Sample Description
How to use this sample?
Hover any event marker to see custom HTML tooltip with event information. When data grouping level changes and several event markers are grouped in one - the information is shown in one tooltip. All event information comes from config.xml.
How it works
Besides the internal event marker tooltips, you can create HTML-based tooltips using mouse events and some special AnyStock functions.
In this sample HTML-based tooltips are created and two event marker events are handled: onEventMarkerMouseOver and onEventMarkerMouseOut - the first one triggers creation of custom HTML tooltip and the second one hides it.
HTML tooltip itself is just a simple div element, that is dynamically populated with data, that is obtained from eventMarker object, that comes from onEventMarkerMouseOver event.
Note, that if user hovers single event tooltip shows information from one event marker:
And if merged event marker is hovered - tooltips aggregates information from several event markers and shows date range in title and several rows with events info:
Another thing, that should be mentioned is the way custom tooltip is shown and hidden: take a closer look at showMarkerTooltip and hideTooltip functions to see that tooltips are placed with a small offset to avoid flickering on show and hidden with a small timeout for the same purpose.
You can read more about custom event marker tooltips at: HTML Tooltips for Event Markers article.
