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
