SYSTEM LIMITS

This section documents some relevant limits when using Dataplot. Note that many of these limits can be set (in the file DPCOPA.INC) before Dataplot is compiled on a specific system. The limits below are the default values, but the limits for your specific system may be set differently.

  1. MAXOBV = 1,500,000

    Defines the maximum number of observations for a single variable. This is the parameter most likely to be modified before Dataplot is compiled. It will typically be in the range 100,000 to 1,500,000.

  2. MAXOBW = 10*MAXOBV

    Defines the total size of the data work space. Note that the DIMENSION command can be used to re-allocate between rows and columns with the restriction that the maximum number of rows cannot exceed MAXOBV.

  3. MAXPOP = 2*MAXOBV

    Defines the maximum number of points on a plot.

  4. MAXNME = 50000

    Define the maximum number of names (variables, parameters, strings, matrices).

  5. MAXSTR = 255

    Defines the maximum number of characters in a single command line.

  6. MAXEDC = 24*MAXOBV

    Defines the maximum number of characters that the EDIT/FED command can accomodate.

  7. MAXEDL = 25000

    Defines the maximum number of lines for the EDIT/FED command.

  8. MAXCMP = 35

    Defines the maximum number of coefficients in multilinear regression.

  9. MAXLIS = 200 MAXCIS = 255

    Define the maximum number of lines/columns in the LIST/SAVE table.

  10. MAXLIL = 20000
    MAXCIL = 255

    Define the maximum number of lines/columns in the LOOP table.

  11. MAXLIP = 20

    Define the maximum number of lines in the REPLOT table.

  12. MAXPM = 200

    Define the maximum number of pixmaps that can be saved.

  13. MAXTOM = 46*MAXOBV/3

    Define the maximum size (rows times columns) for a matrix. Note that the DIMENSION MATRIX command can be used to specify the allocation between rows and columns in the matrix.

  14. Define the following plot control component dimensions:

      MAXTC = 100 = the maximum number of tic marks on an axis.
      MAXLG = 100 = the maximum number of legends.
      MAXBX = 100 = the maximum number of boxes.
      MAXAR = 100 = the maximum number of arrows.
      MAXSG = 100 = the maximum number of segments.
      MAXLN = 100 = the maximum number of line traces.
      MAXCH2 = 100 = the maximum number of character traces.
      MAXFL = 100 = the maximum number of region fills.
      MAXPT = 100 = the maximum number of patterns.
      MAXSP = 100 = the maximum number of spikes.
      MAXBA = 100 = the maximum number of bars.
      MAXRE = 100 = the maximum number of regions.
      MAXTX = 100 = the maximum number for the text command.
      MAXSUB = 10 = the maximum number of subregions.
      MAXGRP = 5 = the maximum number of group label variables.
      MAXGR2 = 40 = the maximum number of characters for a group label.
      MAXGLA = MAXOBV/100 = the maximum number of levels for a group label.
      MAXCNL = 100 = the maximum number of contour labels.

  15. MAXCH = 200

    Define the maximum number of characters in a text string for a title or label.

  16. MAXLG2 = 200

    Define the maximum number of characters in a legend.

  17. MAXF1 = 50,000

    Define the total number of characters for all strings/functions.

  18. MAXF2 = 500

    Define the maximum number of strings/functions.

  19. MAXF3 = 500

    Define the maximum number of characters printed for the last model fitted.

  20. MAXRCL = 9999

    Define the maximum number of characters that can be read from a single record in a data file.
