highcharts - is it possible to zoom pie charts - charts

Question

I'm wondering if it is possible to zoom in on a slice in a pie chart.
My chart is modeled after this example jsfiddle example
chart: {
renderTo: 'container',
type: 'area',
zoomType: 'x',
}
But it doesn't seem to work with pie charts. Am I missing something here?
Ideally, I would have a pie chart with 2 layers, where the outer layer serves as a child of the inner layer. When selecting a child slice, I could then have an entire pie chart showing that slice alone, along with its own children, etc.

Answer 1

Unfortunaltely zoom is not allowed for Pie Charts as its properties show you
x: to zoom in x-axis
y: to zoom in y-axis
xy: to zoom in both axes
but you can use size property with JavaScript to show zooming.

Answer 2

I think I found what I was actually looking for. It isn't zoom, but rather the option of capturing click events on slices.
In order to do that, one must use the allowPointSelect attribute, which can be added to a pie chart like this (just one of several different ways):
plotOptions: {
pie: {
shadow: false,
allowPointSelect: true,
},
}
Then in order to capture clicks one has to declare the events attribute in the series being used:
series: [{
name: 'Example',
data: [
{
name: 'Firefox',
value: 45.0
},
{
name: 'IE',
value: 26.8
},
{
name: 'Chrome',
value: 12.8,
},
],
size: '100%',
point: {
events: {
click: function() {
// some code to execute when clicking a slice
alert('Slice name: ' + this.name + ' and value: ' + this.value);
}
}
}
}]
Then in that click function, any javascript code can be executed, and the declared fields in the data can also be accessed. So a second pie chart could theoretically be created on the fly.
