Û  2D Special

    This menu contains some special 2D
plot types.  These plot types are widely
used by scientists and engineers.  These
are: histogram chart,  step plot, box
plot, hi-lo plot, and smith chart.

Û  Histogram plot

    Histogram plot is a special type of
  vertical bar chart.  It is useful for
  showing the distribution of values of
  a data set.

Û  Step plot

    This command sets up a step plot type
  in a Cartesian coordinate system.  A
  step plot is a variation of the 2D
  scatter/line plot type.

Û  Box plot

    This command sets up a 2D box plot type
  in a Cartesian coordinate system.  A box
  plot is a special plot type that provide
  statistical information about the
  distribution data.  The horizontal lines
  of a box plot mark the minimum point, the
  10th, 25th, 50th, 75th, and 90th
  percentile points, and the maximum point
  of the data.

Û  Hi-Lo plot

    This command sets up 2D hi-lo plot type
  in a Cartesian coordinate system.  A
  hi-lo plot is another special plot type
  that provide additional statistical
  information about the distribution data.
  The horizontal lines of a hi-lo plot mark
  the mean, standard deviation and standard
  error of the data.  The values are in the
  following increasing order: Mean-2*StdDev,
  Mean-2*StdErr, Mean, Mean+2*StdErr,
  Mean+2*StdDev.

Û  Smith chart

    A Smith chart is a specially designed
  curve plot that is often used in
  microwave engineering to show impedance
  characteristics.
