Turning on grid on ltiviewer

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.

After the ltiview() call,
grid on

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.

Hi guys,
I found a way but still not the best. The grid for Bode diagram is not displayed. Here's what I did;
obj = findobj('Type','axes'); for i = 1:length(obj) grid(obj(i)) end
Any workaround on this?
Thanks.

Got it. Need to add 'on' after grid. For bode diagram the command 'grid' is executed twice. Hence, it's turned off.
obj = findobj('Type','axes');
for i =1:length(obj)
grid(obj(i),'on')
end
