Controls for canonical wheel diagrams

Show node shadings for canonical quantities

The wheel  control is used to switch node shadings on influence diagrams from standard to canonical quantities. The control only has any effect when the influence  option has been selected. See §11.7 for further details.  

Set small effect shading size
 


tex2html_wrap_inline33790 tex2html_wrap_inline33790 Usage

  • BD>control  spokeshade =R tex2html_wrap_inline33712 where tex2html_wrap_inline42410 is a real number.

  • the default is tex2html_wrap_inline42512 .

The spokeshade  control is used to control the amonut of shading produced by a given canonical quantity diagnostic. Full inner shading corresponds to any size ratio not less than the threshhold of R. Inner shading for spokes with size ratios smaller than R have shading in proportion, so that a size ratio of 2.0 will result in one quarter shading of the inner node when the default of R=8.0 is used. The setting of the spokeshade  control is relevant only when the wheel  control is switched on. See §11.7 for further details.  

Set number of spokes
 


tex2html_wrap_inline33790 tex2html_wrap_inline33790 Usage

  • BD>control  spokes =I tex2html_wrap_inline33712 where tex2html_wrap_inline42554 is an integer.

  • the default is tex2html_wrap_inline33914 , meaning all.

The spokes  control is used to set the number of spokes for a canonical wheel. Suppose that an adjustment is carried out for which there are r canonical quantities. Diagnostic shading for node B can therefore be for up to r canonical quantities, with one ``spoke'' for each canonical quantity. The default value I=0, which means all, will produce node shadings for all r canonical quantities. Alternatively, if you wish to see shadings for the first q<r canonical directions only, issue the control with I=q. This will then produce node shadings for q+1 spokes, with the extra shading in the final spoke aggregating the diagnostic information for the last q-r canonical directions. This is relevant only when the wheel  control is switched on. See §11.7 for further details.  

Setting spoke shade colours
 


tex2html_wrap_inline33790 tex2html_wrap_inline33790 Usage

  • BD>control  spokecolour =I tex2html_wrap_inline33712 where tex2html_wrap_inline42438 is an integer.

  • the default is tex2html_wrap_inline42516 .

tex2html_wrap_inline33806 tex2html_wrap_inline33806

The spokecolour  control is used to set the colour used for shading inner node areas representing diagnostics for canonical quantities for nodes which have been subject to a previous adjustment. This is relevant only when the wheel  control is switched on. Table 11.3 contains a list of available colours. See §11.7 for further details.
