In the Graph Plots view, the graph plot modifiers in the toolbar control the type of output for the active channel(s).

The graph plot modifiers enable you to:

Note that some options are only available when you select Show advanced . This is noted in their descriptions.

Note
In a similar way to selecting different Channel Types with an Active Channel, graph plot modifiers will:

  • Add an additional set of subplots according to the last selected graph plot modifier (if applicable) if the channel is pinned
  • Change the graph type according to the last selected graph plot modifier (if applicable) if the channel is not pinned.

Plot derivatives

To choose whether to plot normal channel data (No Derivative) or a derivative (Velocity or Acceleration) for the selected channel(s), on the Graph Plots toolbar, click the Derivative order dropdown menu.

Change the rotation type


To change the rotation type, on the Graph Plots toolbar, from the Rotation format list, select the required display:
  • Helical format. Axis-angle representation comprising a unit vector that indicates the axis of the rotation, scaled by the angle describing the magnitude of the rotation about the axis.
  • Euler format. Representation composed of 3 rotations about the axes of a coordinate system in a particular sequence.
    The Tait-Bryan set of Euler angle conventions are supported.

This is an advanced graph plot modifier.

Plot channel magnitude

To plot channel magnitude for the active channel(s), on the Graph Plots toolbar, select the Channel magnitude button.
Depending on the current selection, when Channel magnitude is activated, the relevant magnitude is displayed.

For more information on how the magnitude may affect an active channel, see Graph Plots reference.

Change the units

To change the units for the active channel(s), on the Graph Plots toolbar, select the Change selected channel units button. Choose from the following options:
  • Angle Choose between degrees (°) or radians (rad).
  • Length Choose between millimeters (mm), centimeters (cm) or meters (m).

Note that the units for each component is displayed with its label along the y-axis.

This is an advanced graph plot modifier.
