The probabilities run from 0 to 1. The number of divisions from 0 to 1 is given by the input. The output can be plotted directly with the xyplo program. examples 1.0 0.4 zerox zeroy graph coordinate center x 0 1 zx min max (character, real, real) if zx='x' then set xaxis y 0 1 zy min max (character, real, real) if zy='y' then set yaxis 10 10 1 1 xinterval yinterval number of intervals on axes to plot 4 4 xwidth ywidth width of numbers in characters 1 1 xdecimal ydecimal number of decimal places 3 3 xsize ysize size of axes in inches probability uncertainty, H (bits) a zc 'c' crosshairs, axXyYnN n 2 zxl base if zxl='l' then make x axis log to the given base n 2 zyl base if zyl='l' then make y axis log to the given base ********************************************************************* 1 2 xcolumn ycolumn columns of xyin that determine plot location 0 symbol column the xyin column to read symbols from 0 0 xscolumn yscolumn columns of xyin that determine the symbol size 0 0 0 hue saturation brightness columns for color manipulation ********************************************************************* symbol-to-plot c(circle)bd(dotted box)x+Ifgpr(rectangle) 0 symbol-flag character in xyin that indicates that this symbol 0.05 symbol sizex side in inches on the x axis of the symbol. 0.05 symbol sizey as for the x axis, get size from yscolumn cl 0.05 no connection (example for connection is c- 0.05 for dashed 0.05 inch) n 0.05 linetype size linetype l.-in and size of dashes or dots ********************************************************************* . ********************************************************************* documentation Figure created by this program (with 100 divisions) is used in https://alum.mit.edu/www/toms/ftp/primer.ps see also xyplo.p author Thomas Dana Schneider bugs none known *) (* end module describe.hgraph *) {This manual page was created by makman 1.45}{created by htmlink 1.62}
