Increase only the axes line width and not the grid line-width

Hello, I having problems adjusting just the line-width of the axes in my surface. the only code I've seen is

set(gca,'linewidth', 2,'fontsize',60,'fontname','Times New Roman') % Sets the width of the axis lines, font size, font

here is my relevant code:

        s2 = surf(EnergyAlpha, TimeDelayAlpha, AbsorbanceChangeAlpha); % Creates a surfurace of the values in the postive quadraunt of the x,y,z

        hold

        s1 = surf(EnergyBeta, TimeDelayBeta, AbsorbanceChangeBeta); % Creates a surfurace of the values in the negativ quadraunt of the x,y,z

        % Use this for WS2image and PerovskiteImage
        %xlim([1.8 2.7]); % Limist the x axis
        %ylim([-1.4 100]); % Limist the y axis
        %zlim([-3.7 4.3]); % Limist the z axis

        % Use this for WS2-Perovskite-image
        xlim([1.8 2.7]); % Limist the x axis
        ylim([-1.4 100]); % Limist the y axis
        zlim([-2 5.8]); % Limist the z axis

        colorbar('Position', [0.95 0.1 0.01 0.7])

        az = 220;
        el = 30;
        view(az, el);

        %title(fileName, 'fontsize',25) % Title label
        %xlabel('Photon Energy (eV)', 'fontsize',20) % x-axis label
        %ylabel('Time-Delay (ps)', 'fontsize',20) % y-axis label
        %zlabel('Absorbance Change', 'fontsize',20) % z-axis label

        get(gca,'fontname')  % shows you what you are using.
        set(gca,'linewidth', 2,'fontsize',60,'fontname','Times New Roman') % Sets the width of the axis lines, font size, font
        shading interp

and here is a picture of my surface:

What exactly is the "axes line width"? Do you mean the 3 black lines in X, Y and Z direction?

[Leo Quintanar]

yes how to make the x, y and, z

Answer 1

[Walter Roberson]

There is an undocumented property you can use:

ax = gca;
ax.XRuler.Axle.LineWidth = 2;

[Lhoussine BENTAYFASTE]

thank you verry much

that's working perfectly

i was looking about it for a long time

thanks again

Answer 2

[Star Strider]

The only way I know to do that is to overplot the axes lines using plot3 (or plot in 2D).

Try this:

[X,Y,Z] = peaks;

figure(1)
surf(X,Y,Z)
xl = xlim;
yl = ylim;
zl = zlim;
hold on
plot3(xl,[1 1]*yl(1),[1 1]*zl(1), 'k', 'LineWidth',2)
plot3([1 1]*xl(1),yl,[1 1]*zl(1), 'k', 'LineWidth',2)
plot3([1 1]*xl(1),[1 1]*yl(2),zl, 'k', 'LineWidth',2)
hold off
grid on

If you rotate the plot significantly, you will need to re-plot the wider axis lines.
