Subject: Re: [Engine-devel] [UX] how to design a bar/line chart?
Hello all,
We use to have a good solution in the period pre-WPF.
A line chart (used to be in flash) that works like a plotter:
The Line Bar (not bar) had a small animation that shifted all the bar to the
left.
When a new data arrived it just added a new line (to the right) and as I said
before, in parallel it always shifted slowly to the left.
Any chance you still have some screenshot or mockup so I can imagine it better?
The animation gives the impression that data is streaming and when a
real new
data arrives the user gets it very fast.
We have to sync between the animation and the rate of the arrival of the data
but this is easy.
If we can't find a good framework it can be created from scratch with JS, svg
or canvas.
We need to be careful about what we will use. oVirt is supposed to work on FF 17 [1]
but the HTML5 canvas works only since FF23 [2].
@Einav:
Is there a chance that we could start support only FF23+ and IE9+ (this one is already
OK)
because of this feature?
Now regarding its position:
Rollover is good but not enough, we should somehow put it in the lower panel
under general or even another tab - (live data).
This is a bit different requirement. The point of this specific is to give a better
overview in the main tab. If it will be done we can decide if we want to give more
details in sub tabs.
We could later on have a (live data Tab) in other places as well like
host,
cluster...

AFAIK - oVirt is handling it ('it' == having no internet connection) well.
