SET MARKER

        [GREG1\]SET MARKER Nsides Mstyle Size Orien

    Sets the marker type to a polygon of Nsides, of style Mstyle  (0-4)  and
    size Size (physical units).
        Nsides:
          - 0,1 Dots
          - 2 Bar
          - 3 Triangle
          - ...
        Mstyle:
          - 0 Convex polygon
          - 1 Vertex connected
          - 2 Starred polygon
          - 3 Filled convex polygon (only for Nsides>=3)
          - 4 Filled starred polygon (only for Nsides>=3)

    The default is Nsides=0 Mstyle=0 Size=0 and Orientation 0 (Points, opti-
    mized algorithm). The Orientation is used to plot the marker (e.g. Hori-
    zontal bar for MARKER 2 0 * 0.0, and vertical bar for same marker MARKER
    2 0 * 90.0).

    A * instead of a numerical value indicate to keep the last value.
