#### `plenv0`: Same as `plenv` but if in multiplot mode does not advance the subpage, instead clears it

`plenv0 (` | xmin,
| xmax,
| ymin,
| ymax,
| just,
| axis`)`;

Sets up plotter environment for simple graphs by calling `pladv` and setting up viewport and window to sensible default values. `plenv0` leaves a standard margin (left-hand margin of eight character heights, and a margin around the other three sides of five character heights) around most graphs for axis labels and a title. When these defaults are not suitable, use the individual routines `plvpas`, `plvpor`, or `plvasp` for setting up the viewport, `plwind` for defining the window, and `plbox` for drawing the box.

`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` using `plsvpa`, `plvasp` 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.
