handle to magnitude in bode plot - Sergio Dominguez - Mar 18 16:20:00 2004

Hi all, I'd like to draw/label/legend the magnitude part of a bode diagram plotted with the bode command. However, since the phase is drawn last, it is the current active graph, and hence, all my commands go to the phase. I have not been able (although I have searched!!) to activate the gain plot, does somebody know how to do it? Thanks! Sergio -- BOFH excuse #294: PCMCIA slave driver

I forgot to mention I am trying to do this from a script, clicking in the window or going to the menu's is not an option! Thanks again!

Hi Sergio, Why not use: [mag,phase,w] = bode(sys); Then you can subplot your results and add legends etc .

Re: handle to magnitude in bode plot - Sergio Dominguez - Mar 19 9:17:00 2004

Hi Jeff, Thanks for you answer. That is how I am doing it right now, but that means an extra overload in labelling which is automatically done with matlab's bode (freq (Hz), Mag (dB)... stuff). I did a little crappy function which plots the bode that way and labels and returns one handle to each subplot, but I lose much of the functionalities of matlab's bode and by adding all the extra stuff I felt like reinventing the wheel plotting matlab's bode and getting a handle from command line to the mag plot has to be possible, hasn't it? Thanks!
