libploticus(3) C language API IMPORTANT BASICS APPROACHES There are two approaches to using ploticus: Prefabs are easy to use and a quick way to produce certain standard types of graphs. Ploticus scripts offer greater power and flexibility, but have a steeper learning curve. PREFABS
Standard prefab parameters chron - display chronological data dist - frequency distribution histograms lines - line plots pie - pie graphs scat - scatterplots with correlations stack - stacked bar graphs vbars - bar graphs draw - interpret ploticus draw commands multidist - multiple, overlaid frequency distributions SCRIPTS
Using procs and attributes; #proc, #procdef, #saveas, #clone Syntax and variables Flow of control directives such as #set and #if Using #shell and #sql Functions - essential to getting the most out of ploticus scripts Reserved variables Script examples: Index PNG thumbnails GIF thumbnails PLOTTING PROCS proc annotate - add annotation 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 categories - define a set of categories for an axis 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 rangebar - produce a rangebar / boxplot 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 vector - vector plots
