Coloring Different Models in Model Array Plots (Matlab) -


i visualize different responses of different systems in single plot matlab's control toolbox, , colorize various curves easy differentiate between different systems.

the response plots created using control toolbox - e.g. step response (using step), response arbitrary input (using lsim), etc.

when using separate model objects different systems, it's easy create multi-color plots, e.g., step response: step(sys1, 'b', sys2, 'r') give 1 blue curve , 1 red cure, if sys1 , sys2 both single system model.

however, if plotting model array, there's no way differentiate between various curves belong same array. e.g.: step(sysarray, 'b') make curves blue. step(sys,'b','r') invalid - no easy way specify various colors. also, using "edit plot" tool, selecting 1 curve selects curves, , changes properties (e.g. line color) affect curves.

is there way control properties of each curve separately?

there's no built-in function this, have roll own functionality

% create n-by-3 array of colours use coloursarray = rand(numel(stackedsystems),3); % example put in random colours % plot step(stackedsystems); title('my custom title'); grid on % change colours ha = findobj(gcf,'type','axes','visible','on'); % handles of axes (for mimo responses) jdx = 1:numel(ha)    hl = findobj(ha(jdx),'type','line','visible','on'); % handles lines    idx = 1:numel(hl)        set(hl(idx),'color',coloursarray(idx,:));  %  change colour    end end

i work spip , plugin called tagsphere works fine tags in spip. have tag groupe put 1 article tag. when click on tag in tagsphere send me before menu can see articles linked tag. want send me directly article without see tag menu before. here code model of thagsphere: <div id="tagsphere-#env{id_article}"> <ul> <boucle_mot(mots){id_groupe ?}> <li>[<a href="#url_mot">(#titre)</a>]</li> </boucle_mot> </ul> </div> anybody idea? if want skip tag page, have link directly article. <b_article> block prevents display tag if no article linked. <div id="tagsphere-#env{id_article}"> <ul> <boucle_mot(mots){id_groupe ?}> <b_article> <li> <a<boucle_article(articles){...

ruby on rails - In a controller spec, how to find a specific tag in the generated view? -

i know integration tests preferred need ran in controller test, i'm testing gem injecting html code in view, xhr can't run in feature spec (if can, please explain me how :) ) so rspec controller tests can assert selector present (with capybara) : response.body.should have_selector('#foobar') has_selector? call all method capybara find selector. what want last child of body , assert id in particular. afaik it's not possible have_selector. what : all('body:first-child').first.id.should == '#foobar' however, capybara dsl, defined (more or less): def all(*args) page.all(*args) end and page empty unless use visit it's integrations specs. how can use capybara all method inside rspec controller test ? i can't test right after googling seems trick def page capybara::node::simple.new(response.body) end source
