PLOT88 Function Summary

PLOTS: initializes the PLOT88 package.
PLOT: generates straight line segments from the current "pen" position to the specified position with the "pen" up or down.
PLOTD: generates straight, dashed line segments from the current "pen" position to the specified position.
STDASH: defines the characteristics of a dashed line.
OFFSET: defines the X & Y offset and scaling values.
FACTOR: defines drawing enlargement or reduction.
WINDOW: defines the location of the "drawing" window.
ROTTRN: rotates and translates the drawing on the output device.
WINORG: defines multiple windows to be drawn on one page.
NEWPEN: specifies the line width.
WHERE: returns the current (x,y) "pen" position and drawing scaling factor.
COLOR: defines the color index to be applied to lines and text.
PALETE: defines the color associated with the color index.
SYMBOL: draws characters and special centered symbols in two or three dimensions.
ASPECT: defines the width-to-height ratio of characters drawn by SYMBOL and NUMBER.
CHPATH: defines symbol character path (horizontal or vertical).
GETWID: returns the length of a character string.
NUMBER: converts a real number to a decimal equivalent character string and draws the string in two or three dimensions.
GETNUM: converts a single precision real number to its decimal equivalent as a character string.
FONT: selects a character set by its number.
IBMPLX: selects the IBM character set.
SIMPLX: selects the simplex character set.
DUPLX: selects the duplex character set.
COMPLX: selects the complex character set.
TRIPLX: selects the triplex character set.
SCRPLX: selects the script character set.
GRKPLX: selects the Greek character set.
SCALE: scans an array to determine its maximum and minimum values for use by LINE, CURVE, and AXIS.
LINE: a set of (x,y) points are drawn in two dimensions with optional straight lines between the points and an optional centered symbol at each point.
CURVE: draws a smooth line in two dimensions between a set of (x,y) points.
AXIS: draws a linear axis line with title, tic marks, and tic labels in two dimensions.
STAXIS: defines the format of axis tic annotation, axis title, and tic length.
STLINE: defines the line type and centered symbol characteristics used by LINE and LGLIN.
SCALG: determines the logarithmic scale factors for use by LGAXS and LGLIN.
LGAXS: draws a logarithmic axis in two dimensions with title, tics, and tic labels.
LGLIN: draws a log-log or semi-log line in two dimensions between a set of (x,y) points.
FILL: provides shading of polygonal areas.
STFILL: selects the shading pattern used by FILL.
DFFILL: defines the fill pattern used by FILL.
ZGRID: performs two-dimensional (surface) interpolation to construct a grid of (x,y) points using La Placian and spline interpolation.
DGRID: performs two dimensional (surface) interpolation to construct a grid of regularly spaced points using 1/(distance to a power).
ZSMTH: smooths the gridded data.
ZSIDE: determines if a point is inside a polygon. Used when placing title blocks inside a contour map.
ZLEVEL: determines all contour levels present on a map.
ZPOST: marks and labels randomly spaced data points on the contour map (two-dimensional contours only).
ZCNTUR: draws the two or three dimensional surface contours based on a grid of control points.
ZCSEG: draws the two or three dimensional surface contours based on a grid of control points. Divides the grid into smaller areas for more precise contouring.
CCNTUR
DISP3D: defines the drawing spatial representation (two or three dimensions).
SCAL3D: defines the dimensions of the grid array in world units.
SYORNT: defines the drawing angle path for text and axis.
P3D2D: converts a point in three dimensions into its corresponding position on the output device. This routine is used to place annotation on the mesh surface drawing.
FIT3D: defines the three-dimensional space that will fit in the output two-dimensional window. Used when drawing a three-dimensional curve. No mesh surface is drawn.
AXIS3D: draws a linear axis line with title, tic marks, and tic labels in two dimensions.
LINE3D: draws a line in three dimensions with hidden line processing.
VISP3D: indicates if a point is visible after a mesh surface is drawn.
MESH: defines the three-dimensional to two-dimensional transform and draws the three-dimensional mesh surface based on the grid of control points. No subgridding is performed.
MESHS: defines the three-dimensional to two-dimensional transform and draws the three-dimensional mesh surface based on the grid of control points. Each grid square is subsectioned to produce 2, 4, 8, or 16 mesh lines.
MESH4: draws a four dimensional mesh surface. The fourth dimension is shown as color on the surface. No subgrdiding is performed.
MSQUAL: defines the mesh surface line quality for plotter output.
MESHCI: defines the two color indexes used in drawing the mesh surface top and underside.
MSHCOL: defines the color contouring intervals used in drawing a mesh surface.
UsePrinter88: defines the printer to receive the PLOT88 output.
JobTitle88: assigns a title to the drawing in the print spool queue.
