Curves
Curves
This option can be used to display the unit information for each curve.
The Curve dropdown displays the unit system of the selected curves. It can also be used to update curves that have an undefined unit system.
The Display dropdown shows the display unit system currently used in T/HIS. Display units can be modified from this dropdown or from the Model panel.
The Factor section indicates the mass, length, and time conversion factors between the selected unit system and the display unit system.
| By default, the unit system for each curve is displayed, but this can be changed to show either the X or Y axis unit using the popup menu. |

Setting the Unit System for a Curve
If the unit system for a curve has not been defined then it will
be displayed as "Undefined" and a popup menu will be available
that can be used to select the correct unit system. If the selected
unit system is different to the unit system currently being used
to display results then the curve values will automatically be converted
to the current display unit system.
If a curve is associated with a model, its units can only be modified from the Models panel and not from the Curves panel. Multiple curves can be selected using the Ctrl or Shift keys. Once selected, the units can be changed via the Selected Curves dropdown or the Curves dropdown located at the top of the panel. Note : Once the unit system for a curve has been defined it can not be changed. |
Setting the Axis Units for a Curve
The X and Y axis units of a curve can be defined or changed at any time. The popup menu contains all of the basic Unit types that T/HIS knows about plus an option to setup a user defined unit. To create a user defined unit for a curve, the unit should be defined in terms of its basic properties. The values for mass, length, time, angle, tempetrature and current should be the powers that are used to describe the unit in terms of it's fundamental dimensions. Some examples of common units defined using this method are shown below.
