box¶

Purpose¶

Graphs data using the box graph percentile method.

Note

This function uses the deprecated PQG graphics. Use plotBox() instead.

pgraph

Format¶

box(grp, y)
Parameters
• grp (1xM vector) – This contains the group numbers corresponding to each column of y data. If scalar 0, a sequence from 1 to cols(y) will be generated automatically for the x-axis.

• y (NxM matrix) – Each column represents the set of y values for an individual percentiles box symbol.

Global Input¶

_pboxctl

5x1 vector, controls box style, width, and color.

 [1] box width between 0 and 1. If zero, the box plot is drawn as two vertical lines representing the quartile ranges with a filled circle representing the 50th percentile. [2] box color. If this is set to 0, the colors may be individually controlled using the global variable _pcolor. [3] Min/max style for the box symbol. One of the following 1 Minimum and maximum taken from the actual limits of the data. Elements 4 and 5 are ignored. 2 Statistical standard with the minimum and maximum calculated according to interquartile range as follows: intqrange = 75th - 25th min = 25th - 1.5 intqrange max = 75th + 1.5 intqrange Elements 4 and 5 are ignored. 3 Minimum and maximum percentiles taken from elements 4 and 5. [4] Minimum percentile value (0-100) if _pboxctl[3] = 3. [5] Maximum percentile value (0-100) if _pboxctl[3] = 3.
_plctrl

1xM vector or scalar as follows:

 0 Plot boxes only, no symbols. 1 Plot boxes and plot symbols which lie outside the min and max box values. 2 Plot boxes and all symbols. -1 Plot symbols only, no boxes.

These capabilities are in addition to the usual line control capabilities of _plctrl.

_pcolor

1xM vector or scalar for symbol colors. If scalar, all symbols will be one color.

Remarks¶

If missing values are encountered in the y data, they will be ignored
