4.7    Scale

The 2D/3D Fields Distribution window enables the following scaling for displayed components values, in both, 2D and 3D displays:

 

Linear scale can be set using button_2dsurface_scale2_linear command under button_2dsurface_scale button in 2D Surface tab, under button_thermal_scale button in 2D Thermal tab, under button_vector_scale button in 3D Vector tab, and under button_viewer_scale button in 3D Viewer tab or Scale->Linear command from main menu, context menu or display dedicated colour bar context menu.

Decibel scale can be set using button_2dsurface_scale2_decibel command under button_2dsurface_scale button in 2D Surface tab, under button_thermal_scale button in 2D Thermal tab, under button_vector_scale button in 3D Vector tab, and under button_viewer_scale button in 3D Viewer tab or Scale->Decibel command from main menu, context menu or display dedicated colour bar context menu. Values Vlog in the Decibel scale are calculated from values Vlin in the linear scale as: Vlog=K*log(Vlin/L), where L=1 in the units of Vlin, and K=20/10 for field/power quantities.

 

The button_2dsurface_scale2_setscale command under button_2dsurface_scale button in 2D Surface tab, under button_vector_scale button in 3D Vector tab, and under button_viewer_scale button in 3D Viewer tab or Scale->Set Scale… command from main menu, context menu or display dedicated colour bar context menu, invoke Set Scale dialogue for setting scale parameters for Lines Art, Lines Art Filled, 3D Vector and 3D Viewer displays.

The button_thermal_scale2_manual command under button_thermal_scale button in 2D Thermal tab or Type->Thermal->Scale->Manual… command from main menu, context menu or display dedicated colour bar context menu invoke Scaling dialogue for setting scale parameters for Thermal displays.

The button_thermal_scale2_fullauto command under button_thermal_scale button in 2D Thermal tab or Type->Thermal->Scale->Full Auto command from main menu, context menu or display dedicated colour bar context menu set scale to automatic for Thermal displays.

The button_thermal_scale2_expandonly command under button_thermal_scale button in 2D Thermal tab or Type->Thermal->Scale->Expand Only command from main menu, context menu or display dedicated colour bar context menu set expand scale mode for Thermal displays. The scale extends to distinguish the increasing (positive or negative) fields but it does not shrink.

 

The button_2dsurface_scale2_showunit command under button_2dsurface_scale button in 2D Surface tab, under button_thermal_scale button in 2D Thermal tab, under button_vector_scale button in 3D Vector tab, and under button_viewer_scale button in 3D Viewer tab or Scale->Show Unit command from main menu, context menu, and display dedicated colour bar context menu, or Show Unit from unit/values context menu show or hide the units and formula that are shown at the top of the colour bar.

The button_2dsurface_scale2_showvalues command under button_2dsurface_scale button in 2D Surface tab, under button_thermal_scale button in 2D Thermal tab, under button_vector_scale button in 3D Vector tab, and under button_viewer_scale button in 3D Viewer tab or Scale->Show Values command from main menu, context menu, and display dedicated colour bar context menu, or Show Values from unit/values context menu show or hide the minimum and maximum values of the colour scale that are shown at the top and bottom of the colour bar.

The button_2dsurface_scale2_setfont command under button_2dsurface_scale button in 2D Surface tab, under button_thermal_scale button in 2D Thermal tab, under button_vector_scale button in 3D Vector tab, and under button_viewer_scale button in 3D Viewer tab or Scale->Set Font… command from main menu, context menu or display dedicated colour bar context menu open Select Font dialogue for choosing the font for units and formula and the minimum and maximum values of the colour scale that are shown at the top and bottom of the colour bar.

 

The button_display_auto button in Display tab or Type->Surface->Display Switch->Frozen Scale off command from main menu, context menu or display dedicated colour bar context menu switches frozen scale on or off (Auto). In this mode the scale covered by the colour palette dynamically adjusts to the current range of the displayed field. An indication of this mode are flickering maximum and minimum field values assigned to the bottom and top of the colour bar. In some cases, the user may wish to freeze the current scale and have the shrinking or increasing field values automatically reflected in the changing range of colours used in the display.
