PLW3D(3plplot) PLplot API PLW3D(3plplot) NAME
plw3d - Set up window for 3-d plotting SYNOPSIS
plw3d(basex, basey, height, xmin, xmax, ymin, ymax, zmin, zmax, alt, az) DESCRIPTION
Sets up a window for a three-dimensional surface plot within the currently defined two-dimensional window. The enclosing box for the sur- face plot defined by xmin, xmax, ymin, ymax, zmin and zmax in user-coordinate space is mapped into a box of world coordinate size basex by basey by height so that xmin maps to -basex/2, xmax maps to basex/2, ymin maps to -basey/2, ymax maps to basey/2, zmin maps to 0 and zmax maps to height. The resulting world-coordinate box is then viewed by an observer at altitude alt and azimuth az. This routine must be called before plbox3(3plplot) or plot3d(3plplot). For a more complete description of three-dimensional plotting see the PLplot documenta- tion. Redacted form: plw3d(basex, basey, height, xmin, xmax, ymin, ymax, zmin, zmax, alt, az) This function is examples 8,11,18,21. ARGUMENTS
basex (PLFLT, input) The x coordinate size of the world-coordinate box. basey (PLFLT, input) The y coordinate size of the world-coordinate box. height (PLFLT, input) The z coordinate size of the world-coordinate box. xmin (PLFLT, input) The minimum user x coordinate value. xmax (PLFLT, input) The maximum user x coordinate value. ymin (PLFLT, input) The minimum user y coordinate value. ymax (PLFLT, input) The maximum user y coordinate value. zmin (PLFLT, input) The minimum user z coordinate value. zmax (PLFLT, input) The maximum user z coordinate value. alt (PLFLT, input) The viewing altitude in degrees above the XY plane. az (PLFLT, input) The viewing azimuth in degrees. When az=0, the observer is looking face onto the ZX plane, and as az is increased, the observer moves clockwise around the box when viewed from above the XY plane. AUTHORS

PLENV0(3plplot) PLplot API PLENV0(3plplot) NAME
plenv0 - Same as plenv(3plplot) but if in multiplot mode does not advance the subpage, instead clears it. SYNOPSIS
plenv0(xmin, xmax, ymin, ymax, just, axis) DESCRIPTION
Sets up plotter environment for simple graphs by calling pladv(3plplot) and setting up viewport and window to sensible default values. plenv0(3plplot) leaves enough room around most graphs for axis labels and a title. When these defaults are not suitable, use the individual routines plvpas(3plplot), plvpor(3plplot), or plvasp(3plplot) for setting up the viewport, plwind(3plplot) for defining the window, and plbox(3plplot) for drawing the box. Redacted form: plenv0(xmin, xmax, ymin, ymax, just, axis) This function is used in example 21. ARGUMENTS
xmin (PLFLT, input) Value of x at left-hand edge of window (in world coordinates). xmax (PLFLT, input) Value of x at right-hand edge of window (in world coordinates). ymin (PLFLT, input) Value of y at bottom edge of window (in world coordinates). ymax (PLFLT, input) Value of y at top edge of window (in world coordinates). just (PLINT, input) Controls how the axes will be scaled: -1: the scales will not be set, the user must set up the scale before calling plenv0(3plplot) using plsvpa(3plplot), plvasp(3plplot) or other. 0: the x and y axes are scaled independently to use as much of the screen as pos- sible. 1: the scales of the x and y axes are made equal. 2: the axis of the x and y axes are made equal, and the plot box will be square. axis (PLINT, input) Controls drawing of the box around the plot: -2: draw no box, no tick marks, no numeric tick labels, no axes. -1: draw box only. 0: draw box, ticks, and numeric tick labels. 1: also draw coordinate axes at x=0 and y=0. 2: also draw a grid at major tick posi- tions in both coordinates. 3: also draw a grid at minor tick positions in both coordinates. 10: same as 0 except logarithmic x tick marks. (The x data have to be converted to logarithms separately.) 11: same as 1 except logarithmic x tick marks. (The x data have to be converted to logarithms separately.) 12: same as 2 except logarithmic x tick marks. (The x data have to be converted to logarithms separately.) 13: same as 3 except logarithmic x tick marks. (The x data have to be converted to logarithms separately.) 20: same as 0 except logarithmic y tick marks. (The y data have to be converted to logarithms separately.) 21: same as 1 except logarithmic y tick marks. (The y data have to be converted to logarithms separately.) 22: same as 2 except logarithmic y tick marks. (The y data have to be converted to logarithms separately.) 23: same as 3 except logarithmic y tick marks. (The y data have to be converted to logarithms separately.) 30: same as 0 except logarithmic x and y tick marks. (The x and y data have to be con- verted to logarithms separately.) 31: same as 1 except logarithmic x and y tick marks. (The x and y data have to be converted to logarithms separately.) 32: same as 2 except logarithmic x and y tick marks. (The x and y data have to be converted to logarithms separately.) 33: same as 3 except logarithmic x and y tick marks. (The x and y data have to be converted to logarithms separately.) 40: same as 0 except date / time x labels. 41: same as 1 except date / time x labels. 42: same as 2 except date / time x labels. 43: same as 3 except date / time x labels. 50: same as 0 except date / time y labels. 51: same as 1 except date / time y labels. 52: same as 2 except date / time y labels. 53: same as 3 except date / time y labels. 60: same as 0 except date / time x and y labels. 61: same as 1 except date / time x and y labels. 62: same as 2 except date / time x and y labels. 63: same as 3 except date / time x and y labels. 70: same as 0 except custom x and y labels. 71: same as 1 except custom x and y labels. 72: same as 2 except custom x and y labels. 73: same as 3 except custom x and y labels.
