Datetick Zoom, Pan & Subplot with Day of Year

Date formatted tick labels, auto updated when zoomed or panned with Day of Year formats added.

Description

This is an addendum to DATETICK2 which allowed time axis re-labeling when the plot is zoomed or panned. Day of Year format sets were added to the time label formats.

Example:
x = [733043:pi/10:733043+2*365];
y = sin((x-733043)/30)+rand(size(x));
figure;plot(x,y,'-o');
grid on
set(gcf,'color',[1 1 1]);
datetick2_doy('x',34);

Then zoom or pan as needed and the time axis will update the tick marks.
