how to plot time series by multiple categories of variable

[viollete]

Hello,

I have day-by-day number of admission (variable1) per hospital (variable2) and want to plot time series for a year for each hospital.

How could I do it?

Thank you

Here is link to a similar graph using Proc SGPlot: 52964 - Create a spaghetti plot with the SGPLOT procedure

Hopefully day-by-day means you have a date variable, preferably a SAS date valued variable. Use your date variable for the X=, Y= number of admissions and group=hospital.

A BY statement with a Year variable would be easiest to get a graph per year.

Or Proc SGPanel could work as well similar to 35167 - Sales figures for 1993 by product ignoring the VBAR part of the code
