https://communities.sas.com/t5/Graphics-Programming/Plot-Date-Interval/m-p/8892#M63 Hello,<BR /> I have data on days individuals perform an activity set up as follows:<BR /> <BR /> Individual Start Date End Date Total Days <BR /> 1 10/15/2005 10/18/2005 4 <BR /> 2 11/7/2005 11/30/2005 23 <BR /> 3 12/1/2005 12/2/2005 2<BR /> <BR /> I would like to create a plot where along the x axis we have consecutive days and along the y axis the date interval the activity is being performed. For each individual we would have a response of 1 on dates the activity takes place and 0 when it doesn't, then sum across all individuals for each day. That is, if 20 individuals are active on 11/7, then the y-value is 20 etc. Unfortunately, I am having trouble getting the data set up in a way to do this. Does anybody have any suggestions?
