MATLAB: Two y axis without using plotyy

barplotplotyytwo y-axisy axis

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.
