How to add a 'No Data' label on a Bar plot

I already got my bar plot like the picture below but how do I display 'No data' on it

like in this picture this is my code, thank you.

month = {'Jan', 'Feb', 'Mar', 'Apr', 'Mei', 'Jun', 'Jul', 'Ogos','Sep', 'Okt', 'Nov', 'Dis'};
GPS =[35.5 71.4 77.4 70 35.5 36.7 22.6 9.7 13.3 NaN NaN 6.5];
SucRate= [12.9 64.3 71 66.7 25.8 23.3 22.6 0 0 NaN NaN 0];
Solar = [137.2 126 125.1 129.9 122.6 130.8 110.5 109.2 103.1 104.1 107.2 109.2];
yyaxis left
b = bar(GPS,'FaceColor',[0.2 0.2 0.5]);
hold on
b1= bar(SucRate,'FaceColor',[0 0.7 0.7]);
ylim([0 100]);
yyaxis right
p = plot(Solar,'-.ko');
ylim([100 170]);
set(gca, 'xticklabel', month )
xlabel('Bulan')
yyaxis left
ylabel('Kadar Kejadian Bulanan (%)','Color','k')
yyaxis right
ylabel('Purata Bulanan Fluks Suria F10.7','Color','k')
ax = gca;
ax.YAxis(1).Color = 'k';
ax.YAxis(2).Color = 'k';
p.LineWidth = 2;
t= text(11,160,'2015');
t(1).FontSize = 18;
legend({'Hari Kejadian','Hari Kejadian Berturutan','Fluks Suria F10.7'},'Location','northeast');

Add something like the following at the end of your code

text(10,102,'No Data','Rotation',90)
text(11,102,'No Data','Rotation',90)
