There are a lot of ways to handle data dynamically in Highcharts. You will use methods like Series.addPoint, Point.update etc. You'll find all those documented at http://api.highcharts.com.

The Highcharts SparkLine demo has only the static data. But I need to populate the chart with dynamic data by clicking a button. How can I achieve this behaviour? I read in the demo code something like $(element).highcharts('SparkLine'). Is it something related to dynamic rendering? If so, how can I use this?

@Anonymous: The link in the status posted to a simple demo. The http://www.highcharts.com/demo/sparkline sample shows a more relevant use case.

There are some features which makes sense only for sparkline charts and small sense for big ones. (Or just one example is not enough to show all is possible in sparkling charts)

Unfortunately it is wishful thinking that it just removed labels

Yes of course. The sparkline demo is just regular charts with labels removed.

Does the sparkline chart support scatter plots too?

Sparklines are just regular charts with all labels removed - I'll see if I can get a sample made as soon as possible, it's a pity that people think this is not supported by Highcharts. We should have a sparkline sample in our demo collection.

Hi Torstein - is this still under review? There are so many modern web apps using them now (and we want to keep up) it would be great not to have to use two charting libraries.

I've been playing around with that code example, and have gotten close to what I'm looking for. http://jsfiddle.net/dWgYS/73/
Anyone know how to get rid of the large spaces on either side of the sparkline? None of the margin options seem to work.

can be done easily enough: http://jsfiddle.net/DUfcR/1/
