** Sheet View's Plot Menu Commands
█ Plot menu
This menu contains commands that
creates new graphs. There are several
2D and 3D plot types. Although it is
easy to create and modify plots with
TechPlot, thought and planning are
still required in order to produce a
high quality graph. The first step
is to decide on the most suitable plot
type. Many different plot types can be
used to display the same data set, but
some are more effective than others
under certain circumstances.
█ 2D Curve
This menu contains three 2D curve
related commands: scatter/line, polar,
and error bar. These plot types (2D
rectangular curve, polar curve, error
bar) are the most common methods of
graphical representation. These commands
produce 2D data plots with or without
line connection. If the data set
represents observed data points, then the
plot will be just the data points listed
on the data sheet. If there is a model or
function in connection to the data you
selected, a smooth curve will be produced.
█ XY Lines
This command sets up 2D line and
scatter plot types in a Cartesian
coordinate system.
█ Polar
This command sets up 2D line and
scatter plot type in a Polar
coordinate system.
█ Error Bar
This command sets up 2D error bar
plot type in a Cartesian coordinate
system.
█ 2D Bar chart
This menu contains commands to create
a 2D bar chart. A bar chart plot draws
perpendicular bars from either the x-axis
(vertical bar) or the y-axis (horizontal
bar) to the data point. Group bar charts
are created by adding more than one column
to the plot.
█ Vertical bars
This command displays the Bar Chart
dialog box which lets you set up 2D
vertical bar plot type in a Cartesian
coordinate system.
█ Horizontal bars
This command sets up 2D horizontal
bar plot type in a Cartesian coordinate
system.
█ 2D Special
See TpSht_04.hlp (Index 43).
█ 3D Curve
This menu contains commands that
creates a 3D curve graph. There are
three coordinate system available in
TechPlot: Cartesian (x, y, z),
Spherical (r, Θ, Φ) and Cylindrical
(r, Θ, z).
█ Scatter/XYZ-Line
This command creates a 3D XYZ
scatter/curve graph.
█ Sphere
This command creates a 3D Spherical
scatter/curve graph.
Note, in the spherical coordinate
system, X is the Θ angle, Y is the Φ
angle, and Z is the radius (r). The
graph is drawn in the XYZ Cartesian
coordinate system. The relationship
between the Cartesian system and the
Spherical system is:
X = r cosΘ sinΦ,
Y = r cosΘ cosΦ,
Z = r sinΘ.
█ Cylinder
This command creates a 3D Cylindrical
scatter/curve graph.
Note, in the spherical coordinate
system, X is the radius (r), Y is the
angle (Θ), and Z is the z-axis. The
graph is drawn in the XYZ Cartesian
coordinate system. The relationship
between the Cartesian system and the
Cylindrical system is:
X = r cosΘ,
Y = r sinΘ,
Z = z.
█ Error Bar
This command creates an Error Bar
curve graph in Cartesian coordinate
system.
█ 3D Bar chart
This command creates a 3D bar graph.
█ 3D Surface
This menu contains four commands that
create 3D surfaces.
█ XYZ
This command creates a 3D Cartesian
surface graph.
█ Sphere
This command creates a 3D Spherical
surface graph.
█ Cylinder
This command creates a 3D Cylindrical
surface graph.
█ Block
This command creates a 3D Cartesian
surface graph.
