The Defaults Settings Window
- Window title:
- Defaults Settings
- Function:
- This window displays the current default
ranges for variables, parameters and functions. It also
allows the user to turn on and off data clipping and the
recording of data. Certain global values (used in dstool's numerical or display
algorithms) can be set via this window.
- Description:
- The Defaults Settings Window is opened by selecting the
Defaults option from the Settings menu button located on the
Command Window. If the record data is off then no data is stored.
When record data is on then, if clipping is off, all produced
data is stored. When data clipping is on, only data which
is displayed in at least one view window (iconized or not)
is stored. (This button does nothing if recording data is off.)
The other text fields are the default viewing ranges for
displaying data.
- Panel items:
-
- Coordinate System stack setting: Allows the user to
select a coordinate system. This item is only active
when more than one coordinate system has been defined.
Presently the only choices are Cartesian and Polar.
- Record Data exclusive setting: Allows the
user to turn data recording on and off. The default is on.
- Clip Data exclusive setting: Allows the
user to turn data clipping on and off. The default is off. This setting is
inactive if Record Data is turned off.
- Window Precision numeric field: Allows the user to display from
0 to 17 digits of precision in window text fields. The
default value is 6. The value of this field determines the precision of
the number of decimal places displayed in the dstool window text entries.
- Display Points read-write text field:
During calculations of orbits, dstool
will calculate n points of the orbit before sending the data to be plotted
and stored in memory. The integer n is determined by the value in this
field. The default is 100.
- Diverging read-write text field: During calculations of orbits, dstool
will stop calculations if orbits appear to diverge to infinity.
If the distance from a point to the origin is greater than the number
appearing in this field, then the orbit containing that point is deemed to
have diverged. The default value is 108.
- Plotting Symbol stack setting:
Trajectories are plotted in the symbol determined
by this setting. The default is to plot a dot for each point of a trajectory.
It is also possible to choose to plot with a cross, a triangle, and a box.
- Size stack setting:
Trajectory symbols come in four sizes: small, medium, large, and
huge. The default size is medium.
- Name Min read-write text field: Shows and allows the user
to adjust the default minimum value for viewing this
variable, parameter, or function.
- Name Max read-write text field: Shows and allows the user
to adjust the default high value for viewing this
variable, parameter, or function.
