], [Date.parse('09/01/2016 13:39:38'), 5], [Date.parse('09/01/2016 13:40:46'), 5], [Date.parse('09/01/2016 13:42:01'), 6], [Date.parse('09/01/2016 13:43:09'), 6], [Date.parse('09/01/2016 13:45:32'), 6], [Date.parse('09/01/2016 13:46:59'), 7], [Date.parse('09/01/2016 13:48:26'), 7], [Date.parse('09/01/2016 13:49:04'), 7], [Date.parse('09/01/2016 13:50:11'), 7], [Date.parse('09/01/2016 13:51:46'), 8], [Date.parse('09/01/2016 13:55:18'), 8], [Date.parse('09/01/2016 13:56:04'), 8], [Date.parse('09/01/2016 13:59:37'), 9], [Date.parse('09/01/2016 14:02:25'), 10], [Date.parse('09/01/2016 14:08:38'), 11], [Date.parse('09/01/2016 14:12:13'), 12], [Date.parse('09/01/2016 14:13:12'), 12], [Date.parse('09/01/2016 14:15:58'), 13], [Date.parse('09/01/2016 14:19:44'), 14], [Date.parse('09/01/2016 14:20:35'), 14], [Date.parse('09/01/2016 14:20:55'), 14], [Date.parse('09/01/2016 14:21:53'), 14], [Date.parse('09/01/2016 14:22:52'), 14], [Date.parse('09/01/2016 14:23:51'), 15], [Date.parse('09/01/2016 14:24:30'), 15]], name: 'Y1' }]

Highcharts is not converting 13:00:00 to 01:00:00. You are using default 24-hour date time Highcharts/Highstock format. You just do not have a data point with such date that would show with a time after 12 PM, because of your timezoneOffset and other chart's settings.
Example with an extra data point: http://jsfiddle.net/68xay5jb/
for 24 hour formate try to do like below with Date.UTC
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container'
},
xAxis: {
type: 'datetime' //ensures that xAxis is treated as datetime values
},
series: [{
data: [
[Date.UTC(2012, 5, 22, 8, 15), 14.8],
[Date.UTC(2012, 5, 22, 8, 20), 13.9],
[Date.UTC(2012, 5, 22, 8, 25), 12.8]
//and so on...
]
}]
});
I am trying to adapt a highcharts heatmap from raw coding to the Yii2 plugin by Milos Schuman. Area and line charts are working but there is not an example of using heatmap and I tried almost everything.
This is the code as shown in highcharts demo:
$(function () {
$('#container').highcharts({
chart: {
type: 'heatmap',
},
title: {
text: 'Sales per employee per weekday'
},
xAxis: {
categories: ['Alexander', 'Marie', 'Maximilian', 'Sophia', 'Lukas', 'Maria', 'Leon', 'Anna', 'Tim', 'Laura']
},
yAxis: {
categories: ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday'],
},
series: [{
name: 'Sales per employee',
borderWidth: 1,
data: [[0, 0, 10], [0, 1, 19], [0, 2, 8], [0, 3, 24], [0, 4, 67], [1, 0, 92], [1, 1, 58], [1, 2, 78], [1, 3, 117], [1, 4, 48], [2, 0, 35], [2, 1, 15], [2, 2, 123], [2, 3, 64], [2, 4, 52], [3, 0, 72], [3, 1, 132], [3, 2, 114], [3, 3, 19], [3, 4, 16], [4, 0, 38], [4, 1, 5], [4, 2, 8], [4, 3, 117], [4, 4, 115], [5, 0, 88], [5, 1, 32], [5, 2, 12], [5, 3, 6], [5, 4, 120], [6, 0, 13], [6, 1, 44], [6, 2, 88], [6, 3, 98], [6, 4, 96], [7, 0, 31], [7, 1, 1], [7, 2, 82], [7, 3, 32], [7, 4, 30], [8, 0, 85], [8, 1, 97], [8, 2, 123], [8, 3, 64], [8, 4, 84], [9, 0, 47], [9, 1, 114], [9, 2, 31], [9, 3, 48], [9, 4, 91]],
dataLabels: {
enabled: true,
color: '#000000'
}
}]
});
});
And a sample of Area chart using the Yii2 widget:
use miloschuman\highcharts\Highcharts;
echo Highcharts::widget([
'options' => [
'title' => ['text' => 'Fruit Consumption'],
'xAxis' => [
'categories' => ['Apples', 'Bananas', 'Oranges']
],
'yAxis' => [
'title' => ['text' => 'Fruit eaten']
],
'series' => [
['name' => 'Jane', 'data' => [1, 0, 4]],
['name' => 'John', 'data' => [5, 7, 3]]
]
]
]);
The problem basically is that in case of a heatmap chart it is required to specify that the heatmap module is needed before the options description like that:
'scripts' => [
'modules/heatmap', // adds heatmap support
],
That is a working sample based on the highcharts demo:
$heatmap_options = [
'scripts' => [
'modules/heatmap', // adds heatmap support
],
'options' => [
'title' => ['text' => 'Sales per employee per weekday'],
'chart' => [
'type' => 'heatmap'
],
'xAxis' => [
'categories' =>['Alexander', 'Marie', 'Maximilian', 'Sophia', 'Lukas', 'Maria', 'Leon', 'Anna', 'Tim', 'Laura']
],
'yAxis' => [
'categories' => ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday']
],
'colorAxis' =>[
],
'series' => [[
'name' => 'Sales per employee',
'borderWidth' => 1,
'data' => [[0, 0, 10], [0, 1, 19], [0, 2, 8], [0, 3, 24], [0, 4, 67], [1, 0, 92], [1, 1, 58], [1, 2, 78], [1, 3, 117],
[1, 4, 48], [2, 0, 35], [2, 1, 15], [2, 2, 123], [2, 3, 64], [2, 4, 52], [3, 0, 72], [3, 1, 132], [3, 2, 114],
[3, 3, 19], [3, 4, 16], [4, 0, 38], [4, 1, 5], [4, 2, 8], [4, 3, 117], [4, 4, 115], [5, 0, 88], [5, 1, 32], [5, 2, 12],
[5, 3, 6], [5, 4, 120], [6, 0, 13], [6, 1, 44], [6, 2, 88], [6, 3, 98], [6, 4, 96], [7, 0, 31], [7, 1, 1], [7, 2, 82],

I want to have a chart that reminds the very 3d. I can do only with colors and gradients. It would be very important to add another properties at the "frame" (on top), because in that way i coulde use other colors and gradients...
But is impossible.
The yAxis is reversed, because in future on bottom (that with yaxis reversed is at the top) i will add an image...
But on bottom there will be nothing....
So, i would like to add a column in my scatter chart. But i want that the only column must be at the bottom e in the chart (now the column is at the top and half outside of chart)...
Is possible ?
Maybe another solution could be to add a rect ? but the problem is that my chart is scatter type and draggable.
Thanks
