PSYM
The symbol used to mark each data point. Normally,
PSYM is 0, data points are connected by lines, and no symbols are drawn to
mark the points.
For the web page entry, use IDL array syntax. E.g., for 4 signals, two using diamonds, and two using triagles:
[4,4,5,5]

mode. Horizontal and vertical lines connect the plotted points, as oppose=

the normal method of connecting points with straight lines. |
Negative values of PSYM cause the symbol designated by PSYM to be plotted
at each point with solid lines connecting the symbols. For example, a value
of
-5 plots triangles at each data point and connects the points with lines.
To connect symbols with lines, you could use something like -1*[1,2,3,4].
