In this case @var{x} can either be a vector, ## the same length as the number of rows in @var{y}, or it can be a ## matrix of the same size as @var{y}. ## ## The default color is @qcode{"b"} (blue), the default line style is ## @qcode{"-"}, and the default marker is @qcode{"o"}. The line style can ## be altered by the @code{linespec} argument in the same manner as the ## @code{plot} command. If the @qcode{"filled"} argument is present the ## markers at the top of the stems will be filled in. For example, ## ## @example ## @group ## x = 1:10; ## y = 2*x; ## stem (x, y, "r"); ## @end group ## @end example ## ## @noindent ## plots 10 stems with heights from 2 to 20 in red; ## ## Optional property/value pairs may be specified to control the appearance ## of the plot. ## ## If the first argument @var{hax} is an axes handle, then plot into this axis, ## rather than the current axes returned by @code{gca}. ## ## The optional return value @var{h} is a handle to a @nospell{"stem series"} ## hggroup. The single hggroup handle has all of the graphical elements ## comprising the plot as its children; This allows the properties of ## multiple graphics objects to be changed by modifying just a single ## property of the @nospell{"stem series"} hggroup. ## ## For example, ## ## @example ## @group ## x = [0:10]'; ## y = [sin(x), cos(x)] ## h = stem (x, y); ## set (h(2), "color", "g"); ## set (h(1), "basevalue", -1) ## @end group ## @end example ## ## @noindent ## changes the color of the second @nospell{"stem series"} and moves the base ## line of the first. ## ## Stem Series Properties ## ## @table @asis ## @item linestyle ## The linestyle of the stem. (Default: @qcode{"-"}) ## ## @item linewidth ## The width of the stem. (Default: 0.5) ## ## @item color ## The color of the stem, and if not separately specified, the marker. ## (Default: @qcode{"b"} [blue]) ## ## @item marker ## The marker symbol to use at the top of each stem. (Default: @qcode{"o"}) ## ## @item markeredgecolor ## The edge color of the marker. (Default: @qcode{"color"} property) ## ## @item markerfacecolor ## The color to use for @nospell{"filling"} the marker. ## (Default: @qcode{"none"} [unfilled]) ## ## @item markersize ## The size of the marker. (Default: 6) ## ## @item baseline ## The handle of the line object which implements the baseline. Use @code{set} ## with the returned handle to change graphic properties of the baseline. ## ## @item basevalue ## The y-value where the baseline is drawn.
