How can I earse Yticks when using Plot yyaxis

Hi, I have a problem with yyaxis function.

I just want to show different yyaxis.

When I writing on command window, it works okay. But when I run the code it makes some problems.

How can I solve this problem

====================================================source code========================================

pos2 = [0.05 0.29 0.92 0.21];

axes('Position', pos2)

plot(X_Axis_Set, Distance)

hold on

plot(Point_Index, Distance(Point_Index),'s', 'MarkerFaceColor','red', 'MarkerSize',8)

yticks('auto')

hold off

yyaxis right

plot(Point_Index, Height(Point_Index),'s', 'MarkerFaceColor','red', 'MarkerSize',8)

hold on

plot(X_Axis_Set, Height, 'LineWidth', 1)

hold off

grid on;

grid minor;

yticks('auto')

fig_title = strcat(Date_Time,' -- Distance(Left, Blue) & Height(Right, Orange)');

title(fig_title)
