Describes a line in terms of x, y, and z points. This VI has three 1D array or vector inputs that specify each point in the plot.

Inputs/Outputs
3D graph
—
3D graph accepts the reference to the 3D control.
x vector
—
x vector is a 1D array of data that contains the x coordinates of the curve.
y vector
—
y vector is a 1D array of data that contains the y coordinates of the curve.
error in (no error)
—
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
z vector
—
z vector is a 1D array of data that contains the z coordinates of the line or curve. The x and y vectors shift or skew the set of data in the z vector.
plot number (1)
—
plot number is the index into the list of plots from the properties of the 3D control. Add new plots by right-clicking the control and adjusting the properties. The default is the first plot from the list.
3D graph out
—
3D graph out passes the reference to the 3D control out so that you can use it with other VIs.
error out
—
error out contains error information. This output provides standard error out functionality. |
