First let me recommend this free book, and this web page that I will follow almost literally. And note the sweet menu at the top-right corner of the graph. Title="Air passengers" file='line1.html'. !lineplot passengers / x=yearMonth xnumeric=0 Strings that are not hard-coded (like the title of the graph passed as an argument to the macro) need to be stored in every record, even if you need them only once. I use AGGREGATE with MODE=ADDVARIABLES to store the number of records in each record and then compare $CASENUM with that number.
Likewise, for the stuff that follows the data, you need to know which is the last record.
#Pspp syntax editor code#
You can write all the stuff that needs to be written first (like the html code in the macro) by filtering DO IF $CASENUM EQ 1. WRITE writes the strings and variables you supply for every record in the active file. It does not integrate with pspp’s output but instead, with pspp’s WRITE command, creates a separate html file with code and data for a Vega-Lite graph. The closest you get is with a bar chart: GRAPH /BAR = MEAN(passengers) BY yearMonth.

When working with time series you want to look at the data with line plots, which unfortunately PSPP does not sport at the moment.
Some housekeeping for formats and to create a variable for the time series labels: VALUE LABELS month 1 'Jan' 2 'Feb' 3 'Mar' 4 'Apr' 5 'May' 6 'Jun'ħ 'Jul' 8 'Aug' 9 'Sep' 10 'Oct' 11 'Nov' 12 'Dec'.ĬOMPUTE yearMonth = CONCAT( STRING(year, F4.0), '-', STRING(month, N2.0)).įORMATS year (F4.0) month (F2.0) passengers (F3.0). Now transform this into long format with XSAVE: VECTOR m = Jan TO Dec. Don’t think I type in all those commands just like that! After almost every command I run PSPP with the syntax up to that point: In what follows, at times I show big chunks of syntax. year Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec (F4.0).
