Thank you, that appears to produce the effect I'm looking for.

@Jason, it is settable from the outside, see http://api.highcharts.com/highcharts#drilldown.activeAxisLabelStyle

Nevermind. I found that the dark blue color #0d233a is actually hard coded into drilldown.js. Making that adjustable is my suggestion.

If you look at your example: http://www.highcharts.com/demo/column-drilldown/gray

and look at the darker colored themes, notice how the column title on the x-axis and the value on the bar (before any drill down) is set to a dark blue color that is difficult or impossible to read. After drilling down, the colors change the the gray they are set to. After much effort, I cannot figure out how to change that dark blue text color. None of the normal ways seems to have any effect.

For example, in the following, I can rotate the data values, which which suggest that I would be able to change the color from the same place, but I cannot. It always remains the dark blue.

plotOptions: {
series: {
borderWidth: 0,
dataLabels: {
enabled: false, // Show column values in-graph
rotation: -90,
color: '#999',
align: 'left',
style:
{
fontSize: '10px',
fontFamily: 'Ariel, Helvetica',
fontColor: 'white',
},
}
},

Hi, I am new to this place. Can we do something like this - http://www.adobe.com/devnet-apps/flex/tourdeflex/web/ (Other Components -> Chart Extensions -> Chart Drilldown Animations) for both Bar and Pie charts

You probably want to use the point.click event. See http://highcharts.com/ref/#plotOptions-pie-events--click.

Also, you have point seletion modes. Check out http://highcharts.com/ref/#plotOptions-pie--allowPointSelect and the associated events, http://highcharts.com/ref/#plotOptions-pie-point-events--select and http://highcharts.com/ref/#plotOptions-pie-point-events--unselect

I have got the click event to work, but that only works when clicking the background. I am doing rendering pie charts, and I'm unable to use the "selection" event. How do I do a drill down on a pie chart? The documentation states the "selection" event only works when specifying the zoomType (x for example). But that does not apply on a pie chart. Can anyone help? It seems strange that it is so difficult to do a drill down. Side note: I also think it's strange that the "click" event only works on the background. There should be a click event that if captured whenever they click anywhere on the canvas.

It appears to me that there needs to be an event listener called "dblclick" that allows for double clicking a specific chart area. The current "click" listener is restricted to only the plot background - which serves no purpose. While the "selector" listener requires a user to drag over a chart area - not very user friendly.

I see what it's doing. The callback method is fired when clicking the label, not that actual pie segment. is there a way to do a drill down on the pie segments itself?

Ok, I think I see how it works. But I'm having problems implementing it. I have this within my chart: {}
events: { click: callBackMethod }
But the callBackMethod() does not get fired when clicking the section of the pie. Any ideas?

See http://highcharts.com/studies/drilldown.htm for a live demonstration

Can you provide a simple example of how to use a callback to simulate a drill down?

This can be accomplished by adding callbacks on click events.
