Re: Trying to make a respectable looking Hist3 plot and having big difficulty

Hi Nicholas  - Thanks Guys - consider closed please

That's great - I didn't think of the packages version (I'm very new to Otave) and when I check I had 1.2.3 like ?Doug?, he upgraded to 1.3.0 and his became like good like yors - so makes total sense it is that
I tried to upgrade to statistics-1.3.0  but then it told me it wanted dependency Octave 4.0.0 and the presentation I needed it for was 3pm so I couldn't risk a new version so close to deadline

But that explains everything so I'm very confident will fix mine too.

Guys - so I'm very new to Octave at all - these 3 different Graphics packages I didn't really grasp,  .... Do they all use different commands or is the interface completely standardised?
I know I've sometimes accidentally been reading GnuPlot documentation and found the commands dont quite work in Octave so I'm guessing Octave has a standard interface it converts into Gnu Plot or something
Is it easy to interact directly with GnuPlot ? I'm guessing it is probably more advanced than Octave for plotting, and that it's target is professonal science publications

Thanks very much.

Tim

Ah so you got same as me? Thats interesing.
I should add I'm using a Windows install - this may haev a lot to do with it...

I'm actually not intelligent enough (yet) to understand how to switch between graphics packages, or how to use them - I'm just using default Octave.

I'm using Octave 4.2.1 and statistics 1.3.0 as well. Similar to the above, output looks fine on all three graphics toolkits, gnuplot being a bit less 'clean' than the others, comparison image attached.

Octave (at least on windows) is built with 3 available graphics toolkits: qt (default), gnuplot, and fltk.  you check them and switch between them using the 'graphics_toolkit' command.  So, I produced the attached output with the following:

   10   10
   10   10];
