checking with v8.2.0:

This behavior still exists in gnuplot.  Unable to recreate the problem with qt or fltk, where the subplots behave as expected while zooming, panning, etc.

As this report has been dormant for some time, only exists in gnuplot, and the developers has decided that the gnuplot toolkit will no longer be actively maintained (and now issue a warning on use to emphasize that fact), I'm marking this bug as won't fix and closing report.  If someone wants to dive into gnuplot and try to fix it, it can be reopened.

this bug is still valid with latest stable octave 4.4.1

Confirmed bug is still present with the development version of Octave and gnuplot 5. Does anyone interested in gnuplot care to work on this, or is it not possible or should be closed as a won't fix?

This applies to either panning, rotating, or zooming with the mouse.

Confirmed.  Octave is in the process of moving away from gnuplot so I'm not sure whether someone will get around to fixing this.

A possible workaround is to build from sources on the development branch of Octave.  The FLTK toolkit there has been much improved and I just verified that zooming of subplots works.

When trying to zoom into any subplot, all subplots disappear except the last-plotted subplot. This has been reproduced on several machines. Using 3.6.3 right now.

Is there some option that I'm missing for gnuplot?

FLTK plots appropriately zoom, but the quality of the plot is horrible (no subplot borders, etc.), so I prefer to use gnuplot if possible.

I did look into existing bugs and strangely do not find this. This makes subplots almost totally unusable.


x = -10:0.1:10;
subplot(2,1,1); plot(x, sin (x));
subplot(2,1,2); plot(x, cos (x));

Then just try doing any kind of zoom or replot, etc. The top plot will disappear.
