Animations; Blinking in octave 3.23; Worked well in 3.03; platform Mac; suspected all platforms

[Ladislav Kocbach-2]

Problem: Animations; Blinking in octave 3.23 not 3.03: platform Mac; suspected all platforms
This problem never occured before, since Octave 2.1

Taking code from "help refreshdata" 
          x = 0:0.1:10;
          y = sin (x);
          plot (x, y, "ydatasource", "y");
          for i = 1 : 100
            pause(0.1)
            y = sin (x + 0.1 * i);
            refreshdata();
          endfor
This code performs horrible animation, since all the graphics is redrawn, with blinking
There is nothing like 'erasemode','xor' or similar, the display blinks and is uncomfortable

This was not a problem with older versions of octave
For example,
the equivalent code which works smoothly in octave 3.0.3.
( and another equivalent code in octave 2.99 also works smoothly)
          x = 0:0.1:10;
          y = sin (x);
          PPL=plot (x, y);hold on;
          for i = 1 : 100
            pause(0.1)
            y = sin (x + 0.1 * i);
            set(PPL,'ydata',y)
          endfor
also misbehaves in octave 3.2.3.

The suggested reason:
somebody has been improving the communication with gnuplot and improved it too much
(unnecessary "clean figure" inserted probably)

My suspicion is that the same problem accurs also for other platforms.

Thank you!

Hello

For Octave 3.2.3/MinGW for windows and octave 3.2.3 on cygwin,

>           x = 0:0.1:10;
>           y = sin (x);
>           plot (x, y, "ydatasource", "y");
>           for i = 1 : 100
>             pause(0.1)
>             y = sin (x + 0.1 * i);
>             refreshdata();
>           endfor

worked without blinking.

This problem was discussed before 3.2.3 release. Please see,

http://www.nabble.com/changeset-9395-(3.2.%EF%BD%98-branch)-should-be-applied-not-only-x11-term-but-on-windows,-wxt,-(-and-aqua)-term-td25326547.html

Which terminal are you using ? Aqua term or X11 term ?

I do not have Mac so that I cannot confirm the blinking at least on windows ( MinGW / Cygwin)

Please wait Mac users' replies.

Regards

Tatsuro
