Two y axis without using plotyy

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.

https://www.mathworks.com/help/matlab/ref/matlab.graphics.axis.axes-properties.html

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.

How can I create two axis?

[Stephen23]

"How can I create two axis?"

Exactly like I showed you in my answer: my answer has just four lines of code. Did you look at them? The first two lines create two axes, by calling axes twice. The next two lines plot data on those two axes.

Thanks, your example is running. But how can I do this with the patch function above? When I write patch(ax1,...) I get an error that vectors must be the same length..

[leonidas86]

It works with 'Parent', ax1

[Stephen23]

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:
