how to plot series of y-axis that only on single point of x-axis?

Hi al:
i want to plot series of data but at y-axis i have more than one ponit and at x-axis i have one ponit for exampe.
at x-axis i have
ax.XTick = [ 1 2 3 4 5 6 7 8 ];
ax.XTickLabels = {'07:00AM','08:00AM','9:00AM','10:00AM','11:00AM','12:00PM','1:00PM}','2:00PM'};
ax.XTickLabelRotation = 45;
now i want plot these points y1=[12 13 15 16] on x-axis fix point which is 07:00AM
y2=[123 44 555 324 643 332] on x-axis fix point which is 08:00AM
y3=[32 45 53 67 86 98 67] on x-axis fix point which is 09:00AM
y4=[77 88 99 45 32 333 44 555 666] on x-axis fix point which is 01:00PM.
thanks

ax.XTick will only set the ticks values along the x-axis. What is the actual range of x?
As far as I can assume the values of x:
x=[1:8];
y1=[12 13 15 16];
...
...
...
... and so on
plot(x(1),y1, "--o", x(2), y2,"--o", x(3), y3,"--o", x(4), y4,"--o"); % similarly for x(5), y5 to x(6) to y6
xticks([ 1 2 3 4 5 6 7 8 ])
Xticklabels({'07:00AM','08:00AM','9:00AM','10:00AM','11:00AM','12:00PM','1:00PM','2:00PM'});
The code can be improved if you use loops and combine all the y values in a single matrix (cell arrays).

hi Durganshu Mishra:
if we have large file and we want plot it against X-axis how we can easly plot it.
for example i have hourly expenses daily and i want plot it in graph for whole the year so i am asking if i nominat every day and than plot it against x-axis it will be very hard inmatlab.
thanks

You'll have to process the file and store all the information in form of variables. Then you can proceed in the same way and obtain the plots. With an incresed size and large database, the job may become a bit tedious but it'll be done easily if you keep the track of variables and plot them accordingly.
