Boolean Scalar
Valid for: Chart
Normally, charts are drawn in color, with different series being drawn in
different colors to distinguish them. Sometimes, however, you may
want the chart to be drawn in monochrome, for example if you are
printing it on a black-and-white printer. The monochrome
property allows this. If you set it to 1, all the elements of the
chart will be drawn in the Chart object's Foreground color (by
default, black).
Since this means that the different series cannot
be distinguished by color, they will instead be distinguished by line
type (solid, dashed, dotted, etc) or by fill pattern (vertical
hatch, horizontal hatch etc). See the linetype
and fillpattern properties
of the Series object for more information on these.
