How to set a XTickLabel on a plot

I am trying to set a specific xlabel on a plot using set commands, but I can't get it to work.

The graph goes like this:

TODAY = datenum([2012 9 21 7 0 0]); REST_OF_TODAY = datenum([2012 9 21 17 0 0]); y_max1 = max([5,10]); y_min1 = min([5,10]); y_max2 = max([6 11]); y_min2 = min([6 11]);

plot(TODAY,y_max1,'--ys','LineWidth',2,'MarkerEdgeColor','r','MarkerFaceColor','g','MarkerSize',10) hold on plot(TODAY,y_min1,'--ys','LineWidth',2,'MarkerEdgeColor','b','MarkerFaceColor','y','MarkerSize',10) plot(REST_OF_TODAY,y_max2,'--ys','LineWidth',2,'MarkerEdgeColor','r','MarkerFaceColor','g','MarkerSize',10) plot(REST_OF_TODAY,y_min2,'--ys','LineWidth',2,'MarkerEdgeColor','b','MarkerFaceColor','y','MarkerSize',10) set(gca,'XTick',TODAY:REST_OF_TODAY) set(gca,'XTickLabel',{'Today','Rest of today'}) datetick('x',1) title('Wind(Knots) versus Time (dd-mmmm-yyyy)','fontsize',12,'fontweight','b'); xlabel('Time (dd-mmmm-yyyy)','fontweight','b'); ylabel('Wind (Knots)','fontweight','b'); grid minor

and I want it to write "TODAY" AND "REST OF TODAY" on the xaxis like the following.

t0 = 1 t1 = datenum([2012 9 21 7 0 0]) % 7 am today t2 = datenum([2012 9 21 17 0 0]) % 5 pm x = linspace(t1,t2); % generates a row vector y of 100 points linearly spaced between and including t1 and t2. plot(x,sin(sqrt(x-t0)*pi)) set(gca,'XTick',[t1,floor(t1)+0.5],'XTickLabel',{'Today','Rest of today'}) grid minor

Also, I would like them to be in bold

Can you please help?

format your code

... also, what do you mean by ‘can't get it to work’?

What is it doing and what do you want it to do?
