Format Menu

This menu is also displayed when you right-click in the graphics area.

Format | Rows Columns

Displays M#s in a Row & Column format.  When it is executed, a matrix of (row, column) format selections is displayed, as shown below.

M#s in Row/Column Format.

Format | Strip Chart

Displays up to 10 M#s together with a common X-Axis below them.

Strip Chart Showing Three M#s.

Format | Overlaid

Displays all (or selected) M#s in overlaid format.

The Y-Axis scaling is changed to Relative when this command is executed. (See Format | Y-Axis for details).

Imaginary Parts of FRFs in Overlaid Format.

Format | Overlay By DOF

If checked, all (or selected) M#s with the same Roving DOF are displayed together in Overlaid format. This command is useful for displaying FRFs & Coherences together in overlaid format.

FRFs & Coherence Overlaid by DOF.

Format | Cascade

Displays all (or selected) M#s in a Cascade plot.  

Cascade Plot.

Format | Contour Map

Displays all (or selected) M#s in a color contour map.

The colors used for the contour map are chosen in the Contour Colors tab in the File | Data Block Options dialog box.

Cascade Map Showing 14 Selected M#s.

The vertical axis is labeled using either M#s or DOFs, which are chosen in Scroll Tip section on the Labels & Grids tab in the File | Data Block Options box.

Format | Y-Axis

Opens the Y-Axis format dialog box, which is used for formatting the Y-axis of the graphics display.  This dialog box can also be opened by,

  1. Right clicking in the graphics area, and executing Format | Y-Axis from the menu.

  2. Or double clicking on the Y-Axis area of the graphics display.

Scaling

Fixed scaling limits can be defined for the following display formats,

Scaling from the M#s Spreadsheet

Each M# can be scaled by editing its cells in the Y-axis Scale, Fixed Minimum & Fixed Maximum columns of the M#s spreadsheet.

If Fixed scaling is chosen, the Fixed Minimum & Fixed Maximum limits must be entered into their respective columns in the M#s spreadsheet.

dB Units for Linear versus Power Quantities

Magnitudes can be displayed in dB (decibels) units.  For Linear (RMS) quantities, (such as FRFs, Fourier Spectra, etc.) the Magnitude is displayed as,

 

Magnitude (dB) = 20 Log 10( Magnitude )

For Power (MS) quantities (such as Auto & Cross Spectra), the Magnitude is displayed as,

 

Magnitude (dB) = 10 Log 10( Magnitude )

Labels & Grids

Same as the choices on the Labels & Grids tab in the File | Data Block Options box.

Format | X-Axis

Opens the X-Axis dialog box which is used for formatting the X-axis of the graphics display. This dialog box can also be opened by,

  1. Right clicking in the graphics area, and executing Format | X-Axis from the menu.

  2. Or double clicking on the X-Axis in the graphics area

Display Limits

The Starting & Ending limits of the X-Axis display.

X-Axis Label & Axis Units

These two drop down lists define the X-Axis for all M#s in a Data Block.

Labels & Grids

Same as the choices on the Labels & Grids tab in the File | Data Block Options box.
