Fixed plot and variable-loop plot
显示 更早的评论
Hello everyone,
I need you help. I am trying to generate a plot with fixed lines (vertical ones) and on it, I would like to add a line that varies with the index k of a for loop that goes through a matrix. How can I avoid superimposition of all k-lines generated inside the for loop? I am trying to remove the "hold on" line but the issue is that Matlab removes the vertical lines too.
Thanks in advance for the help.
Here is the code:
assex=[0 25 25 30.7];
figure(1)
set(gcf, 'Position', get(0, 'Screensize'));
ylim([0 100]); yticks(0:2.50:100)
xticks(-1:1:35); xlim([-1 35])
xlabel('Spessore provino (cm)','FontSize',18)
ylabel('Umidità relativa aria (%)','FontSize',18)
set(gca,'FontSize',15)
grid on
xline(assex(1),'k',{'Superficie interna'});
xline(assex(2),'k',{'Freno a vapore - lato interno'},'LabelHorizontalAlignment','left');
xline(assex(3),'k',{'Freno a vapore - lato esterno'});
xline(assex(4),'k',{'Superficie esterna'});
hold on
for k=1:60:length(rh(:,1))
% scatter(assex(1,1),rh(k,1),'red','filled','SizeData',50)
% hold on
% scatter(assex(1,2),rh(k,2),'magenta','filled','SizeData',50)
% hold on
% scatter(assex(1,3),rh(k,3),'green','filled','SizeData',50)
% hold on
% scatter(assex(1,4),rh(k,4),'blue','filled','SizeData',50)
% hold on
% scatter(assex(1,:),rh(k,:),'filled','SizeData',50,'MarkerFaceColor',[0 0.4470 0.7410])
% hold on
plot(assex,rh(k,:),'LineStyle','-','Color',[0 0.4470 0.7410]);
title(string(strcat('Tempo= ',num2str(k/60,'%.2f'),' ore (',num2str(k/(60*24),'%.2f'),') giorni.')))
pause(0.0005)
end
NB: rh is a matrix with n x m dimension (index k goes along n).

One way would be to create the variable line once before the loop, and update its YData inside the loop.
% some random rh:
rh = 100*rand(1000,4);
assex=[0 25 25 30.7];
figure(1)
set(gcf, 'Position', get(0, 'Screensize'));
ylim([0 100]); yticks(0:2.50:100)
xticks(-1:1:35); xlim([-1 35])
xlabel('Spessore provino (cm)','FontSize',18)
ylabel('Umidità relativa aria (%)','FontSize',18)
set(gca,'FontSize',15)
grid on
xline(assex(1),'k',{'Superficie interna'});
xline(assex(2),'k',{'Freno a vapore - lato interno'},'LabelHorizontalAlignment','left');
xline(assex(3),'k',{'Freno a vapore - lato esterno'});
xline(assex(4),'k',{'Superficie esterna'});
% create the line once:
my_line = line('XData',assex,'LineStyle','-','Color',[0 0.4470 0.7410]);
for k=1:60:size(rh,1)
% set the line's YData each time:
set(my_line,'YData',rh(k,:))
title(string(strcat('Tempo= ',num2str(k/60,'%.2f'),' ore (',num2str(k/(60*24),'%.2f'),') giorni.')))
drawnow
end
