Hi everyone,

I displayed 2 systems using ltiview as shown below:

load ltiexamples ltiview({'step';'bode';'impulse';'nichols'},Gcl2,Gcl1)

I'm wondering how do we turn on the grid on these plots using MATLAB commands? (i.e without going to 'viewer preferences>style')

Thanks in advance guys.

%brute force way, it turns on the grids for all axes 
ha=findobj('type','axes')
arrayfun(@(x)set(x,'XGrid','on'),ha) 
arrayfun(@(x)set(x,'YGrid','on'),ha)

Hi,

Thanks for your reply.

However, the grid for Nichols plot doesn't look correct, as is, not the same as that displayed when I right click on the plot and select grid.

grid on only applies to the current axes

Ah, it appears ltiview opens a new figure and doesn't return the figure number either. If you findobj('type','figure') then you should be able to locate the figure number; from there you should be able to examine the properties of that figure to see if, for example, it has a particular Tag or Name, or if its children have distinctive properties.

Sorry, I do not have one of the applicable toolboxes so I cannot experiment with this.
