Graph—161
Graph
Graph object. Specialized object used to hold graphical output.
Graph Declaration
freeze |
...................freeze graphical view of object (p. 303). |
graph.................... |
create graph object using graph command or by merging existing |
|
graphs (p. 316). |
Graphs may be created by declaring a graph using one of the graph commands described below, or by freezing the graphical view of an object. For example:
graph myline.line ser1
graph myscat.scat ser1 ser2
graph myxy.xyline grp1
declare and create the graph objects MYLINE, MYSCAT and MYXY. Alternatively, you can use the freeze command to create graph objects:
freeze(myline) ser1.line
group grp2 ser1 ser2
freeze(myscat) grp2.scat
freeze(myxy) grp1.xyline
which are equivalent to the declarations above.

Graph Examples |
|
You can declare your graph:
graph abc.xyline(m) unemp gnp inf
graph bargraph.bar(d,l)unemp gnp
Alternately, you may freeze any graphical view:
freeze(mykernel) ser1.kdensity
You can change the graph type,
graph mygraph.line ser1
mygraph.hist
or combine multiple graphs:
Group—163
graph xyz.merge graph1 graph2
Group
Group of series. Groups are used for working with collections of series objects (series, alphas, links).
