This network plots a histogram of the data values in a data set (strictly speaking in a DX field; see Section 17). It also displays the median, minimum and maximum values in the data. It will work on -dimensional gridded data and -dimensional particle data. It can be used for preliminary investigation of a dataset about which you have no prior knowledge, in order to determine the range and distribution of values which it contains.
The network is shown in Figure 10.
The histogram is generated by module ‘Histogram’ and turned into a graph by module ‘Plot’. The minimum and maximum values in the data are calculated by ‘Statistics’. ‘Format’ and ‘Caption’ assemble the median, minimum and maximum into a text string and ‘Collect’ combines the string with the graph.
If your data are in Starlink NDF format then an alternative way to generate a histogram
is to use command
HIST in Figaro (see SUN/86). This option will work for
