I am producing a stacked VBAR with SGPLOT (replicating a GCHART) with 24 hours of 5 minute interval data on zOS SAS 9.4 TS1M4. I only want to display hourly values on the XAXIS (ie: 1, 2, 3,...23) but SGPLOT wants to display a value for each 5 minute time value. Based on other answers I tried createing a tick format with VALUE entries for each hourly time value ('01:00:00't ... '23:00:00't) translating to a value and OTHER='' and then using the VALUESFORMAT= option on the XAXIS statement but that did not work and the chart displayed unreadable values for each bar.
proc sgplot data=vmlpar; by sysid; vbar time / response=lnxbusy fill group=vmduser grouporder=ascending stat=sum; xaxis label='Time of Day' valueattrs=(blue) valuesformat=tick.;
Since you are using SAS 9.4m3 or greater, try adding TYPE=TIME to your XAXIS statement and see if you get what you want. You can also control the intervals displayed by using the INTERVAL option on the XAXIS statement.
Hope this helps!
