\title{A marker on a chart series}
\usage{
xl_chart_marker(type = NULL, size = NA, format = NULL)
}
\arguments{
\item{type}{The symbol: `"automatic"`, `"none"`, `"square"`, `"diamond"`,
`"triangle"`, `"x"`, `"star"`, `"short_dash"`, `"long_dash"`, `"circle"`
or `"plus"`.}

\item{size}{The symbol's size in points, 2 to 72.}

\item{format}{An [xl_format()] styling the symbol: [xl_border()] for its
outline, [xl_fill()] for its fill or pattern.}
}
\value{
An `xl_chart_marker` object.
}
\description{
`xl_chart_marker()` draws a symbol at each point of a series.  Line, scatter
and radar charts are where they show; on other types Excel ignores them.

`type = "automatic"` asks Excel for the default marker of that series, and
is the one type that cannot be given a size or a format --- libxlsxwriter
documents that, and Excel drops them, so both are refused here.
