The graph options are broken into sev eral categories

The graph options
are broken into sev-
eral categories,
appearing on the
left-hand side of the
dialog. Make cer-
tain that you are displaying the Basic type page, then change the specific type to Distribu-
tion . Notice that there is a combo on the right-hand side that offers you choices on which
type of distribution graph to produce. Since we want to display the default histogram, sim-
ply click on OK .

438 —Chapter 13. Graphing Data
The view of the series will change to
show a histogram of the data in the
series.
The histogram is an example of an
analytic graph in which the data are
plotted against a data scale, not the
workfile observation scale; note that
the horizontal axis in the graph no
longer corresponds to dates in the
workfile, but instead represents
intervals of data values observed
from data included in the workfile
sample. In this case, we show bars
whose heights represent frequencies
for the data intervals depicted on the horizontal axis.
Similarly you may display graphs for a group of series by opening the group, selecting
View/Graph... and choosing an appropriate type.
First, open the group object
GROUP01 in the workfile, then
select View/Graph... from the group
menu and click on OK to accept the
defaults. By default, EViews will dis-
play line graphs of the two series
within a single graph frame.
As before, we may change the graph
to a histogram view by double-click-
ing on the graph or selecting View/
Graph... to display the dialog.
Change the specific type to Distribu-
tion and click OK to accept the
default settings.

Graphing a Series— 439
The group view will change to show histograms of the data in the two series. Note that by
default, the histograms are displayed in separate frames (we have rearranged the graphs
horizontally for presentation by right-clicking on the graph and selecting Position and align
graphs... ; see “Working with Multiple Graphs” on page 583 ). Note also that each of the
frames has its own vertical and horizontal axis scale.
Displaying other graph views is generally just as easy. Most graphs can be displayed with a
few mouse clicks and a couple of keystrokes. In general, you can simply open the series or
group object, display the graph dialog, select the graph type, set a few options if necessary,
and click OK to produce acceptable results.
Graphing a Series
Up to this point we have examined graph views for series and groups constructed using
default settings. We now consider the process of displaying graph views of a single series in
a bit more depth.
Our discussion focuses on the selection of a graph type and setting of associated options.
We consider the general features of selecting a graph type for the series, not on the particu-
lars associated with each graph type. Details on the individual graph types are provided in
“Graph Types,” beginning on page 479 .
