carpet plots with matlab

if you are planning to plot some data as carpet plot, you can use matlab. there is a simple trick to do that.

in this example, i create a carpet plot for a 35040 vector.
first, i convert the data into a 365x96 matrix. then i plot it using the surf command, and change the view point with "view(0,90)"
that's all!
here the function:

---

function carpetplot(data,FigNr,colormap)



max_zeilen = 24*4;
zeile=1;
spalte=1;
i=1;
while spalte <= 365,
  while zeile <= max_zeilen,
      DATA(zeile,spalte)=data(i);
      zeile=zeile+1;
      i=i+1;
  end
  spalte=spalte+1;
  zeile=1;
end


x=[1:1:365];
y=[0:(1/(4)):24-1/(4)];

figure(FigNr)
clf
     axes1 = axes(...
           'FontSize',16,...
           'LineWidth',1,...
           'Box','on',...
           'Parent',figure(FigNr));%,...
%              'CLim',[-20000 -5000]);
     xlabel(axes1,'Tag im Jahr');
     ylabel(axes1,'Uhrzeit');
     grid(axes1,'off');
     hold(axes1,'all');




     set(gca,'XLim',([1 365]),'YLim',([0 (24-1/(4*60))]))%,'ZLim',([-20000 -5000]))

     surf(x,y,DATA,'EdgeColor','none',...
       'LineWidth',1,'Parent',axes1);
     view(0,90)



     colorbar1 = colorbar('peer',...
       axes1,'EastOutside',...
       'Box','on',...
       'FontSize',16,...
       'XLim',[-0.5 1.5], 'YLim', [-20000 -5000],...
       'CLim',[0 6]);


     %load('MyColormaps','mycmap')
     set(figure(FigNr),'Colormap',colormap)

    % set(axes1,'CLim', [0 4])
