9.5.3.1 The (Plot Details) 3D Vector Tab

Starting with Origin 8.5, 3D vector plots can be created from XYZ XYZ data that specifies the start point and the end point of a vector. Alternately, you can create a 3D vector from XYZ dXdYdZ data, which plots the vector dXdYdZ from the starting point XYZ. After you create a 3D vector graph, you can easily do the following things within the 3D Vector tab below:

Specify the color of the vectors using another data set
Rescale all the vectors to avoid overlap
Set the arrow head size according to the magnitude of the vectors

6 End Point Group

Enable 3D Vector

Specify whether to enable 3D Vectors. If you have created a 3D Vector graph from the toolbar or main menu, the check box will be automatically enabled.

Color

Select a vector color from the Color button.

Style

Choose Solid (default) or one of the dash/dot line styles.

Width

Type or select the desired vector width in the Width combination box. Units are measured in points.

Arrowheads group controls

Scale Length with Magnitude	Scale the lengths of the arrowheads according to changes in magnitude of the vectors. Available options include: None All the arrowheads share the same length, specified by Length. Log The lengths of the arrowheads have a logarithmic relationship with the lengths of the vectors. Linear The lengths of the arrowheads have a linear relationship with the lengths of the vectors.
Length	Determines the length of the arrowheads. Units are measured in points.
Angle	Determines the arrowhead angles in degrees.
Closed/Open	Select the Closed radio button to display filled arrowheads. Select the Open radio button to display hollow (transparent) arrowheads.

End Point Group

Vector Type	Specify whether to create an XYZ XYZ 3D vector or an XYZ dXdYdZ 3D vector.
XEnd	This is only available when XYZ XYZ has been selected in the Vector Type drop-down list. It allows you to select the column that contains the X end point values from the X End drop-down list.
YEnd	This is only available when XYZ XYZ has been selected in the Vector Type drop-down list. It allows you to select the column that contains the Y end point values from the Y End drop-down list.
ZEnd	This is only available when XYZ XYZ has been selected in the Vector Type drop-down list. It allows you to select the column that contains the Z end point values from the Z End drop-down list.
dX	This is only available when XYZ dXdYdZ has been selected in the Vector Type drop-down list. It allows you to select the X component of the dXdYdZ vector.
dY	This is only available when XYZ dXdYdZ has been selected in the Vector Type drop-down list. It allows you to select the Y component of the dXdYdZ vector.
dZ	This is only available when XYZ dXdYdZ has been selected in the Vector Type drop-down list. It allows you to select the Z component of the dXdYdZ vector.
Scaling Factor	Select or type a value by which to scale the length of the vectors. For example, type .5 to draw the vectors at half their original lengths.
