Or, if you're willing to bring in the "big guns", R can do radar plots, and you can call R from Perl. The following example creates "chart.png" as a radar-plot. It requires R, the "fmsb" R library and the Statistics::R perl module. ==== #!/usr/bin/env perl use strict; use warnings; use Statistics::R; my $output_file = "chart.png"; ## Contrived example of passing Perl values to the R script my @total_values = ( 2.2, 3.3, 4.1 ); my @phys_values = ( 1, 7, 14 ) ; my @psycho_values = ( 2,2,2.8 ); my $R_script=<<"EOF"; # Radarchart example loosely based on # http://www.inside-r.org/packages/cran/fmsb/docs/radarchart # Prepare Min/Max values maxmin = data.frame( total=c(5,1), phys=c(15,3), psycho=c(3,0) ) # assume "total_values","phys_values","psycho_values" # are existing R vector variables (will be created by Perl before running this script) dat = data.frame( total = total_values, phys = phys_values, psycho= psycho_values ); dat = rbind(maxmin,dat) library(fmsb) png(filename="$output_file",width=800,height=600,units="px") radarchart(dat,axistype=1,seg=3,plty=1,title="Perl/R RadarChart Example") dummy=dev.off() EOF # Create the R object my $R = Statistics::R->new( shared => 1 ); # Create R vector variables with the data values $R->set("total_values", \@total_values); $R->set("phys_values", \@phys_values); $R->set("psycho_values", \@psycho_values); # Run the script $R->run($R_script); ==== -gordon _______________________________________________ Perl mailing list [email protected] http://mail.perl.org.il/mailman/listinfo/perl
