I have a graph that has some very short-duration events, between 1/60000 and 1/600 of the entire timeline. Currently, I cannot select and drag a small enough range for these events (changes in edge weights) to show in the animation. A solution that would work well enough for me is to be able to select (and drag) a point-in-time on the timeline rather than a range. Perhaps this is possible right now and I am missing it, but if not it would it might be a very helpful intermediate feature on the way to automated animation of a dynamic graph.

Is the timeline player still on the radar?

Thank you jbilcke for the summary which helps us in having an overivew about the different suggestion for implementing timeline player.
I like the precise date approach and i think it is the most appropriate way. I am interesting in working in such a component so, can I have an idea about what has been done so fare in timeline implemntation and what are the remaining tasks.
In addition to that can I have a brief about the idea of implementing the timeline and the files that i need to works on.
Thank you and looking forward to recieve a reply ASAP Pleeeeeeeease

Let's continue the discussion. I personally agree with your statements. I think setting a precise date to the timeline is the most urgent need. Others need more discussions anyway.

The first message of this thread (mine) will be updated if necessary, in order to reflect the progress of the discussion.
Timeline Player
A timeline player : you press a "play" button, and the graph will animate to show changes in your dynamic data.
Potential benefits:
- easier to visualize dynamic data
- added-value compared to similar softwares ? (seems a lot of people want it)
- very useful for show cases / movies
Potential issues:
- how fast should we see data ? which speed choose by default ? how would you like to change it ?
- what should be animated ? the lower interval ? the upper ? both ? how could we change this, while keeping it simple ? three button ? another way ?
- how to keep it easy to learn and use, without cluttering the interface ?
Suggested solutions, mockups or usecases:
- dual mode (basic / advanced) ?
- I was going to implement it like this: You click on one of the three time markers (begin,end,both), which turn red. Then you hit play, and this will move the selected marker.
Current status: planned at first, development halted (some code been produced), discussion opened to the community.
Zoomable Viewframe
To be able to zoom within the timeline viewframe.
Potential benefits:
- ability to navigate through large datasets, yet precisely
Potential issues:
- how to keep it as simple as possible ? simple vs advanced mode?
- how not to "get lost" if you zoom too much? how to keep the "global view" (ie. to be able to know where you are in the global timeframe) ?
- How do it, precisely : two views (one "zoom", one "global" ?) ? one atop the other ? what kind of visual signal, markers, feedbacks should we use ?
Suggested solutions, mockups or usecases:
- inspiration from audio editing programs
- use of the mouse wheel ?
Current status: Planned at first, prototyped. Seems a bit hard to do it correctly (ie. easy and useful), discussion opened
Precise Timeline
To be able to enter a precise begin-end date for the selection
Potential benefits:
- precise selection
Potential issues:
- not really, except to do it nicely
- with or without a calendar picker ?
Suggested solutions, mockups or usecases:
- I suggest the following: Show the begin date, and the End date of the selection.
If you click, or double click on it, you can change the value (or select it from a calendar?)
If you move the mouse on it, you get a "classic" visual feedback to show that you can edit it.
Current status: ?
Since development of Gephi is now mostly community driven, I believe this is essential to let everybody participate, and propose solutions (eg. screenshots from audio software, photo mockups, drawing..). For my concern, I am neither an ergonomist or a designer, and I can only suggest, transform, remix things I saw in other applications
the zoomable timeframe seems particularly tricky to me. Like Snurb, I did use audio editing software, but I might be biased since I already adapted myself to them, to the point they seems normal to me (maybe these old audio editing software could be improved too!), but might not to beginners or non-technicians.
Moreover, they have the advantage that they can show something : notes, partitions, waveform, while the current timeline is blank, thus one get an immediate feeling on the effects of the modification/zoom.
Maybe this could be the topic for another improvement (show some statictical data within the timeline ?)
