The number of output raster maps is determined by the number of "bins" specified by the user using the parameters input1 and input2. The users gives the range and density of bins with input1=Start1,End1,Nbins1 input2=Start2,End2,Nbins2. In this case the data from the first data set will be assigned to Nbins1 intervals between Start1 and End1 and Nbins2 intervals between Start2 and End2 for the second data set. In addition, r.jpdf will calculate extra bins for values below or above the start and end values given by the user. In total, the output will consist of (Nbins1+2)×(Nbins2+2) raster maps. The naming of the output rasters is Prefix_N1_N2 where Prefix is given by the parameter output. N1 and N2 may contain leading zeros.
r.series input1="`g.list pattern='temperature*' sep=,`" input2="`g.list pattern='pressure*' sep=,`"\ output=jpdf_temp_pres bins1=-20,40,10 bins2=950,1030,10
Note the g.list script also supports regular expressions for selecting map names.
