Using the Graph Property Window
➣ To adjust the histogram, right-click on the histogram to open the Graph Property
window. The Graph Property window contains three tabs:
❑ Axis Tab
❑ Event Type Tab
❑ General Tab
This section discusses the tabs in the Graph Property window.
Histogram Axis Tab
The Histogram Axis Tab allows to you define the X-Axis.The Histogram Axis Tab is
exactly like the Scattergram Axis Tab with the exception that the Y-Axis is always
Count and cannot be changed. For information about setting the Histogram Axis Tab,
see “Scattergram and Histogram Axis Tab” on page 4-23.
Histogram Event Type Tab
This tab allows you to specify the events that will trigger a spot on the histogram.
The Histogram Event Type Tab is exactly like the Scattergram Event Type Tab. For
information about setting the Histogram Event Type Tab, see “Scattergram and
Histogram Event Type Tab” on page 4-26.
Histogram General Tab
The General tab allows you to set a number of miscellaneous parameters. The
parameters available from this tab are:
❑ Title—Enter a title for this graph. The title appears at the top of the graph.
❑ # of channels displayed—Specify the resolution of the X-axis. You can specify
either 200 or 500 channels. A “channel,” in this instance, is the number of
divisions along the X-axis. The default is 200.
When you specify 500, iCys displays the histogram in wide mode, as follows:
❑ Bin count—Specify the width of each datapoint in the bar graph. By default, the
number of bins is equal to the number of channels, and each datapoint is one pixel
