Plots
such as bar charts and histograms use graphical elements that have
a fill color. The
Fill check box is checked
by default. If you specify an outline for the plot, then you can uncheck
the
Fill check box.
When the
Fill check box is checked, then you can specify the
fill color and the transparency. Moving the slider to the right makes
the fill color more transparent. (The other part of the plots, such
as its outline, do not change.) The default value for transparency
is obtained from the plot definition.
You can
toggle the plot's outline on and off. If the
Outline check box is checked, then you can specify a color for the outline.
