Labeling using datetick on a scatter plot?

Hello,
I am trying to do a scatter plot with labels of each point's value. The trick here is using datenum to get values for the x-axis using datetick. Prior to this I just used a for loop to obtain the position of each point, and num2str(...) for each point's numerical quantity. However, using datenum/datetick, the code below does not properly identify the position of each point properly.
Example:
f3=figure(3);
set(f3,'Units','normalized','Position',[0.1 0.1 0.65 0.85]);
h5=scatter(dnums,NOXPHghtMeso2,TimeOnes2,NOXPVortM2,'filled');
datetick('x',13)
h6=colorbar('peer',gca);
set(get(h6,'ylabel'),'String','x 10^-^3 ','Fontweight','bold','FontSize',12)
hold on
for idx2=1:max(size(NOXPTimeM2))
text(dnums(idx2),NOXPHghtMeso2(idx2)+0.05,num2str(NOXPVortM2(idx2)))
end
hold off
%where dnums is calculated from:
for idx=1:max(size(NOXPHghtMeso2))
tmp_str=char(num2str(NOXPHghtMeso2(idx)));
if(idx>1)
if(M2hrs(idx)<M2hrs(idx-1))
day=day+1;
end
end
dvec=[2010 05 day M2hrs(idx) M2min(idx) M2sec(idx)];
dnums(idx)=datenum(dvec);
end
I have been struggling to figure out a conversion that the plot will recognize to line up the x-position with datetick, but nothing comes to mind. Is there a means of doing this?
Thanks,
Chris

Nevermind. I figured out the solution. Thanks anyways!
