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
}, {
...
}, {
...
}],
...
}

i want to use list (not set) with different items.but its not working if it not constains to add item,
void main() {
List<List<int>> mylistint=[[1, 2, 5, 10],[1, 3],[1, 2, 19, 38],[1, 3],[1, 2, 5, 10],[1, 3],[1, 2, 19, 38],[1, 3]];
List<List<int>> listeddiffintlist(List<List<int>> list){
List<List<int>> returnlist=[];
for(var i=0;i<list.length;i++){
if(!returnlist.contains(list[i])){ //not working if contains it add also
returnlist.add(list[i]);
}
}
return returnlist;
}
List<List<int>> returnlist = listeddiffintlist( mylistint);
print (returnlist.toString());
//expected=> [[1, 2, 5, 10],[1, 3],[1, 2, 19, 38]]
// result=> [[1, 2, 5, 10], [1, 3], [1, 2, 19, 38], [1, 3], [1, 2, 5, 10], [1, 3], [1, 2, 19, 38], [1, 3]] more than 1 it contains [1, 3] or someone
}
contains are just using the == operator on the elements. Since lists in Dart does not implement the == operator, two lists is only equal if they are the same instance in memory. If you want to compare based on the content of the lists, you need to do that yourself or use a package for it.
In your example you can do something like this:
void main() {
List<List<int>> mylistint = [
[1, 2, 5, 10],
[1, 3],
[1, 2, 19, 38],
[1, 3],
[1, 2, 5, 10],
[1, 3],
[1, 2, 19, 38],
[1, 3]
];
List<List<int>> listeddiffintlist(List<List<int>> list) {
List<List<int>> returnlist = [];
for (var i = 0; i < list.length; i++) {
if (!returnlist.any((returnSubLists) =>
list[i].every((element) => returnSubLists.contains(element)))) {
returnlist.add(list[i]);
}
}
return returnlist;
}
List<List<int>> returnlist = listeddiffintlist(mylistint);
print(returnlist.toString()); // [[1, 2, 5, 10], [1, 3], [1, 2, 19, 38]]
}
Alternative, you can use the collection package where the ListEquality can be used:
import 'package:collection/collection.dart';
void main() {
List<List<int>> mylistint = [
[1, 2, 5, 10],
[1, 3],
[1, 2, 19, 38],
[1, 3],
[1, 2, 5, 10],
[1, 3],
[1, 2, 19, 38],
[1, 3]
];
List<List<int>> listeddiffintlist(List<List<int>> list) {
List<List<int>> returnlist = [];
for (var i = 0; i < list.length; i++) {
if (!returnlist.any(
(subList) => const ListEquality<int>().equals(subList, list[i]))) {
returnlist.add(list[i]);
}
}
return returnlist;
}
List<List<int>> returnlist = listeddiffintlist(mylistint);
print(returnlist.toString()); // [[1, 2, 5, 10], [1, 3], [1, 2, 19, 38]]
}
The last solution could also be shorten down to:
import 'package:collection/collection.dart';
void main() {
final myListInt = [
[1, 2, 5, 10],
[1, 3],
[1, 2, 19, 38],
[1, 3],
[1, 2, 5, 10],
[1, 3],
[1, 2, 19, 38],
[1, 3]
];
final returnList = myListInt.fold<List<List<int>>>([], (result, b) {
if (!result.any((a) => const ListEquality<int>().equals(a, b))) {
result.add(b);
}
return result;
}).toList();
print(returnList); // [[1, 2, 5, 10], [1, 3], [1, 2, 19, 38]]
}
Or (if you want to make a very short solution which are not that readable):
import 'package:collection/collection.dart';
void main() {
final myListInt = [
[1, 2, 5, 10],
[1, 3],
[1, 2, 19, 38],
[1, 3],
[1, 2, 5, 10],
[1, 3],
[1, 2, 19, 38],
[1, 3]
];
final returnList = myListInt.fold<List<List<int>>>(
[],
(result, b) => !result.any((a) => const ListEquality<int>().equals(a, b))
? (result..add(b))
: result).toList();
print(returnList); // [[1, 2, 5, 10], [1, 3], [1, 2, 19, 38]]
}
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],
[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,

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
In a stacked chart with a data series in the format of [x, y] there is a larger margin on the left and on the right side. I have created the following jsfiddle to with sample data:

I have tried with min and max values, categories, etc. and nothing worked out. How can I adjust the chart to be displayed in full size?
I have updated the code and the jsfiddle with the proper sorting. I was using 3.0 and not 3.05 therefore I had no errors in the console. With the latest version I have to issues remaining. One is the above mentioned large margin at the right and left side and the other one is i am unable (even with tickInterval) to have a tick per calendar week. Based on the above mentioned sample the entire chart should have the range from x=11 to x=34 with a tick on each x.
The problem is with calculated pointRange for first series - when you have only two points, for x=11 and x=31 it is assumed that minimum interval between points in that series is 20, so Highcharts will try to set interval something about 20. For such cases you need to use pointRange for example set it to 1, see: http://jsfiddle.net/ymyrA/5/
