plenv: Set up standard window and draw box
Declaration
public void env(Double xmin, Double xmax, Double ymin, Double ymax, AxesScale just, AxisBox axis)Parameters
| Type | Name | Description |
|---|---|---|
| Double | xmin | Value of x at left-hand edge of window (in world coordinates). |
| Double | xmax | Value of x at right-hand edge of window (in world coordinates). |
| Double | ymin | Value of y at bottom edge of window (in world coordinates). |
| Double | ymax | Value of y at top edge of window (in world coordinates). |
| AxesScale | just | Controls how the axes will be scaled: -1: the scales will not be set, the user must set up the scale before calling plenv 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. |
| AxisBox | axis | 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. |
Remarks
Sets up plotter environment for simple graphs by calling pladv and setting up viewport and window to sensible default values. plenv 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.
