This works for me with the development code.  It probably got fixed somewhere in the last year, or an upgrade to the FLTK libraries did it.  Closing report.

Confirmed.  It's an annoyance, and probably difficult to actually track down and fix.

Here are some workarounds:

1) Use 'refresh' on the command line following the plot command.

2) Change the comma-separated line 'figure, plot (x,x)' in to two separate commands separated by a newline rather than a comma

figure
plot (x,x)

3) Put the command in an m-file and run the m-file.

Contents of tstmfile.m

x = linspace (0,1);
figure, plot (x,x)

4) Switch to a different toolkit such as gnuplot rather than FLTK.

5) Start with 'octave --no-gui'.  This has a CLI interface, but the default toolkit is qt rather than FLTK.

Dear all,

if I run octave-cli and type

x=linspace(0,1);
plot(x,x);

the plot appears immediately, but if I then type

figure,plot(x,x);

I get an empty and transparent window (see attachment) and I have to double click on it to see the content. No problem with

plot(x,x),figure,plot(x,x)

This happens since I installe 4.0.0 PPA (trusty).
