| contour filling | filled | switch on [b] [c] | |||
| Notes: a. Note that these function require input from a sla file. b. Contour filling is currently very, very rudimentary. The The zero level is a baseline and contours are filled downwards to -ive and then upwards to +ive. The upshot is that for re-entrant contour levels the contour will (a) be filled one color in the wrong direction and (b) be overwritten by the nearest local maxima/minima of the reentrant curve portion. You have been warned! c. Contour filling will not be apparent unless PLOTX or PREVUE are invoked with the "color fill" option. | |||||
| LEVELS | Option | Code | Arg | ||
| type of contour [a] | arith | arithmetic intervals | |||
| geom | geometric intervals | ||||
| direct | explicit levels input | ||||
| number of contours [a] [b] | nc | n | number of contours | ||
| starting contour level[b] | start | n | first level | ||

| zincl | include | ||||
| Notes: a. These items are mandatory. b. Codes nc , start , and incr are not allowed for the direct option - follow the direct flag on the input line with the levels desired. The levels line can function in a cumulative manner for the direct option. The negate and zincl operations are not performed until all line input is complete. | |||||

| dashed line [a] | dashed | n m | |||
| dotted lines | dotted | n m | |||
| solid line | solid | n m | |||
| Notes: a. The n is the first line and m the last line to be assigned to this type. Both n and m must be input. The lines are assigned sequentially. Options can be input in any order and in any combination of line types. | |||||

| Notes: a. A maximum of 10 elements is allowed. The lengths are relative to a y-dimension (down the page) of 10 units. | |||
