kin_sector=[meteo.data.sector]';
figure(1)
fs=11;
set(gca,'FontSize', fs)
cc=jet(noy);
hold on
.........% I left the correct working part of the plot.
hold off
xlabel('wind direction')
ylabel('annual mean sectorial wind energy (MJ)')
title('1996 - 2022 Vlissingen')
axis([0.4 8.6 0 0.9])
set(gca,'xtick',1:1:8,'FontSize',fs)
set(gca,'XTickLabel',{'N','NE','E','SE','S','SW','W','NW'},'FontSize',fs)
box on
grid on 
orient portrait
print -dpng -r400 windclimate_allyears.png

this is the last part of my code from aan older version of matlab. after hold off the script seems to stop. Do I need a special command in my matlab version? Or do I have to put the code for the labels etc at an other place in the script?

this is the plot that is printed but no labels

kind regards Ellen

that seems not to be the solution. Probably the erro lies in de plot code

hold on
    for j=1:noy    % divide by 1e6 to get energy in MJ
      bar(1:nos,kin_sector(j,:)/1e6,'FaceColor','none','EdgeColor',cc(j,:),'LineWidth',1.5);
      %for k=1:15
         % sh=(k-8)*0.025;
      %plot(1+sh:nos+sh,kin_sector(j,:)/1e6,'s','Color',cc(j,:),'MarkerFaceColor',cc(j,:),'MarkerSize',2);
      %end
      plot(1:nos,mean(kin_sector,1)/1e6,'k s','MarkerFaceColor','k','MarkerSize',12);
    end
% highlight 1996 & 2015 & 2018
%     year=1;
%     plot([0.5:1:7.5], kin_sector(year,:)/1e6,'>','Color',cc(year,:),'MarkerFaceColor',cc(year,:),'MarkerSize',6)  % 
%     year=20;
%     plot([0.5:1:7.5], kin_sector(year,:)/1e6,'>','Color',cc(year,:),'MarkerFaceColor',cc(year,:),'MarkerSize',6)   % 
%      year=23;
%     plot([0.5:1:7.5], kin_sector(year,:)/1e6,'>','Color',cc(year,:),'MarkerFaceColor',cc(year,:),'MarkerSize',6)   % 
     year=1;
    plot(0.5:1:7.5, kin_sector(year,:)/1e6,'>','Color','k','MarkerFaceColor','k','MarkerSize',6)  % 
    year=2;
    plot(0.5:1:7.5, kin_sector(year,:)/1e6,'>','Color','k','MarkerFaceColor',[0.6 0.6 0.6],'MarkerSize',6)   % 
     year=3;
    plot(0.5:1:7.5, kin_sector(year,:)/1e6,'>','Color','k','MarkerFaceColor','w','MarkerSize',6)   %
     year=4;
    plot(0.5:1:7.5, kin_sector(year,:)/1e6,'>','Color','k','MarkerFaceColor','r','MarkerSize',6)   % 
    year=5;
    plot(0.5:1:7.5, kin_sector(year,:)/1e6,'>','Color','k','MarkerFaceColor','r','MarkerSize',6)   % 
hold off

print('-image','-dpng', 'windclimate_allyears.png')

Try using the OpenGL graphics rendering format as above. The version of Matlab you have probably used the vector format which can cause stray lines to appear and label issues in the plot

it looks like the problem is somewhere in this line

plot(1:nos,mean(kin_sector,1)/1e6,'k s','MarkerFaceColor','k','MarkerSize',12);

when I change the nr 1 in 2 or 3 I get another result.

kin_sector is a table with 27 columns and 8 rows.

each row contains the average windpower in one of the eight sectors. I guess mean(kin_sector,1)/ 1e6 should produce the mean of the column.

But problem 1 is not al rows al printed in the figure

is there an other posebility tot plot kin_sector (each row its own plot)? And should not there be be 27 times this row

year=1;
    plot(0.5:1:7.5, kin_sector(year,:)/1e6,'>','Color','k','MarkerFaceColor','k','MarkerSize',6)  % 

(one for every year? )

hold on
    for j=1:noy    % divide by 1e6 to get energy in MJ
      bar(1:nos, kin_sector(j,:)/1e6,'FaceColor','none','EdgeColor',cc(j,:),'LineWidth',1.5);
      %for k=1:15
         % sh=(k-8)*0.025;
     % plot(1+sh:nos+sh,kin_sector(j,:)/1e6,'s','Color',cc(j,:),'MarkerFaceColor',cc(j,:),'MarkerSize',2);
      %end
      plot(1:nos,mean(kin_sector,1)/1e6,'k s','MarkerFaceColor','k','MarkerSize',12);
    end
% highlight 1996 & 2015 & 2018
%     year=1;
%     plot([0.5:1:7.5], kin_sector(year,:)/1e6,'>','Color',cc(year,:),'MarkerFaceColor',cc(year,:),'MarkerSize',6)  % 
%     year=20;
%     plot([0.5:1:7.5], kin_sector(year,:)/1e6,'>','Color',cc(year,:),'MarkerFaceColor',cc(year,:),'MarkerSize',6)   % 
%      year=23;
%     plot([0.5:1:7.5], kin_sector(year,:)/1e6,'>','Color',cc(year,:),'MarkerFaceColor',cc(year,:),'MarkerSize',6)   % 
     year=1;
    plot(0.5:1:7.5, kin_sector(year,:)/1e6,'>','Color','k','MarkerFaceColor','k','MarkerSize',6)  % 
    year=2;
    plot(0.5:1:7.5, kin_sector(year,:)/1e6,'>','Color','k','MarkerFaceColor','k','MarkerSize',6)   % 
     year=3;
    plot(0.5:1:7.5, kin_sector(year,:)/1e6,'>','Color','k','MarkerFaceColor','w','MarkerSize',6)   %
     year=4;
    plot(0.5:1:7.5, kin_sector(year,:)/1e6,'>','Color','k','MarkerFaceColor','r','MarkerSize',6)   % 
    year=5;
    plot(0.5:1:7.5, kin_sector(year,:)/1e6,'>','Color','k','MarkerFaceColor','r','MarkerSize',6)   % 
hold off

% axis([0.4 8.6 0 0.9)])

Comment the axis line since this limits the y-axis values always to 0.9.

The bar plot produces values which are greater than 0.9.

Ellen 2023-12-3

You mean I have to give 0.9 another value for example the 600 wich is te highest Y value in the former diagram?

I ll try that.
