Splitting a combination of figures (also a philosophical question)

Splitting a combination of figures (also a philosophical question)

[Mojca Miklavec]

Hello,

This is not strictly a ConTeXt question.

I have two almost identical figures which I want to display one after
the other. Ideally that would be on the same page with the combination
of both having a single figure number (and possibly the two individual
figures having labels (a) and (b), but that's not strictly required).

However if the page breaks are not favourable, it would be OK to split
the two figures, so that one ends up on the bottom of the previous
page and the second one on the top of the new page.

I could use two separate figure numbers, but then I would need to
change the text that references the figures (and when the layout
changes, so that I would figure out that both figures would eventually
fit on a single page, I would have to change the text again).

Is there any reasonable (and acceptable) solution to that? One option
would be to have
    "Figure 1.5a: description"
on the first page and
    "Figure 1.5b: description"
on the second page while a reference to the figure would still show
"Figure 1.5", but I'm not sure if this is doable.

I would like to hear if anyone had a similar "challenge" and what
solution you used.

Mojca

What is the philosophical difference between Figure 1.5a ... Figure
1.5b and Figure 1.5 ... Figure 1.6?

Maybe (untested):
\startplacefigure [incrementnumber=no,number=no]
    \startcombination [1]
        {\externalfigure [firstoftwo]} {a}
    \stopcombination
\stopplacefigure
\startplacefigure [title=My combined figure title]
    \startcombination [1]
        {\externalfigure [secondoftwo]} {b}
    \stopcombination
\stopplacefigure

If your figures are almost identical, I would avoid this at all costs
- unless the figures would be on facing (recto and verso) pages. In my
view, it would be less confusing to have both figures on their own
page - assuming both can fit on a page. Make that page landscape if
necessary.

An alternate approach would be to have your figures in situ, but to
inset a small thumbnail-sized graphic showing the important part of
the other image (i.e. zoomed in), so that the reader can see what's
different.

Impressive.

I'm still scratching my head because I don't understand the magic
behind this trick (unless Hans and Wolfgang were reading my mind a
while ago when this was implemented), but curiously it does exactly
what I wanted to achieve.

To Alan:

The difference is that one then needs to say "See Figure 1.5 and 1.6"
somewhere in text instead of just "See Figure 1.5".
