D.8 . PROGRAM PLOTEB : PLOTTING UTILITY 415D.8 Program PLOTEB : Plotting UtilityProgram PLOTEB creates video and hardcopy plots of skin friction, cf,or Stanton number, St, versus arc length, s, and a u+ versus y+ velocityprofile computed with Program EDDYBL on IBM PC's and compatibles .Input-parameter description :Program PLOTEB reads the following sixteen input parameters fromdisk file ploteb .dat in the order listed below . Integer quantities mustbe formatted according to (7x,i6) while floating-point quantities must beformatted as (7x,f6 .2) .mon Monitor type (see Appendix E)ifore Foreground color (see Appendix E)iback Background color (see Appendix E)nprin Printer type (see Appendix E)mode Graphics-mode flag for printers ; number of pens for plotters (seeAppendix E)metric Input arc length units flag-1 Input arc length is in meters0 Input arc length is in feet1 Convert from feet to metersideccf Number of decimal places for cf/St scaleidecx Number of decimal places for arc length scaleidecup Number of decimal places for u+ scaleisymb Symbol type for experimental data points0 Circle1 Triangle2 Square3 Diamondjstart Number of cf/St points to skip over at beginning of computation ;this is sometimes useful in order to skip over transient behavior atthe beginning of a computation. The sign also determines whatis plotted .> 0 Plot cf versus s< 0 Plot St versus skcyccf Increment between points to be plotted for cf/St versus skcycup Increment between points to be plotted for u+ versus y+kfilt 0 to suppress data filtering ; otherwise use filtering . The filteringalgorithm generates a smoothed curve .ksize Plot scaling factor . Using 100 yields a full-size hardcopy plot .Smaller values yield a hardcopy plot reduced by ksize per cent .
