My opinion on clearing axis labels; is that upon an update the labels should be
cleared out. I am using Timeplot to visualize data from Biofeedback. In the
case of a plot of "live" data scales of the plot can change. I have noticed
that when doing the live update the labels on the axies persist even when
scaling changes, so you will see cluttering and sometimes i see lower values,
on vertical axies, above higher values, when the plot data has changed enough.
Generating plots that don't change, this really is not an issue.
I got the showValues toggle to work. I was being a bit too aggressive clearing
labels from plot, i cleared the flag poles!
I am still working on ironing out the time axis label clutter. I think a
solution would boil down to using smaller jumps in time concepts in attempt to
cut down on clutter. for instance; displaying the time axis based on seconds
would give ~60 labels before it would switch to using minute labels. I have
gotten good results simply adding a concept of "FIVESECONDS" that would fit
between "SECOND" and "MINUTE". The data to be looked at, in this application's
case, would never really exceed 9 or 10 hours per plot, so i have not
experimented any larger than that, but i think the concept would still apply.

Hmm, that's a good point. I didn't think of the case of multiple plots
on the same page. I'll revert it to the firstChild.

I honestly don't remember :-)
What is you opinion on that?
