This is coming along really well I think. That abstract about adjusting
time scale is interesting, although might be overkill for what we need here.
- Alignment of added and deleted
- Why are the added and deleted bars always shifted from each other? if
each horizontal instance is an "edit" wouldn't they be aligned?
- Thickness of bars
- Have you explored much thinner bars? 1px could even work i think.
- Temporal scaling
- I feel pretty strongly that we should include the gaps for time
that edits are not happening, e.g. if by default each day was 1px, if
"zoomed" that scale could change to hourly, etc.
- User changes
- For consecutive edits for the same user you could use the same
vibrancy of blue, for the initial edit, and a significantly lighter, or
more transparent for subsequent edits by the same user.
- Vertical scaling
- For the given view bounds you could scale the vertical height so
that it stays within the bounds of the control.
- Secondary graph?
- I don't quite understand what the secondary single color graph
below the main one is?
- Its possible to select parts of the graph, but unclear what
selecting it does, or if it has any purpose.
- Would you use selection as a means of "zooming in" to
see different time scales, if not what is your plan for this. When/if
zoomed in, how will you show your relative position in the whole

On moving the slider to the left corner more data gets progressively
added. Additions are blue bars in the positive direction and deletions are
red bars downwards.I'm using a power scale to scale down the edit sizes (
The size of the bar is proportional to the edit size). It works much like
the google finance chart slider.
In the prototype above the selected portion is show below with in the same
proportions (It will be enlarged , have a tooltip on hover showing the
details related to the edit etc & have a handle to select the edit to begin
the animation from).
I tried showing the temporal distance between the edits by coloring the
bars based on the time difference between consecutive edits (The data that
you see in the slider is the edits from the page JSON). This isn't working,
in the prototype a user can hardly make out the time difference between the
edits. Another approach to show the time difference between two edits that
I came across was showing the time difference between each edits with a
I'll be adding the basic slider to the viz tool in the coming week.
Looking forward to ideas and comments.
I'm a complete newbie to design, I haven't yet gotten around to read Tufte
:-). I've been looking at a lot of vizualisation by Ben Fry & Mike Bostock.
I've attached a screen shot of the prototype.
