CAPACITY LIMITS
Ploticus has these capacity limitations.
The corresponding #define is shown in parentheses.
Most are defined in pl.h or tdhkit.h and can be safely raised
if necessary (then do: make clean; make).
-
-
Default max total number of data fields (all data rows): 200,000 fields (MAXD).
This limit is dynamic and can be raised using command line option -maxfields.
-
-
Default max number of data rows: 10,000 rows (MAXDROWS).
This limit is dynamic and can be raised using command line option -maxrows.
-
-
Default maximum total number of lines in currently active procs: 5000 lines (MAXPROCLINES).
This limit is dynamic and can be raised using command line option -maxproclines.
"Currently active procs" are the current proc, any #saved procs, and any proc getdata
that have embedded data:.
-
-
Default maximum number of elements in the data vector: 100,000. This is used by proc rangebar
median computation (1 element per data point); proc lineplot, scatterplot, and curvefit (2 elements
per data point); and proc rangesweep (3 elements per data point).
-
-
Max length of a line in a ploticus script: 3000 chars before & after variable evaluation
(SCRIPTLINELEN)
-
-
Max length of variable contents: 250 chars
(VARMAXLEN)
-
-
Max length of data field: 250 chars
(DATAMAXLEN)
-
-
Max length of input data record: 2998 chars
(MAXRECORDLEN)
-
-
Max length of field names and variable names: 48 chars
(NAMEMAXLEN)
-
-
Max number of scale categories in X: 200; in Y: 200. Max total # of characters per X category set: 2500
per Y category set: 2500
(MAXNCATS, MAXCATBUF)
-
-
Max number of points from which to compute a
moving average or regression curve in proc curvefit: 5000.
Bspline curve: 100.
(see proc_curvefit.c)
-
-
Max number of pie graph slices: 80
-
-
Max number of points in polygon (including line plot w area under curve filled): 1000
(MAX_D_ROWS)
-
-
proc tabulate limits: 200 rows, 200 columns, 200 ranges, comparison significance is 38 characters.
(see proc_tabulate.c)
SYSTEM RESOURCES
By default, the max amount of CPU time allowed is 30 seconds (CPULIMIT).
This is enforced using setrlimit(), and a core dump occurs when
the limit is exceeded. This limit may be modified by using
proc settings
,
in your
config file
or by directly modifying pl.h
