Documentation

Class interfacing to the plotmtv program. Can do 2-d or simple 3-d plots. Arguments take typically either Vector or Matrix instances. Relies on 'system' command to launch plotmtv program (thus only runs on UNIX-like OS).

plotmtv(int id=0)

Constructor. Takes care of opening the file.

Parameters:

id - if set to zero, a radom file name will be generated. Otherwise the filename will bear the name "table<id>.mtv".

~plotmtv()

Destructor. Close file.

void plot(const Vec &x, const Vec &y, std::string line="b|", std::string marker="ro")

2-D plot.

Colours can be k (black), y (yellow), c (cyan), g (green), r (red), b (blue), m (magenta), p (pink), s (steelblue), n (brown). Lines can be ' ' (none), | (solid), l (dashed), ! (dotted-dashed), : (dotted) Markers can be ' ' (none), . (dots), +, x, s (squares), l (lozenges), \^ (up-triangles), v (down-triangles), o

Parameters:

- x abscissae
- y ordinates
line - line colour/type. Examples are "r:" (red dotted), "b|" (blue solid), "gI" (green dotted)
marker - marker colour/type. Examples are "ro", "bx", "g."

void plot(const Mat &z, const double xrange[2]=plotmtv_ZERO_ONE, const double yrange[2]=plotmtv_ZERO_ONE, const double zrange[2]=plotmtv_ZERO_ONE)

3-D plot on regular/uniform mesh.

Parameters:

z - elevation
xrange - min/max along x (default is {0., 1.})
yrange - min/max along y (default is {0., 1.})
zrange - min/max along z (default is {0., 1.})

void plot(const Vec &x, const Vec &y, const Vec &z)

3-D plot on non-uniform, rectilinear mesh.

Parameters:

- x coordinates
- y coordinates
z - elevation

void plot(const Mat &x, const Mat &y, const Mat &z)

3-D plot on general, irregular mesh.

Parameters:

- x coordinates
- y coordinates
z - elevation
