generate line charts
LineChart(X, options, plotoptions)
(optional) equation(s) of the form option=value where option is one of color, format, orientation, scale, or xcoords; specify options for generating the line chart
options to be passed to the plots[display] command
The LineChart command generates a line 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 lines 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 as separate lines in the same coordinate system. A stacked line chart shows related data groups, one on top of the other. A percent line chart is similar to a stacked line 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.
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.

The LineChart command also accepts a Matrix. The columns are understood as individual data samples.
