The pl(1) command produces plots from scripts, eg: pl -png scat1.pl Gallery of script examples What's new Quick start
2. Write your script using your favorite text editor (peruse the script examples gallery to find examples) 3. Execute the pl command (pl scriptfile) Writing scripts
Script syntax Specifying procedures and attributes Variables Directives #proc #endproc #procdef #saveas #clone #set #setifnotgiven #call #if #ifspec #for #while #loop #break #continue #exit #include #cat #return #write #shell #sql System variables Plotting procs
proc areadef - define a plotting area notes on automatic scaling proc axis (xaxis/yaxis) - render an axis proc bars - bar graphs, histograms, error bars, floating bars, timelines proc boxplot - produce a boxplot proc categories - define a set of categories for an axis proc catlines - a set of lineplots, one per category proc curvefit - generate a curve from data points proc drawcommands - draw using command set proc getdata - get or specify plot data proc legend - render a legend proc line - draw arbitrary lines proc lineplot - produce a line plot proc page - set page-wide attributes/ break page proc pie - produce a pie graph proc rangesweep - produce a range sweep proc rect - draw an arbitrary rectangle proc scatterplot - produce a scatterplot or grid or data point display proc settings - overall settings for units, notations, etc proc tree - draw a rooted tree diagram from newick data proc vector - vector plots proc venndisk - venn diagrams Utility procs
proc image - incorporate an image (eg. a logo) proc legendentry - define a legend entry explicitly proc print - show outliers, contents of variables, etc. (deprecated) proc processdata - internal processing of data: - accumulate - break processing - count/summate on instances - joins - row numbering - compute percents - reverse row order - rotation of row/column matrix - find mean, sd, min, max - compute totals proc symbol - render a single data point symbol proc tabulate - perform tabulations & frequency distributions proc trailer - specify data at end of script proc usedata - set the current data set for plotting Functions
