   time=[0:2:24];
   data=[23.3;21.68;27.47;41.98;60.13;76.10;75.13;66.050;54.027;32.78;24.62;22.67;23.38];
   figure;
   plot(time,data,'r','LineWidth',2)
    title('station','fontsize',12,'fontweight','bold')
     xlabel('UTC','fontsize',12,'fontweight','bold')
     ylabel('data','fontsize',12,'fontweight','bold')
   set(gca, 'XTick',time, 'FontSize',12); grid on

%in y axis of figure, I need to see all data values w.r.t. time. Like, 23.3 for 0, 21.68 for 2 hours, etc. I also need to narrow the data space of the y axis. i.e, in this plot, increment of data is 10, can I set 5 something?

Hi, to narrow the data space you can use the following commands,

    ax=gca;
    ax.YLim = [20 78];
    ax.YTick = 20:2:78;

ax.Ylim is setting the limits of the y-axis and ax.YTick sets the distance between the Ticks.

To display the data values you could use the text function.

text(x,y,str)

hi, I used your command but it gives me this warning;

Warning: Struct field assignment overwrites a value with class "double". See MATLAB R14SP2 Release Notes, Assigning Nonstructure Variables As Structures Displays Warning, for details.

And there is no changes happened.
