7.9.1 Moving an
The FFT/Histogram screen can be moved by dragging the title bar. You can
resize an FFT/Histogram screen as desired by dragging the window corners.
You can also maximize, restore, and minimize the screen using the standard
buttons in the upper-right corner of the window, or by clicking on the
window’s icon in the upper-left corner. When minimized, the FFT/Histogram
screen shows as an icon on the task bar. Use the close button (red X) to finish
using an FFT/Histogram screen. There is also a help button (? : the question-
mark button) that brings up online help about the FFT/Histogram window.

7.9.2 Displaying FFT Spectra or Histograms
To display an FFT spectrum or histogram you must make these selections: a
table, a row item, and a display type. First, use the Select Table drop-down
box to choose a table containing an FFT or Histogram output structure. Only
tables with FFT or Histogram outputs will be listed. Second, use the Select
Data drop-down box to choose the output item from that table (some CRBasic
Programs are written with more than one FFT or Histogram output instruction
in the same table, in which case multiple items will show on this list). Third,

select the type of display method to use with the Graph Type drop-down box
(Area, Histogram, Bar, Line, Fast Line, Volume). With these three items
properly selected, you can press the Start button to begin monitoring the FFT
spectra or histogram
The y-axis scale shows on the left side of the graphical area, and the x-axis
scale is shown at the bottom of the graphical display area.
