:: Plot menu's 2D Special commands
█ 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.
█ 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.
█ 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.
█ 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.
█ 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.
█ Smith chart
A Smith chart is a specially designed
curve plot that is often used in
microwave engineering to show impedance
characteristics.
