Can I change the Simulink default settings in bode plots like frequency unit in Hz instead rad/s and define a fix frequency range in "Model Linearizer"?

Hello,

I would like to change the default settings described in the title, because I need to create different Bode plots with the same settings in Hz and a fixed frequency range.

At the moment I have to reset these settings in each study.

Thanks for the answer

Hi Rai,

• You can change the unit of frequency in the plots using the 'Toolbox Preferences Editor'.

https://www.mathworks.com/help/ident/ug/toolbox-preferences-editor.html

"The Toolbox Preferences editor allows you to set plot preferences that will persist from session to session."

• For setting a fixed frequency range for multiple plots, you can download all the plots as MATLAB figures (.FIG) and then run the below script to set the frequency range.

%List of all figures
fig_list = ["fig1.fig", "fig2.fig", "fig3.fig"];

for i = 1:numel(fig_list)
    curr_fig = fig_list(i); %Open a figure
    q = open(curr_fig);
    ax = q.CurrentAxes;
    ax.XLim = [3 8]; %Set the desired range
    %saveas(gcf,curr_fig); % Overwrite the figure
    close %Close the figure
end

Hope this helps!
