Canvas in timeline

[Matt Denman]

I've been playing with some canvas code I have inside of timeline, inside a div layer either under or over the events layer.  I'm working on something that needs to do drawings around groupings of events and to draw line paths from one event to others.  With the cool date to x/y coordinates provided by timeline, its actually fairly easy to have a canvas layer mixed in that will do this.

I'll probably do it for real as some time of "timeline plugin", so that timeline can get nice and trim and extensions like this are added as separate plugins.  A real deployment should bundle it all together anyway.

Is anyone else doing something like this or interest in doing something like this or even being involved when I get to it?

For what it is worth, I think it is an intriguing idea.  I have been toying with SVG and have had some of the same inklings of ideas for exhibit.  I certainly would be interested in hearing more about your ideas.... and I agree that the plug-in approach is the way to go for the kind of effort you are talking about...

One of the projects I am working on presents a series of events related to a court case.  The timeline is perfect to point of gaps in events or relationship between events.  I have some canvas code that lets you lasso draw around an area, which I would use to allow someone to draw around a group of events as a way to highlight that series.

Also, there is a view that shows a collection of financial transactions over time.  Some transactions are related to each other, but that can be hard to see in the timeline, even with colors.  Drawing lines between the related items is a way to show the flow of those related transactions as they happened in time relevant to other financial transactions.

Finally, when there is a gap in an expect event flow, like 1st and 15th (such as missing payments, etc.), then that gap should be highlighted in a way that is not the background colors supported already.
