Using matter-js when adding a Body using fromVertices - the resulting vertices are not positioned correctly with relation to each other

Here's the shape I'm expecting to see. You can see the points along the edge depicting the vertices.
Here's the json file (generated from the above) that I'm loading in (via a simple import) and using to create the Body.
{
"cannon_transparent_sm": {
"label": "cannon",
"density": 0.1,
"restitution": 0,
"friction": 0.1,
"frictionAir": 0.01,
"frictionStatic": 0.5,
"fixtures": [
{
"label": "cannon_fixture",
"vertices": [
[ { "x":150, "y":45 }, { "x":134, "y":0 }, { "x":18, "y":30 }, { "x":1, "y":56 }, { "x":21, "y":94 }, { "x":86, "y":76 } ],
[ { "x":43, "y":17 }, { "x":44, "y":23 }, { "x":59, "y":19 }, { "x":58, "y":14 } ],
[ { "x":6, "y":41 }, { "x":1, "y":56 }, { "x":18, "y":30 } ],
[ { "x":6, "y":83 }, { "x":21, "y":94 }, { "x":1, "y":56 }, { "x":2, "y":72 } ],
[ { "x":86, "y":76 }, { "x":21, "y":94 }, { "x":25, "y":108 }, { "x":48, "y":124 }, { "x":61, "y":124 }, { "x":73, "y":119 }, { "x":83, "y":109 }, { "x":88, "y":95 } ],
[ { "x":34, "y":118 }, { "x":48, "y":124 }, { "x":25, "y":108 } ]
]
}
]
}
}
The above was generated from this physicseditor tool.
There's a problem when I try to add this to my 2d world. I'm using the javascript library matter-js and fromVertices() to generate the sprite.
This is what I see however.
It looks to me like each set of vertices has been positioned incorrectly with relation to each other.
Here's the javascript I'm using to add the "cannon".
var cannonBodyDef = {
position: Vector.create(300, 50),
density: this._cannon.density,
restitution: this._cannon.restitution,
friction: this._cannon.friction,
frictionStatic: this._cannon.frictionStatic,
frictionAir: 0.9, //this._cannon.frictionAir
};
var cannon = Bodies.fromVertices(300, 200, this._cannon.fixtures[0].vertices, cannonBodyDef);
World.add(engine.world, cannon);
It's also dropping to the floor (expected) then wobbling a little and falling straight through! Even though the floor is static: true. Not sure if that is related.

Json data for apexcharts

I have some problems rendering some data from a JSON in my apexchart series.
Here is the example of my chart with the data that I want to be in my JSON, and i don't know how to write it.
var _seed = 42;
Math.random = function() {
_seed = _seed * 16807 % 2147483647;
return (_seed - 1) / 2147483646;
};
var options = {
series: [{
name: "Q",
data: [0, 4800, 9500, null],
},
{
name: "Q - 1",
data: [0, 6500, 12000, 16000]
},{
name: "Q Target",
data: [15500, 15500, 15500, 15500]
},
],
chart: {
height: 350,
type: 'line',
zoom: {
enabled: false
}
},
dataLabels: {
enabled: false
},
stroke: {
curve: 'straight'
},
title: {
text: 'Clicks',
align: 'left'
},
grid: {
row: {
colors: ['#f3f3f3', 'transparent'], // takes an array which will be repeated on columns
opacity: 0.5
},
},
xaxis: {
categories: [' ', 'Month1', 'Month2', 'Month3'],
}
};
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();
#chart {
max-width: 450px;
margin: 35px auto;
}

If someone could give me a hint, is kindly appreciated.

The JSON looks like this , for retrieving data for the apexchart
{
"data_clicks":[
{
"name":"Q",
"data":[
{
"x":" ",
"y":0
},
{
"x":"Month1",

},
{

"y":null
}
]
},
{
"name":"Q - 1",
"data":[
{
"x":" ",
"y":0
},
{
"x":"Month1",
"y":1800
},
{
"x":"Month2",
"y":7150
},
{
"x":"Month3",
"y":10200
}
]
},
{
"name":"Q Target",
"data":[
{
"x":" ",
"y":11000
},
{

Highchart and timeline does not work with large dataset

I have been working on a large dataset : http://jsfiddle.net/470bddfp/1/
It's about 2600 entries
I don't want to group data, but use zoomtype feature instead
Unfortunately it does not work, I just change selection, and I have empty data.
What is even worst, is when I use smaller dataset like I made in this exemple http://jsfiddle.net/470bddfp/2/ zoomtype is working !
$(function() {
var chart = new Highcharts.Chart({
chart: {

"zoomType": "x",

}

Why my column chart is getting cropped in highcharts

I have implemented column chart using highchart .
My rightmost column is getting cropped and I am not able to get it fixed .
Please suggest which option is being missed by me .
{

EDIT
How can make grid lines to move out of axis on extremes and middle as marked in image

Correct way:
you just need to turn off clip in plotOptions
plotOptions:{
column: {
pointPlacement: "on",
clip: false,
}
}
Here is the Fiddle and also Thanks to Pawel Fus
Tricky way:
Here is what you want. i don't update my previous answer as that may help others.
but as the problem was charts cropped by highchart so i do the reverse and remove the integer number from clip-path= "url(#highcharts-NUMBER) attribute to have the full chart.
<g class="highcharts-series highcharts-tracker" visibility="visible" zIndex="3" transform="translate(51,100) scale(1 1)" style="" clip-path="url(#highcharts-1)">
Here the code to do this:
function showMagic(){
$(".highcharts-series-group").children()
.filter(function() {
var $this = $(this);
var lol = $this.attr("clip-path");
if (lol) {
$this.attr("clip-path","url(#highcharts)");
} else {
return false;
}
});
}
window.onload = showMagic;
Yes a little tricky, but it works! Here is the LIVE DEMO
UPDATE:
This part will be the answer to the update part of question:
we should format labels of xAxis :
"labels": {
"useHTML": true,
"formatter": function () {
if(this.value==0 || this.value==5)
{
return '<p style="margin-top: -20px;" >'+this.value + '<br> | </p> ' ;
}
else
{
return this.value;
}
}
},
Here is the LIVE DEMO

This is because of pointPlacement: "on". so just remove this part of yor code:
"column":{
"pointPlacement":"on",
},
When pointPlacement is "on", the point will not create any padding of the X axis In a column chart.
Here is the fiddle

First remove tickPositions, they are unnecessary when using categories. Then you need to set:
min: -0.5
max: categories.length - 0.5 (10.5 in your case)
startOnTick: false
endOnTick: false

highcharts tooltip not working properly for hacked gantt chart

The tooltips for my hacked gantt chart using highcharts doesnt seem to be working properly. I used the gantt chart provided by the highcharts team from here-:
http://jsfiddle.net/highcharts/r6emu/
I am using UnixTime and that seems to be somehow throwing off the tooltips. Here-:
http://jsfiddle.net/bootkick/NFS5M/
// Define tasks
var tasks = [{
"name": "a",
"intervals": [{
"from": 1366005607000,
"to": 1366006490000
}]
}, {
"name": "b",
"intervals": [{
"from": 1366059607000,
"to": 1366061858000
}, {
"from": 1366056006000,
"to": 1366058223000
}, {
"from": 1366047007000,
"to": 1366049299000
}, {
"from": 1366034407000,
"to": 1366036682000
}, {
"from": 1366030808000,
"to": 1366033050000
}, {
"from": 1366027208000,
"to": 1366029512000
}, {
"from": 1366018209000,
"to": 1366021296000
}]
}, {
"name": "c",
"intervals": [{
"from": 1366018209000,
"to": 1366019966000
}]
}, {
"name": "d",
"intervals": [{
"from": 1366005607000,
"to": 1366047612000
}, {
"from": 1366002007000,
"to": 1366002202000
}]
}];
// re-structure the tasks into line seriesvar series = [];
var series = [];
$.each(tasks.reverse(), function (i, task) {
var item = {
name: task.name,
data: []
};
$.each(task.intervals, function (j, interval) {
item.data.push({
x: interval.from,
y: i,
label: interval.label,
from: interval.from,
to: interval.to
}, {
x: interval.to,
y: i,
from: interval.from,
to: interval.to
});
// add a null value between intervals
if (task.intervals[j + 1]) {
item.data.push(
[(interval.to + task.intervals[j + 1].from) / 2, null]);
}
});
series.push(item);
});
// create the chart
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container'
},
title: {
text: 'Daily activities'
},
xAxis: {
type: 'datetime'
},
yAxis: {
tickInterval: 1,
labels: {
formatter: function () {
if (tasks[this.value]) {
return tasks[this.value].name;
}
}
},
startOnTick: false,
endOnTick: false,
title: {
text: 'Activity'
},
minPadding: 0.2,
maxPadding: 0.2
},
legend: {
enabled: false
},
tooltip: {
formatter: function () {
return '<b>' + tasks[this.y].name + '</b><br/>' + Highcharts.dateFormat('%H:%M', this.point.options.from) +
' - ' + Highcharts.dateFormat('%H:%M', this.point.options.to);
}
},
plotOptions: {
line: {
lineWidth: 9,
marker: {
enabled: false
},
dataLabels: {
enabled: true,
align: 'left',
formatter: function () {
return this.point.options && this.point.options.label;
}
}
}
},
series: series
});
I am relatively new to Javascript and Highcharts so pardon the obvious if any.

I figured it out. The problem was that the from,to timestamp pairs within a name/category are not in the ascending order. For the tooltip to work correctly, they need to be in the ascending order which is kinda weird.
