The CumulativeSumChart command generates a cumulative sum chart for the specified data. Several formats are available for multiple data sets: default, stacked and percent stacked. See format option below for more information.

The first parameter X is either a single data sample - given as e.g. a Vector - or a list of data samples. Note that the individual samples may be of variable size.

If the ['interactive'] option is used, then a dialog box appears that allows for customized creation of the plot.

The options argument can contain one or more of the options shown below. All unrecognized options will be passed to the plots[display] command. See plot/options for details.

color=name, list, or range

This option specifies colors for the individual data sets. When a list of colors is given, each of the cumulative sums is colored with the corresponding color in the list. If a range of colors is given, the colors are generated by selecting an appropriate number of equally spaced points in the corresponding hue range.

format=default or stacked

By default, individual data sets are displayed side-by-side as 3-D polygons. A stacked cumulative sum chart shows related data groups, one on top of the other. A percent cumulative sum chart is similar to a stacked cumulative sum chart, except that it is rescaled to a height of 1 while preserving proportionality. If scale is set to relative and format is set to stacked then a percent stacked plot is generated.

markers=true or false

This option specifies whether the original data points appear on the plot. The default value is true.

orientation=vertical or horizontal

This option specifies whether the vertical or the horizontal layout is used. The default value is vertical.

scale=absolute or relative

This option controls whether the absolute or relative data scale is used. If scale is set to relative and format is set to default then all data samples are rescaled so that their range belongs to an interval between -1 and 1. If scale is set to relative and format is set to stacked then a percent stacked plot is generated.

xcoords=default or list

This option specifies the x-coordinates of the data points. By default, the x-coordinates of the points are 1, 2, 3, etc.
