Getting the tooltip values from Highchart graph in the source code

I want to get the Vacancies and Vacancy Rate values that appear in the tooltip when the cursor hovers over this graph, however ideally I want to grab it straight from the source code. I found a dictionary in the code, though its values are different to what appears in the tooltip.
Eg Value in dict: 34, Value in tooltip: 1
Eg Value in dict: 1055.6270096463, Value in tooltip: 15.8
I'm guessing the values are being changed by some function, though I can't find it in the code. Below is the section of code relating to the tooltip. Any help would be appreciated.
...
var xmin=$( window ).width()>1000 ? 1209564000000:1504188000000;

return 3.8*n*(1-n);

Highcharts - Can't change line colors

I'm looking to change the spider lines of the Highcharts spider web graph. I'm using a JSFiddle by someone else since mine isn't working for some reason.
I want to be able to change the line colors of the spider lines. What property do I change to get that?
$('#emotion-ranking-graph-bar').highcharts({
chart: {
polar: true,
type: 'line',
backgroundColor: 'rgba(255,255,255,0.0)'
},
exporting: {

},
title: {
text: '',
x: 0
},
pane: {

},
xAxis: {
categories: ['Joy', 'Sorrow', 'Anger', 'Seriousness',
'Information Technology', 'Administration'],
tickmarkPlacement: 'on',
lineWidth: 0,
labels: {

}
},
yAxis: {
gridLineInterpolation: 'polygon',
lineWidth: 0,
min: 0,
color: 'rgba(255,255,255,1)',
labels: {
enabled: false
}
},
tooltip: {

pointFormat: '<span style="color:{series.color}">{series.name}: <b>${point.y:,.0f}</b><br/>'
},

},

data: [43000, 19000, 60000, 35000, 17000, 10000],
pointPlacement: 'on',
color: 'rgba(0,0,0,0.7)'
}]
})

The lines going from the center to the outside are the yAxis, and the lines making the pentagon are the xAxis. You have to change the gridLineColor option on both:

Here you have a lot of options to fiddle: http://api.highcharts.com/highcharts/xAxis.gridLineColor

X-axis interval in Highcharts

I have this highchart graph displayed on my website. How can I set an interval for my x-axis? e.g. I want the fist value to be displayed and then skip the second and display the third.
Can this be done? Or do you always just HAVE to display all the data you're passing to the axis in an array?
My code: (timestamp is a JS array that contains my time. I can get that time in epoch format. act and temps are arrays for data to be plotted along y-axis)

You need to Add a tickInterval:2 to your x-axis decleration like so
xAxis: [{
categories: timestamp,
crosshair: true,
tickInterval: 2
}],

HighCharts axis flip on export

I have a Highchart in my web application. In the browser it displays normally which is as follows:
But when I export the chart it flips the axis and I end up with the following image:
Following are the options I am using for my Highchart.
var options = ({
chart: {
renderTo: 'chartDiv'
},
credits: {
enabled: false
},
title: {
text: ''
},
subtitle: {
text: ''
},
xAxis: {
type: 'datetime',
tickInterval: 7200 * 10000,
allowDecimals:false,
labels: {
format: '{value}',
rotation: 30,
align: 'left',
},
title: {
text: 'Date'
}
},
yAxis: [{
title: {
text: 'No. of rings'
},
min: 0
},
{ // Secondary yAxis
gridLineWidth: 0,
min: 0,
title: {
text: 'Accumulative Rings',
style: {
color: Highcharts.getOptions().colors[0]
}
},
labels: {
format: '{value} Ring',
style: {
color: Highcharts.getOptions().colors[0]
}
},
opposite: true,
}
],
tooltip: {
shared: true
},
legend: { backgroundColor: 'rgba(211,223,181,0.6)', layout: 'vertical', align: 'left', verticalAlign: 'top', floating: true, borderWidth: 0, x: 70 },
plotOptions: {
spline: {
marker: {
enabled: false
},
}
}
});
I have three series in my chart, the bar chart can have 0 values.
The data is coming from an ajax service, which I put in an array and then add to chart as follows:
chart.addSeries({
type: 'bar',
name: 'Rings per day ',
data: barData,
pointInterval: mainInterval
});
chart.addSeries({
type: 'spline',
name: 'Accumilative rings ',
data: spline1Data,
yAxis: 1,
});
chart.addSeries({
type: 'spline',
name: 'Planned Progress ',
data: spline2Data,
yAxis: 1,
color: "#FF0000"
});
What's wrong with my chart?

bar series is the key part. bar series forces chart to be rendered flipped. In your case use column. It displays differently on your browser because, most probably, you have an old version of Highcharts.

Connect limit's series in Highcharts

Updated :I'm trying to make a radar chart with hightcharts, but I can't connect this values(the ones which has asterisks for example):
$('#container').highcharts({
plotOptions: {
series: {
enableMouseTracking: false
}
},
chart: {
polar: true,
type: 'line'
},
title: {
text: 'Graph',
x: -80
},
pane: {
size: '80%'
},
xAxis: {
categories: ["Sponsor / Developer","Banks","SPV","Bank Legal DD","Services Legal contracts","Environmental license","Grid connection license","Construction License","Generation License","Site Studies\/License","Property\/terrain","Technical studies","EPC","Financial model"],
tickmarkPlacement: 'on',
lineWidth: 0
},
yAxis: {
gridLineInterpolation: 'polygon',
lineWidth: 0,
min: 0
},
tooltip: {
shared: true,
pointFormat: '<span style=\'color:{series.color}\'>{series.name}: <b>\${point.y:,.0f}</b><br/>'
},
legend: {
align: 'right',
verticalAlign: 'top',
y: 70,
layout: 'vertical'
},
series: [{"name":"Legal","data":[4,3,4,4,4,4,4,null,null,null,null,null,null,4],"color":"#206ef0"},{"name":"Licenses and Permits","data":[null,3,null,null,null,4,4,4,4,4,4,null,null,null],"color":"#f07820"},{"name":"Technical","data":[null,null,null,null,null,null,null,null,null,null,4,4,4,null],"color":"#ff0000"},{"name":"Financial","data":[null,null,null,null,null,null,null,null,null,null,null,null,null,null]}]});

The goal is to connect the series'limit of any series. I mean, if in excel I have the same series, financial model and Sponsor/Developer will be connected by a blue line. Look :
excel graph
How can I do it?
Thank you.

In the chart you can use scatter serie with enabled lineWidth. After last point, add reference to first point, then line will be printed.
{
"name": "Legal",
"data": [[0,4], [1,3], [2,4], [3,4], [4,4], [5,4], [6,4], null, null, null, null, null, null,[13,4],[0,4]],
"color": "#206ef0"
}
You can set line on the edge, by setting tickInterval / endOnTick / max options.
yAxis: {
max:4,
tickInterval:1,
endOnTick:true,
gridLineInterpolation: 'polygon',
lineWidth: 0,
min: 0
},
