How to plot partial results of a for-loop in one figure and create different figures for other results?

I have a for loop, which reads in and evaluates the run-off values for various years. There are several time series for each year. So I have an ensemble of time series per year. Now I want to create a figure for each year, in which the respective ensemble is presented.
The following code section shows the plot function for the year 2014 as an example:
sdatelim=[datenum(2014,05,01) datenum(2014,10,01)];
dt = 1/24;
sdate2014 = sdatelim(1):dt:sdatelim(2);
figure('Position',[200 100 900 900],'PaperPositionMode','auto','Color','w');
a(1) = axes;
set(a(1),'Position',[0.09 0.09 0.80 0.80],'fontsize',13)
hold on;
plot(sdate2014(1:3672),Qs2014,'.'); hold on;
% the next figure for the subsequent year
... figure(...); hold on;
a() = axes ...
plot (sdate2015(1:3672),Qs2015); hold on;
Regardless of whether I add the figure command before the loop or add the hold on, always a separate figure is opened.
This is a solution that did not work.
Now my questions are:
  1. How can I create multiple figures with the corresponding ensemble (that means e.g. all time series for the year 2014 in one figure)?
  2. How can I change the line color within a figure for a few thousand ensemble members?

I don't get it. You are not using the ii index inside the loop. Is Qs2014 a 2D array?
If so:
subplot(2,1,1)
plot(sdate2014(1:3672),Qs2014,'Color',rand(1,3));
subplot(2,1,2);
plot(sdate2015(1:3672),Qs2015,'Color',rand(1,3));
Have you tried reading the documentation? It's pretty good --- most of the time.

@José-Luis: Thanks, now it works. I have incremented the subplot-handle-number manually, without a for-loop.
For three graphics, this is the easiest solution. I have read the documentation on mathworks.com.
My implementation is:
dt = 1/24;
sdatelima=[datenum(2014,05,01) datenum(2014,10,01)];
sdate2014 = sdatelima(1):dt:sdatelima(2);
sdatelimb=[datenum(2015,05,01) datenum(2015,10,01)];
sdate2015 = sdatelimb(1):dt:sdatelimb(2);
sdatelimc=[datenum(2016,05,01) datenum(2016,10,01)];
sdate2016 = sdatelimc(1):dt:sdatelimc(2);
aH(1) = subplot(3,1,1); hold on;
set(aH(1),'TickDir','out','FontSize',12);
set(gcf,'Renderer','painters');
datetick('x','keeplimits');
ylim([0 20])
xlim(sdatelima)
title(aH(1),'Runoff 2014 - MCS (Ensemble)','fontsize',14,'fontweight','b');
ylabel(aH(1),'Runoff [m^3 s^-^1]','fontsize',13)
xlabel(aH(1),'Date','fontsize',13)
box on;
grid on;
plota = plot(sdate2014(1:3672),Qs2014,'Color',rand(1,3)); hold on;
set(plota,'LineWidth',2.0)
aH(2) = subplot(3,1,2); hold on;
set(aH(2),'TickDir','out','FontSize',12);
set(gcf,'Renderer','painters');
datetick('x','keeplimits');
ylim([0 20])
xlim(sdatelimb)
title(aH(2),'Runoff 2015 - MCS (Ensemble)','fontsize',14,'fontweight','b');
ylabel(aH(2),'Runoff [m^3 s^-^1]','fontsize',13)
xlabel(aH(2),'Date','fontsize',13)
box on;
grid on;
plotb = plot(sdate2015(1:3672),Qs2015,'Color',rand(1,3)); hold on;
set(plotb,'LineWidth',2.0)
aH(3) = subplot(3,1,3); hold on;
set(aH(3),'TickDir','out','FontSize',12);
set(gcf,'Renderer','painters');
datetick('x','keeplimits');
ylim([0 20])
xlim(sdatelimc)
title(aH(3),'Runoff 2016 - MCS (Ensemble)','fontsize',14,'fontweight','b');
ylabel(aH(3),'Runoff [m^3 s^-^1]','fontsize',13)
xlabel(aH(3),'Date','fontsize',13)
box on;
grid on;
plotc = plot(sdate2016(1:3672),Qs2016,'Color',rand(1,3)); hold on;
set(plotc,'LineWidth',2.0)
Thanks for your help!
