orbplot - plot an orbit
orbplot in=orbit [parameter=value]
orbplot will plot an orbit. See also snapplot(1NEMO)
, which has
a similar user interface.
The following parameters are recognized
in any order if the keyword is also given:
- in=in-file
- Input file, which
must be an orbit(5NEMO)
. [No default].
- times=time-range
- Only plot the range
of times within time-range, which is of the form "tstart:tend". [default:
all].
- nplot=number
- The stride through the data of the plotted points [default:
1].
- xvar=x-expression
- The value of x-expression is plotted along the X axis.
x-expression is a real-valued C language expression over the real values
x, y, z, vx, vy, vz, phi, t and thge integer value i. See also snapplot(1NEMO)
.
[Default: x]. (not implemented)
- xlabel=x-axis-label
- Label for the X-axis. [default:
expression used for xvar].
- xrange=x-axis-range
- Range of values for the X axis,
specified as a pair of numbers separated by a colon [default: -2.0:2.0].
- yvar=y-expression
- See above. The default is y. (not implemented)
- ylabel=y-axis-label
- See above.
- yrange=y-axis-range
- See above.
- visib=expression
- Determines the visibility
of points. expression is an integer expression in the above variables;
only points with non-zero values are plotted. [default: 1]. (not implemented)
- psize=expression
- Determines the points type and size. [default 0]. (not implemented)
- maxsteps=num-steps
- Maximum number of steps allowed for an orbit. [Default:
5000].
For xvar= and yvar= currently only the simple variables real
values x, y, z, vx, vy, vz are implemented.
