I have this hypothetical datasets and i am trying to generate the conc*time. I need day 1 time start from the 0-96 hr  (x-axis), then need a gap on x-axis for Day 2 and then start day 3  time 0 to 96 hr on x-axis.

Here is what i did, i converted the day 2 and day 5 time by multiplying time by 24 hr. This gave me continuous time from 0 to let say 234 (dont quote on this) hr and plot the data using the below code.The problem is plot gave me x-axis tick 0-234, as expected. However, I need x-axis tick 0-96 (day1), day2, 0-96 (day5).

goption reset=global;

axis1 value=(font=swissb h=0.2800 cm)

label=(font=swissb h=0.2800 cm "Time (hr)")

offset=(2 pct,)

minor=none

order=(0 to 240 by 12);

axis2 value=( font=swissb justify=right h=0.3000 cm)

offset=(2 pct,)

minor=none

logbase= 10

/*order=(0 to 1200 by 100)*/

label=(font=swissb angle=90 h=0.4800 cm " Concentration (ng/mL)");

proc gplot data=B;

PLOT conc*time /  HAXIS=AXIS1 VAXIS=AXIS2 nolegend noframe des="" skipmiss;

symbol1 c=black interpol=joine l=1 w=1 r=1;

run;

Thanks
