ApexCharts: radar chart fill and stroke

Using ApexCharts, I have the following options
this.chartOptions = {
xaxis: {
labels: {
show: true,
style: {
fontSize: '12px',
fontWeight: 700
},
},
},
yaxis: {
show: false
},
series: [
{
data: [8, 7, 10, 8, 16, 9, 10, 5]
},
{
data: [9, 15, 10, 10, 15, 11, 14, 10]
},
{
data: [8, 15, 9, 10, 15, 11, 13, 10]
},
]
chart: {
type: 'radar',
toolbar: {
show: false
}
},
markers: {
size: 0,
strokeWidth: 0
},
fill: {
colors: ['#157FF8', '#16B264', '#FF576F']
},
stroke: {
show: true,
width: [6, 1, 1],
colors: ['#157FF8', 'transparent', 'transparent']
},
plotOptions: {
radar: {
polygons: {
fill: {
colors: ['#fff']
}
}
}
},
legend: {
show: false
}
};
I would expect that the strokes of my graphs would be 6 for the first series and 1 for the next two, but they're all 6.
How do I set the stroke widths of a radar chart with multiple data entries?

Group data by weekdays in Highchart

I'm plotting a graph that needs to combine data of a selected date range to weekdays i mean if i selected a date range from ex: 2021-05-01 to 2021-05-31 in that consider 2021-05-01,2021-05-08,2021-05-15 these days are Friday so i need to combine datas of these dates and show as one data with label friday. With the current options that i used the chart is plotting like this. Is there any ways to display it correctly.
Demo Fiddle
This is the way that i currently getting the result
This is the result that i'm expecting
These are the current configd that i'm using in the highchart.

You can make a special function to do this sorting by using Array.map() and Array.filter() methods:
const categories = [

Simply use Renderer.image to add an image on a chart. You can do that for example on load event.

Highchart data does not start with 0 gives error

I recently encountered a weird issue with HighStock.
Firstly here is my code http://jsfiddle.net/woon123/br0e8mkw/
$(document).ready(function () {
Highcharts.setOptions({
global: {
useUTC: false
}
});
$('#analytics_line').highcharts('StockChart', {
credits: {
enabled: false
},
title: {
text: 'Analytics of Deals'
},
subtitle: {
text: 'View Count and Redemption Count'
},
rangeSelector: {
allButtonsEnabled: true,
buttons: [{
type: 'month',
count: 3,
text: 'Day',
dataGrouping: {
forced: true,
units: [
['day', [1]]
]
}
}, {
type: 'year',
count: 1,
text: 'Week',
dataGrouping: {
forced: true,
units: [
['week', [1]]
]
}
}],
buttonTheme: {
width: 60
},
},
yAxis: {
floor: 0,
title: {
text: 'Number'
}
},
plotOptions: {
dataLabels: {
visible: true
},
series: {
compare: 'value'
}
},
tooltip: {
pointFormat: '<span style="color:{series.color}">{series.name}</span>: <b>{point.y}</b><br/>',
valueDecimals: 2
},
legend: {
enabled: true,
align: 'right',
backgroundColor: '#FCFFC5',
borderColor: 'black',
borderWidth: 2,
layout: 'vertical',
verticalAlign: 'top',
y: 100,
shadow: true
},
series: [{
id: "First Graph",
name: "First Graph",
pointStart: 1444060800000.0,
pointInterval: 24 * 3600 * 1000,
data: [20, 23, 23, 23, 23, 23, 23, 23, 23, 23],
}, {
id: "Second Graph",
name: "Second Graph",
pointStart: 1444060800000.0,
pointInterval: 24 * 3600 * 1000,
data: [9, 12, 16, 16, 16, 16, 16, 16, 16, 16],
}, ]
}, function (chart) {
// apply the date pickers
setTimeout(function () {
$('input.highcharts-range-selector', $(chart.container).parent())
.datepicker();
}, 0);
});
// Set the datepicker's date format
$.datepicker.setDefaults({
dateFormat: 'yy-mm-dd',
onSelect: function () {
this.onchange();
this.onblur();
}
});
});
In this case, First Graph is suppose to be above Second Graph according to the data. When you compare the series, First Graph values are always higher then Second Graph.
However, the graph plotted actually cause First Graph to be below Second graph although when you mouse over the lines, it gives the correct values.
Furthermore, First Graph is suppose to start at 20 but as you can see it starts at 0, and the Y-axis values are wrong as well (0-2.5-5)
However, all these errors can be solved by placing 0 at the start of the data.
For the case of First Graph it is [0, 20, 23, 23, 23, 23, 23, 23, 23, 23, 23] and Second Graph it is [0, 9, 12, 16, 16, 16, 16, 16, 16, 16, 16].
Can anyone advice why is this the case and perhaps provide a solution to allow my data to start with a positive integer rather then 0

Take out the compare on the plotOptions, series
series: {
compare: 'value'
}
Fiddle: http://jsfiddle.net/br0e8mkw/2/
From the API: http://api.highcharts.com/highstock#plotOptions.series.compare
Compare the values of the series against the first value in the visible range. The y axis will show percentage or absolute change depending on whether compare is set to "percent" or "value". When this is applied to multiple series, it allows comparing the development of the series against each other. Defaults to undefined.

Button to show all legend items in highcharts

Thanks to this helpful post, I was able to re-format the legend so that clicking a legend item shows only that item, rather than hiding it and showing all other items.
Once the user clicks on a legend item, I'd like for the user to be able to click a button and once again see all of the legend items.
Here's the fiddle: http://jsfiddle.net/scheltense/qb13g51u/1/
And the code:
$(function () {
$('#container').highcharts({

}, function (chart) {
var point = chart.series[0].data[8],

'*through Aug. 5, 2014',
point.plotX + chart.plotLeft - 280,
point.plotY + chart.plotTop + 316
).attr({
zIndex: 5
})
.css({
color: '#909090',
fontSize: '10px'
})
.add(),
box = text.getBBox();
});
});
This is the portion of the code that shows only the legend item that has been clicked:
plotOptions: {
area: {
events:
{
legendItemClick: function(event)
{
var seriesIndex = this.index;
var series = this.chart.series;
for (var i = 0; i < series.length; i++)
{
if (series[i].index != seriesIndex)
{
series[i].hide();
}
else
{
series[i].show();
}
}
return false;
}
},
This is my first JavaScript project, so I apologize if the question is unclear, and I appreciate any help that can be provided.
Thanks very much.

The series object has a show() function (http://api.highcharts.com/highcharts#Series.show).
Assuming your button has an id of showall:
$('#showall').on('click', function() {
var series = $('#container').highcharts().series;
for(i=0;i<series.length;i++) {
if (!series[i].visible) series[i].show();
}
});
