438—Chapter 13. Graphing DataThe view of the series will change toshow a histogram of the data in theseries.The histogram is an example of ananalytic graph in which the data areplotted against a data scale, not theworkfile observation scale; note thatthe horizontal axis in the graph nolonger corresponds to dates in theworkfile, but instead representsintervals of data values observedfrom data included in the workfilesample. In this case, we show barswhose heights represent frequenciesfor the data intervals depicted on the horizontal axis.Similarly you may display graphs for a group of series by opening the group, selectingView/Graph...and choosing an appropriate type.First, open the group objectGROUP01 in the workfile, thenselectView/Graph...from the groupmenu and click onOKto accept thedefaults. By default, EViews will dis-play line graphs of the two serieswithin a single graph frame.As before, we may change the graphto a histogram view by double-click-ing on the graph or selectingView/Graph...to display the dialog.Change the specific type toDistribu-tionand clickOKto accept thedefault settings.
