The graph-name argument specifies a unique name for the graph.
The graph-type can be any of "line" or "line-stacked", where "line" is default. With "line-stacked" all graphs are put on-top of each-other.
The -from-now flag allows the plot to start from this point in time, otherwise the already collected data in the system-perfmeter is used also.
The window-size may be used to only look at the latest 'n' points in the history. If not specied all points are drawn.
The x argument specifies which of the probes (added to the monitor) should be used for the x-axis values. Note that it is important for this probe to be monotonically increasing if a normal graph with growing x values is to be plotted. All probes in the monitor are added with a mode option (see the add-probe command), and the delta mode is not suitable for the x-axis probes for this reason.
ys argument specifies one, or several, probes for the y-axis.
The annotations argument can be used to add one or several annotations to each dot in the graph. When the user hover over the dot with the mouse pointer the information will be displayed. Each value in the graph will be annotated with the values from the probes given in this argument (using the probes display settings). If several graphs are displayed in the same window (due to multiple 'ys'), these annotations will be displayed for all graphs.
