#1904 splot with dot gives error

[Anonymous]

Bonjour,

I am using Version 5.0 patchlevel 5 last modified 2016-10-02, on a MacBook pro (OSX v 10.11.6)
Installion with MacPorts. This has been running fine for years (Thank you BTW).

I now have an error with the following test case:

---

set term wxt
set output

$d << EOD
1.0 2.0 3.0
4.0 5.0 6.0
7.0 8.0 9.0
EOD

splot $d u 1:2:3 w p pt 7 ps 1.0
pause -1 "Enter Return"

splot $d u 1:2:3 w d

---

The first "splot" works as usual (3 points). The second leads to this message (without any output):

     "dot_bug.gp", line 13: nextfrom_dynarray: dynarray wasn't initialized!

After a bit of google search I noticed some old messages, with similar (but not identical) problems. So I tried:

splot $d u 1:2:3 w p pt 0

It works smoothly.

This happens only with "splot". Everything is fine with "plot" (2D).

Any idea?

The error you describe ("dots" fails but "pt 0" works) was present in pre-release versions of gnuplot5, and in the qt terminal only for released version 5.0.0 (maybe also 5.0.1?). I cannot explain why you would be seeing it now. So I am guessing this is a different problem. It is especially puzzling because the error message you show comes from the hidden3d code, yet your test script does not include "set hidden3d".

I can't reproduce it here, but I'm not running OSX.

FWIW it also does not reproduce here on Windows using 5.0.5.

Everything was fine until last week.

1 - Adding "unset hidden3d" solves the problem. Thank you for the tip. I will use it until further progress.

2 - I'm not sure of it, but I think I remember there has been an update of MacPorts recently.
I will crosspost to them to check if it comes from there.

[Ethan Merritt]

Aha. So you were using hidden3d. Yes, I can reproduce the error message with dots in hidden3d mode. Still there in the current CVS version.

[Le Bourlot]

I did not know it! It is set by default, although I do not know where or why.

[Hans-Bernhard Broeker]

I do not know where or why.

You'll want to consult "help startup"

[Ethan Merritt]

Fixed now in CVS for 5.0 and 5.1

[Le Bourlot]

Thank you!

People at MacPorts (Mojca) applied your patch. After an "upgrade outdated", everything works as expected.
Thank you everybody.
