The display and plot options are controlled from the toolbar and from context menus. There is tooltip text on the toolbar buttons that will appear when the mouse pointer hovers over the icon. The context menus are displayed by right-clicking on the appropriate area of the GUI. The features to control the display of the plot axes legend, the listed attributes for the references and responses, and the appearance of the plot axes are described below.
Selecting a plotted line with the mouse pointer and holding down the middle button will highlight that line and its corresponding entry in the plot legend. Selecting a line in the plot legend with the mouse pointer and holding down the middle button will highlight that line and the corresponding line in the plot axes (this feature is not available in Matlab R2014b or later). The associated line in the other plot axes will also be highlighted, if applicable, and the name from the legend will be displayed in the message line at the bottom of the window.
Legend – There is a toggle button on the toolbar to show or hide the plot axes legend.
Legend Info – Select the attributes that are displayed in the legend from the context menus on the References and Responses listboxes on the right side of the GUI. The displayed attributes can be any combination of Coordinate (i.e., node number and direction, e.g., 1001X+), ID Line (ID Line 1 for responses and ID Line 2 for references) and Data Type (ordinate numerator data type for responses and ordinate denominator data type for references). The Legend Info can also be 'as listed', in which case the attributes displayed in legend are the same as listed in References and Responses listboxes.
List by – Select the list and sort attributes for the References and Responses listboxes on the right side of the GUI from their context menus. The List by attributes can be Coordinate (i.e., node number and direction, e.g., 1001X+), Coordinate and Data Type (ordinate numerator data type for responses and ordinate denominator data type for references) or ID Line (ID Line 1 for responses and ID Line 2 for references).
Axes Context Menus – The plot axes have a context menu that contains controls to tailor many aspects of the plot appearance. The plot axes context menu options are described below.
Window |
none |
When selected, axis limits will be controlled by MATLAB. |
tight |
When selected, axis limits will be adjusted to exactly envelope the data plotted. |
|
pick X |
When selected, X limits will be defined by manually picking them from the plot. |
|
pick X, tight Y |
When selected, X limits will be defined by manually picking them from the plot. Y limits will be adjusted to exactly envelope the data plotted. |
|
pick Y |
When selected, Y limits will be defined by manually picking them from the plot. |
|
pick XY |
When selected, both X and Y limits will be defined by manually picking them from the plot. |
|
key in X |
When selected, X limits will be defined by manually typing them into an input dialog. |
|
key in X, tight Y |
When selected, X limits will be defined by manually typing them into an input dialog. Y limits will be adjusted to exactly envelope the data plotted. |
|
key in Y |
When selected, Y limits will be defined by manually typing them into an input dialog. |
X Scale |
default |
When selected, the X axis will be set to its default. |
linear |
When selected, the X axis will be displayed on a linear scale. |
|
log |
When selected, the X axis will be displayed on a logarithmic (base 10) scale. |
Y Scale |
default |
When selected, the Y axis will be set to its default, which varies by the plotted function. |
linear |
When selected, the Y axis will be displayed on a linear scale. |
|
log |
When selected, the Y axis will be displayed on a logarithmic (base 10) scale. |
Y Limits |
default |
When selected, the Y limits will be scaled to its default. |
fixed |
When selected, the Y limits will be fixed at the current value. |
Complex |
default |
When selected, the plot format will be set to its default. |
modulus + phase |
When selected, the plot will be displayed in two axes. The lower axis displays the modulus (magnitude) and the upper axis displays the phase. |
|
real + imaginary |
When selected, the plot will be displayed in two axes. The lower axis displays the imaginary part of the functions and the upper axis displays the real part. |
Grid |
X and Y |
When selected, grid lines will be applied in both the X and Y directions. |
X only |
When selected, grid lines will only be applied in the X direction. |
|
Y only |
When selected, grid lines will only be applied in the Y direction. |
|
none |
When selected, no grid lines will be applied to the plot. |
Cursor |
add cursor |
Adds an x-cursor to the axes. |
remove all |
Removes all user-added x-cursors from the axes. |
|
phase 90 | Adds a cursor at the 90° phase crossing of the plotted function. |
The x-cursors added to the plot axes have a context menu from which to change the color, marker symbol and fill, and line type of the cursor; make a copy of the cursor; or delete the cursor. The Go To menu selection will open an input dialog to enter the x-value of the cursor. The Make Default menu selection sets the default cursors properties from this cursor. Cursors added subsequently will have these default properties. Added cursors are created at the mouse pointer. For the 90° phase crossing cursor, the line is red and the marker is a red-outlined square. This cursor can be added when only one function is plotted and there is only one 90° phase crossing in the selected frequency range.
Pan |
Toggles the axes panning mode on and off. |
There is also a Pan toggle button on the toolbar. When in pan mode, the axes context menu is replaced by the pan context menu. Cursors cannot be added, deleted, or moved while pan mode is active.
There is a context menu on the upper axes "Phase (deg)" y-label that contains a selection for the "clean phase" option. If "clean phase" is enabled, points where the phase differs by more than 270 degrees from the previous point are not displayed. Also on this context menu are selections to shift the phase of the synthesized FRF by ±360˚.
