Hello, below you can see the structure of my plot. At the moment Im using the same y axis for every plot but I want to use two different y axis. One for the bar plot (patch...) and a second one for the other plots. How can i do this?
f(8) = figure('Units','pixels',...
'position',[fLeft fBottom fWidth fHeight],...
'PaperType','A4',...
'PaperOrient','portrait',...
'PaperPositionMode', 'manual');
set(gcf, 'color', GrayLight);
set(gcf, 'InvertHardCopy', 'off');
AxH = axes('NextPlot','add');
for k1 = 1:size(...)
hLine=patch(...);
end
plot(...,...)
hold on
grid on
datacursormode on
title(...)
xlabel(...)
ylabel(...)
xlim(...)
ylim(...);
plot(...,...)
hold on
plot(...,...)
legend({'...'},...
'Position',[....
'FontSize',LegendFontSize,...
'Color',Gray);
xTick=...
set(gca,'Color',GrayLight, 'XTick', xTick);

Create two axes. For the top axes set the YAxisLocation to right, the Color to none, and NextPlot to replacechildren.
For example:
>> ax1 = axes();
>> ax2 = axes('YAxisLocation','right','Color','none','NextPlot','replacechildren');
>> plot(ax1,0:3,0:3)
>> plot(ax2,0:3,sqrt(0:3))
giving:

Do not use gcf and gca: always obtain and use the explicit handles for all graphics objects that you need to refer to.

Not all versions of MATLAB allow the first input argument of patch to be an axes handle. To know what your installed version does always refer to the installed help, not the online help. Note that you can provide the axes handle as a Name-Value input argument:
patch(...,'Parent',ax1)
For example:
>> axh = axes();
>> patch([0,0.5,1],[0,1,0],1,'Parent',axh)
generates this:
