generate point plots
PointPlot(X, options, plotoptions)
(optional) equation(s) of the form option=value where option is one of color, symbol, format, orientation, scale, or xcoords; specify options for generating the point plot
options to be passed to the plots[display] command
The PointPlot command generates a point plot 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 points 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.
symbol=name or list
This option specifies symbols for the individual data sets. When a list of symbols is given, each of the points is plotted using the corresponding symbol in the list.
format=default or stacked
By default, individual data sets are displayed as independent sets of points. A stacked point plot shows related data groups, one on top of the other. A percent point plot is similar to a stacked point plot, 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.
A ≔ 1,2,3,4,2,3,1:
B ≔ 1,5,1,0,2,1,1:
C ≔ 1,2,1,3,1,4,2:
PointPlot⁡A,B,C,format=stacked,color=Indigo..Magenta,symbol=diamond,asterisk,circle,title=Stacked Point Plot,gridlines=true
PointPlot⁡A,B,C,format=stacked,scale=relative,color=Blue,symbol=circle,title=Percent Stacked Point Plot,gridlines=true
The PointPlot command also accepts a Matrix. The columns are understood as individual data samples.
M ≔ A|B|C
