I would like the tooltip to have a 'initial delay' - such that it acts more like a typical tooltip. I.e. the tooltip only shows after the mouse is stationary for a specified time, and then tracks data points instantly once shown.
Additionally, I would like the tooltip to be able to be replaced by a callback which provided the point values, such that they could be displayed elsewhere. So, for example, I might want to display the values of the currently tracked points in a div to the right of the graph, while still retaining the crosshair functionality.
Here’s a snippet that adds an optional delay to the initial tooltip display: http://jsfiddle.net/highcharts/xb4ax7v0/
Does this fix your problem?
@Pieter, IMHO the snippet at at http://jsfiddle.net/highcharts/xb4ax7v0/ is better, because it only adds a delay when first showing the tooltip, but when it has shown, it responds immediately to moving the mouse. That way is feels more responsive.
For now we are reluctant to add it to the core, as it isn't a very frequently requested feature and we have a strict policy of reducing bloat. And the snippet should work well.
Torstein, we now make use of this plugin: http://www.highcharts.com/plugin-registry/single/18/Tooltip%20delay%20before%20display
And the first feedback / comments are very good.
So possible to add this by default to HighStock?

I second the request. The concern about unresponsiveness would be addressed by allowing the display delay time to be configurable. As is, the tooltips are displayed too aggressively, appearing with the slightest passing of the mouse over the chart. This is not normal tooltip behavior, which is for the tooltip to appear only after a delay. With a proper delay the page behavior is less cluttered and the user less distracted.

@Torstein: I received this request also from our customers. Can this be an extra option on the tooltip api?

@Torstein: I would like the delay for the tooltip too. If someone wants "real time" tooltip, he could set the delay to 0 or null. Using version 2.1.9 I have a case when the chart line is under the legend. Because points of the line are under the legend, when I want to turn on/off series, the tooltip quickly shows up over the legend and legend is not clickable.
1. Personally I think this would appear as the chart were unresponsive.
2. Standalone tooltips can be implemented by using mouse events: http://jsfiddle.net/highcharts/Mw8WB/
