How to disable Subplot XtickLabel designed with App Designer

I would like to disable the Xticklabel for the first subplot, and only the Xticklabel only visible on the second subplot.

However, upon plot, I notice the Xticklabel still visible despite having the following config.

fig=SomethigDesignUsingAppDesigner
fig.UIFigure.AutoResizeChildren = 'off';
ax1 = subplot(6,1,1,'Parent',fig.UIFigure,'XTickLabel',[]);
ax2 = subplot(6,1,2,'Parent',fig.UIFigure);
plot(ax1,[1 2 3 4],[100 90 40 70])
plot(ax2,[1 2 3 4],[11 91 4 7])

Appreciate if someone can shed some light about this problem

have you tried update ax1 XTickLabel after the plot?

add ax1.XTickLabel = ''; after your plot line and see.
