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

for i=1:100
if rem(i-1, 5) == 0
f = figure;
end
sgtitle('WSPL zeitlicher Verlauf Modell D Teil 2');
a(i)=subplot(5, 1, rem(i-1, 5)+1);
% ...
% ... your plotting code
% ...
if rem(i-1, 5) == 4
saveas(f,sprintf('hours_%d.png',i));
saveas(f,sprintf('hours_%d.fig',i));
end
end

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.
