Multiple y axes with multiple plots on single x axis

Dear all,
I tried to plot three y-axis where each y-axis contains two lines. I used the approach described in this post: https://nl.mathworks.com/matlabcentral/answers/459385-multiple-y-axes-on-single-x-axis#answer_372987
However, the x-ticks and y-thicks overlap each other. How can I solve this?

close all
figure
grid on
ax1 = axes;
yyaxis left
plot(theta_p{5},dW_closing_winches{5},'linewidth',1.5)
hold on
plot(theta_p{6},dW_closing_winches{6},'linewidth',1.5)
pause(0.1)
xlabel('\theta [%]','FontWeight','bold')
ylabel('Work [J]','FontWeight','bold')
ax1.XTickMode = 'manual';
ax1.YTickMode = 'manual';
ax1.YLim = [min(ax1.YTick), max(ax1.YTick)]; % see [4]
ax1.XLimMode = 'manual';
grid(ax1,'on')
ytick = ax1.YTick;
yyaxis right
plot(theta_p{5},dW_HDP{5},'linewidth',1.5)
hold on
plot(theta_p{6},dW_HDP{6},'linewidth',1.5)
ylabel('Work [J]','FontWeight','bold')
ax2 = axes('position', ax1.Position);
plot(ax2,theta_p{5},(dW_closing_winches{5}+dW_HDP{5}),'k')
hold on
plot(ax2,theta_p{6},(dW_closing_winches{6}+dW_HDP{6}),'--k')
pause(0.1)
ax2.Color = 'none';
grid(ax2, 'on')
% Horizontally scale the y axis to alight the grid (again, be careful!)
ax2.XLim = ax1.XLim;
ax2.XTick = ax1.XTick;
ax2.YLimMode = 'manual';
dW_HDP{5} = ax2.YLim;
ax2.YTick = linspace(dW_HDP{5}(1), dW_HDP{5}(2), length(ytick)); % see [2]
% horzontally offset y tick labels
ax2.YTickLabel = strcat(ax2.YTickLabel, {' '});

Take a look at these 3 lines below.
figure
grid on
ax1 = axes;
Line 1 creates a new figure.
grid on not only turns on the grid but also creates axes.
ax1 = axes creates a second set of axes directly on top of the first axes.
To fix this, move grid on to some point after the axes are created and get into the habit of always using parent handles to specify the parent of a graphics object.
fig = figure(); % GET HANDLE
% grid on % REMOVE
ax1 = axes(fig); % SPECIFY PARENT
yyaxis(ax1,'left') % SPECIFY PARENT
plot(ax1,theta_p{5},dW_closing_winches{5},'linewidth',1.5) % SPECIFY PARENT
hold(ax1,'on') % SPECIFY PARENT
grid(ax1,'on') % ADD THIS
you can do the rest :)

That's why linkprops is useful. Once the axis positions are linked, changes to one axis will copy to the second axes. Glad I could help.
