# plenv0.3plplot man page

**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 possible. 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 positions 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 converted 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.
