Hi,

i have this code an want to save the figure as png and fig , if there are 5 subplots.

The name should be then for example: hours_5, hours_10....

for i=1:100
    if rem(i-1, 5) == 0
              figure;
    end
    
sgtitle('WSPL zeitlicher Verlauf Modell D Teil 2')
a(i)=subplot(5, 1, rem(i-1, 5)+1)
hold on;
[maxHQextrem,indexHQextrem]=max(Hoehe_HQextrem(:,i)- Hoehe_Z(:,i));
[maxHQ5000,indexHQ5000]=max(Hoehe_HQ5000(:,i)- Hoehe_Z(:,i));
[maxHQ10000,indexHQ10000]=max(Hoehe_HQ10000(:,i)- Hoehe_Z(:,i));
str = ['Maximaler Überlauf [m]: HQextrem ',num2str(maxHQextrem),' HQ5000 ',num2str(maxHQ5000),' HQ10000 ',num2str(maxHQ10000)];
b(i) = annotation('textbox','String',str,'Position',a(i).Position,'Vert','bottom','FitBoxToText','on');
hold on 
% annotation('textbox', 'String',str)
p1=plot (Distanz_Z(:,i) , [Hoehe_Z(:,i), Hoehe_HQextrem(:,i), Hoehe_HQ5000(:,i), Hoehe_HQ10000(:,i)]);
title(['Zeit [h] ', num2str(i)])
grid on 
xline(indexHQextrem,'-','Maximum','LabelOrientation','horizontal')
xline(indexHQ5000)
xline(indexHQ10000)
leg=legend(p1,{'Geländehöhe','HQextrem','HQ5000', 'HQ10000'})
title(leg,'WSPL')
newcolors = {'#000000','#7E2F8E','#0000FF','#00FFFF'};
colororder(newcolors)
xlabel('FKM [km]');
ylabel('Höhe über NN [m]')
xticks([738.98 1734.44 2744.03 3687.56 4722.17 5762.52 6831.7 7228.84])
xticklabels({'118','117','116','115', '114', '113', '112', '111'})
end

thanks in advance

use the print function or exportgraphics to control the resolution of the image

To maximize, you can use the 'WindowState' property of the figure if your version of MATLAB supports it. Otherwise, there are functions on the File Exchange you can use.
