JavaScript Echarts setup pie

I made pie chart, but I still have some setup issues.
I need to indent between segments, but I haven't found a suitable option, is it possible?
In the "Select" state, I want to save the scale of the selected element
When hovering, the segment increases to the outer radius, is it possible to make the increase go in both directions?
How it should look like:

Fill graph area with a gradient in HighChart

I'm using highcharts and react-highcharts to display some graph in my application. Ideally I would like to color the area of the graph with some gradient, from the documentation and this example the option that I should add is this:
plotOptions: {
area: {
fillColor: {
linearGradient: {
x1: 0,
y1: 0,
x2: 0,
y2: 1
},
stops: [
[0, Highcharts.getOptions().colors[0]],
[1, Highcharts.color(Highcharts.getOptions().colors[0]).setOpacity(0).get('rgba')]
]
}
}
},
I'm trying to replicate the same with the configuration of my graph but it doesn't work, the graph looks exactly the same as if there was no fillColor option added. Here's the config of my graph:

If I remove the plotOptions.area property nothing changes in the graph, what am I missing?

Notice that with your current data the error occurs in the console:
https://assets.highcharts.com/errors/15/
The fillColor feature works only for particular series - like area, pie, funnel, pyramid, arearange etc, so you need to define the type of the series that you want to implemnent.

Calculating percentage value for each serie in highcharts

I am trying to calculate % values for each series, what I managed to find is function like
formatter:function() {
var pcnt = (this.y / dataSum) * 100;
return Highcharts.numberFormat(pcnt) + '%';
}
But what confuses me is how can I make dynamically this function so it can be applied on every serie object that is provided
Emphasize on dataSum from function above.
I tried googling just in case highcharts provide already some solution that they have in their documentation but sadly I did not find anything, only thing I found is to concatenate already provided value with + '%', and that is far beyond real value of percentage of that specific serie

var chart = new Highcharts.Chart(

Has anyone ever step onto solution that provides % values of series by any case ?
I am trying to calculate % of total_children, and % of num_cars_owned serie as they are separated objects of serie array.
You can find code example on link HERE http://jsfiddle.net/JeLrb/538/

You need to calculate dataSum value:
tooltip: {
...,
formatter: function() {
var dataSum = 0,
pcnt;
this.series.points.forEach(function(point) {
dataSum += point.y;
});
pcnt = (this.y / dataSum) * 100;
return Highcharts.numberFormat(pcnt) + '%';
}
}

How to display no data found in highcharts

In highcharts, if there is no data found in the json value, I want to display an error message.
I used this code:
if(options.series[0].data.length == 0) {
alert('nodatafound');
} else {
var chart = new Highcharts.Chart(options);
}
This error appears:
TypeError: options.series[0].data is undefined
Data from JSON:
{

You can use no-data module which allows do that.
