play options
8. Use the Histogram to turn on and off the display of the
selected histogram (histogram counting remains
enabled). Use the color list to select a color for the
histogram. Select a value in the Size box to adjust the
histogram display on screen.
9. Select Linear to display histogram data linearly. Bin
counts are scaled linearly by dividing the bin count by
the maximum bin count.
10. Select Logarithmic to display histogram data logarithmi-
cally. Bin counts are scaled logarithmically. Logarithmic
scaling provides better visual details for bins with low
counts.

11. Use the Top, Bottom, Left, and Right boxes to set the
size and location of the histogram box. The histogram
box selects the section of the waveform used for
histograms.
12. Select Absolute to use units based on the source
waveform. Select % to display the histogram box as a
percentage of the graticule. This display setting
considers the top-left corner of the graticule to be 0,0
and the bottom-right corner to be 100,100.
Tip. It is quicker to use the mouse or touchscreen to
drag to size the histogram box on screen, then fine tune
the values if needed with the Limit Controls.
