Xlabel does not appear in Figure

[Hakan]

 Hello,

I am newbie to Octave. There are some discussion about xlabel, but couldnt find any matching answer. Sorry if I repost same question somewhere in Forum.

I use XP and Octave 3.0.0. When I execute xlabel, ylabel or title (as per below), there is no change happening in Figure 1.0 (java based) window. Why? Where am I doing wrong? Thanks for your time and understanding.

x=linspace(-pi,pi,100);
y=sin(x);
plot(x,y);
xlabel('x value');
ylabel('sinx value');

It works for me. What is the version of your Java?

I can confirm this bug.

I'm not a newbie to Octave :-) but just now updated to Octave 3.0.1 from 2.9.15.

As hakantech wrote, but additionally also text() and legend() does not show characters in/on a figure.

I changed 'fontname' prop of a text object to "Sans" without improvement.

I enabled the java console, but it does not open on using jhandles.

Curiously, axis ticks have the numbers shown correctly (using a Courier type font?).

No error message visible. Is there some debug output available / can it be enabled?

* Octave 3.0.1, i686-pc-msdosmsvc
* WinXP SP2 DE (Germany)
* JRE 1.6.0_05

Switched to gnuplot for the time being ... but will try any sugestion you have.

regards
Ralf

I don't have many ideas for the time being, as it works OK for me.
What you can check is the properties of the text object and look
for something weird. You can also try to place a text object at
point (0,0,0) and set axis limits to [-1 1 -1 1 -1 1] (just to check the
text object is inside visible world for OpenGL).

Props look ok to me. You could look at the attachment:
textprop.zip
There, a simple test script and the saved text props with jhandles and gnuplot are included. Display with gnuplot is as expected. No text except axis tick numers with jhandles.

Gnuplot complains "missing Hevetica, using Sans". Well, it is XP. Changing fonts with jhandles to "Sans" or "Courier" did not help. What are valid font names for jhandles?
