Preparing histograms.
val hist :
points:r1 Data.t ->
?color:Color.t ->
?bins:int ->
?binwidth:float ->
?legend:string ->
unit ->
r2 spechist ~points ?color ?bins ?binwidth ?legend creates an histogram out of points.
?color specifies the color of the histogram.?bins specifies the number of bins to be used when constructing the histogram.?binwidth specifies the width of each bin: the bigger, the coarser the histogram.?legend specifies the legend attached to the histogram. If neither the ?bins or ?binwidth parameter is specified, this command will let ?bins default to 20 and will let ?binwidth be automatically computed by Gnuplot.
