Yes it does, but it was turned off while all the changes were made to minimize the flickering of the screen.

 I thing a good compromise is to plot the graph and then turn visibility off for the rest of the changes.

    hplt = plot (args{:});

    set (gcf,"visible","off");

    set (hplt(kk--), "markersize", 2);

or add the axes command before we turn it off

    axes;

    set (gcf,"visible","off");

    hplt = plot (args{:});

    set (hplt(kk--), "markersize", 2);

   

Both of these seem to get rlocus working again.

I think the consensus is to use the uiXXX functions for now.

I think that there is lots of work to get the sisotool fully working, and this might include improving the uiXXX functions.

So, in what do you think I must focus my project? because I still am not sure of how much I can get done during the summer. I am thinking the main part of the project would be the possibility to add controller poles and zeros and being able to drag them as well as the gain, should I spend some time before improfing the uiXXX functions too?

Please reply to all so the other octave maintainers can help us.

1)  Dragging the poles and zeros, on rlocus and bode plots, and then  redrawing each open window is top priority

2)  adding and deleting poles and zeros by using the mouse

3)  editing the plant or controller in a special window

being able to display 

 rlocus

 bode

 step

 impulse

? nichols plot

  nyquist plot

etc.
