Size of figures makes them move to the end... but when?

Post by Stef Pillaert »

Hello,
I have a lot of figures (in floats, "Here if possible"), and I notice that when they are "too big", they get moved to the end of the section (pushing all the floats that come after it also to the end, of course). But: all my figures are scaled to a max. % of textwidth en max. % of texthight, keeping the aspect ratio: how can they be "too big" then? Whenever this happens, I try to scale down the figure causing the problem, untill this doens't happen anymore.
Is there a way to know "in advance" when the figures will be too big? Is there a maximum percentage, or a maximum absolute size, or ...
Now I feel like "try-and-error"-wise changing the percentages untill it doesn't get swapped to the end, without "knowing" what's/why this is happening. But this is probably because I 'm just using LyX as a LaTeX dummy :?

Hi Stef!

It would be good to see the effect with the actual code. Can you please post a small LyX example document in the same way you did with your original document, that shows the problem. Please also as a pdfLaTeX export (so I can test without LyX) and with a sample figure file. We can add attachments to forum posts, there's a link below the text edit field for this.

OK, by narrowing it down to a small example, I noticed that it seems to be caused by rotating the figures within LyX: there is an option "first scale, then rotate" (sorry, translation from dutch LyX-version). Sorry that I didn't narrow it down to the rotation of 90° from the start...
    When I don't use this option (which seems logical to me), I get the problem (see files "test_with_problem").
      When I do use the option (didn't try this before, sorry), the figure is in the correct place in the pdf, but... it is too small (which is expexted, if you scale first, and then rotate it....). So by using the option, my problem dissapears ... but the figure is too small :)
      (I'll add the actual figures in a reply next: it seems that there is a limit to the attachments...)
      [Update: sorry, the first version of the test.lyx file could be the wrong one, now it should be OK]

      hmm... and now I'm wondering if it is really the rotation that's causing the problem: here is another situation with (I think?) a problem similar to the previous one:
      why are the figures starting from "figuur 2" (= "011.pdf") pushed so far to the back? (In the original document, which is longer than this example, it was even a lot further to the back, at the end of the entire section)
      "Figuur 2" has (in LyX) a scaling of max. 90% of textheight and/or textwidth, and keeping (of course) the aspect ratio. I understand the output places this page on an entire page, but why so far from it's location in the LyX-text?
      Or am I really missing something about how LaTeX arranges figures (in floats)? Maybe LaTeX can't solve my problem without making the rest of the text more "ugly" (e.g. with bigger spacings between the formulas)?

      (Is it ok if I only add the first two figures? Let me know if someone wants all the figures separately)

      I'm not sure. I don't have any experience with figure rotation. Instead of "Here if possible" did you try "Here definitely" ?

      If I use 'here definitely', then the figure is exactly where I ask ... but the rest of the lay out is not OK (way too much spacing between formulas, ...). I don't want to insist on the exact place, most of the time LaTeX does a good job on placing the figures.
      But I don't understand why the figures in my examples are placed completely to the end of the section, while they are not bigger than 90% of text heigth and width ....
      I doesn't seem logical to me: it seems that they could have been placed earlier in the text ...

      Remove all instructions for placement for the figures. Every decision you make, is restricting LaTeX.
      If you decide you want the picture here, LaTeX cannot place it at the bottom of a page or on a page of its own. The float is passing page by page without a suitable place, so all images are ooutput at the very end.
      The smart way: Calm down and take a deep breath, read posts and provided links attentively, try to understand and ask if necessary.

      OK, removing all the settings indeed made it a lot better, thanks!
