General Plot Menu Items

Plot management

A curve can be toggled on/off by clicking in the corresponding data/model icon.
On color screens the curves are color coded along with the data/model.
By pointing at a curve and clicking (shift-click or right mouse button if Zoom is enabled) the curve can also be identified.
For multi-input multi-output data/models the input-output pair is chosen by the menu item Channel.

File Menu in Plot Windows

Copy figure
  Copies the plot to a new MATLAB figure, but does not copy menus and controls.
Print
  Opens MATLAB's Print Dialog for the current figure.
Close
  Closes the current window. This is equivalent to unchecking associated ident View check box. It is the preferred way of closing the figure. Quitting by the window manager title bar will not provide feedback to the identification software.

Style Menu in Plot Windows

Grid
  Toggles gridding.
Zoom
  Toggles zoom.
  When the Zoom function is enabled, the left and middle buttons have their normal MATLAB ZOOM function: Middle: Zoom out. Left: Zoom in. The right button has a plot specific identification function. Typically, clicking the right button associates a line with its data set or model. Other functionality will be related via a status line. When the Zoom function is disabled, all mouse buttons perform the right button function.

  If the zoom malfunctions after a data change in the plot, invoke Autorange under the Options menu to reset it.

Separate linestyles
All solid lines
  These mutually exclusive checkmenus determine how the curves are plotted. On black and white monitors, using the Separate linestyle option will help associate the curves with the right data/model.

  When this menu item is chosen the currently visible curves will be assigned solid, dashed, dotted and dash-dotted linestyles.

Erasemode xor
Erasemode normal
  These mutually exclusive checkmenus determine how the curves are plotted. Erasemode xor means that the plot is not redrawn when a curve is clicked in and out. This gives a faster response, but may give bad quality on certain color screens. Erasemode normal means that the entire plot will be redrawn when a new curve is added or deleted.

Channel Menu in Plot Windows The selected checkmenu under the Channel menu relates which input-output relation is plotted.

For example u1->y2 means that the relationship between input number 1 and output number 2 is displayed. The symbol e - as in e3->y1 - refers to a noise source. There are as many noise sources as outputs.

For the Model output and Noise spectrum Views, only the output number matters.

The current channel number is always displayed in the figure title.

The numbering of the signals remains consistent among different data sets that have been created from an original set.
