As illustrated in Chapter 1, you can usethe stretch, compress, and zoom buttons on the command panel.Alternatively, you can specify a particular scale for a view or correlationfunction using the Manual Scaling... command on the Options menu. Forexample, selecting Manual Scaling... while the active pane contains awaveform brings up the Scale Waveform dialog box shown in Figure 8.2.Figure 8.2. The Scale Waveform dialog box.Similar dialog boxes appear for scaling spectrogram and spectrum panes, andfor correlation functions. In all of the manual scaling dialogs, a pop-up unitsmenu lets you choose inches, centimeters, or pixels as the display unit. In eachdialog, you specify the scale for the horizontal and vertical axes by typing inthe number of dimensional units (i.e., seconds, pascals, hertz, decibels,joules/m 2 /Hz, or correlation units) per display unit. Pop-up menus let youchoose a multiple of the basic dimensional unit (e.g., mS, S, µS for time axes).The values that are displayed when the dialog box first appears are the scale atwhich the plot is currently drawn.Checking the Apply to all windows box applies the specified scale to allwindows that contain a pane of the same type as the pane whose scale isdisplayed in the dialog box. This feature is particularly useful for comparingpanes that are initially drawn at different scales (e.g., because the signals areof different durations).Changing the scale of one pane in a signal window always changes the scaleof at least one other pane because the scales of panes are linked by theirCanary 1.2 User’s Manual 125
