How to make axis line invisible but keep ytick and yticklabel visible in double Y-axis figures

figure

x = linspace(0,10);

y = sin(3*x);

yyaxis left

plot(x,y)

ax = gca;

pause(1e-6)

set(gca,'XColor','k','YColor','k','Color','w',...

'TickLength',[0.01,0.01],'TickDir','out',...

'FontName','Times',...

'TickLabelInterpreter','Latex',...

'LineWidth',1.5,'FontSize',12.5,'FontWeight','Bold',...

'GridLineStyle','-','XGrid','on','YGrid','on');

set(gca,'Color','#EBEBEB','GridColor',[1,1,1],...

'GridAlpha',1,'GridLineWidth',1.1);

% try to hide left-Yaxis line

ax.XRuler.Axle.Visible = 'off';

ax.YRuler.Axle.Visible = 'off';

z = sin(3*x).*exp(0.5*x);

yyaxis right

plot(x,z)

ylim([-150 150])

ax = gca;

pause(1e-6)

set(gca,'XColor','k','YColor','k','Color','w',...

'TickLength',[0.01,0.01],'TickDir','out',...

'FontName','Times',...

'TickLabelInterpreter','Latex',...

'LineWidth',1.5,'FontSize',12.5,'FontWeight','Bold',...

'GridLineStyle','-','XGrid','on','YGrid','on');

set(gca,'Color','#EBEBEB','GridColor',[1,1,1],...

'GridAlpha',1,'GridLineWidth',1.1);

% try to hide right-Yaxis line

ax.XRuler.Axle.Visible = 'off';

ax.YRuler.Axle.Visible = 'off';

Hi Hongyun,

You can use the "Visible" property for each Y-axis separately to disable the axis-line. Here is an example to demonstrate how you can achieve this:

ax.YAxis(1).Axle.Visible = 'off';
ax.YAxis(2).Axle.Visible = 'off';

Note: There seems to be a bug. This is only working in MATLAB editor. Axis-line is still visible in "Live Editor". You can report it to the Technical Support team by creating a Service Request: https://mathworks.com/support/contact_us.html

Thanks, bro.
