332—Appendix B. Command Reference
The “mname=” option stores a q × 6 matrix, where q = m + 1 if there are no exogenous variables in the VAR; otherwise q = m + 2 . The first ( q − 1 ) rows contain the information displayed in the table view, following the same order. The saved matrix has an additional row which contains the lag order selected from each column criterion. The first column (corresponding to the log likelihood values) of the last row is always an NA.
Examples
var var1.ls 1 6 lgdp lm1 lcpi
show var1.laglen(12,vname=v1)
The first line declares and estimates a VAR. The second line computes the lag length criteria up to a maximum of 12 lags and stores the selected lag orders in a vector named V1.

Graph Proc |

Set legend appearance and placement in graphs.
When legend is used with a multiple graph, the legend settings apply to all graphs. See setelem (p. 449) for setting legends for individual graphs in a multiple graph.
Syntax
Graph Proc: |
graph_name.legend option_list |
Note: the syntax of the legend proc has changed considerably from version 3.1 of EViews. While not documented here, the EViews 3 options are still (for the most part) supported. However, we do not recommend using the old options as future support is not guaranteed.
Options
columns(arg) Columns for legend: “auto” (automatically choose num- (default=“auto”) ber of columns), int (put legend in specified number of
columns).
display/–display |
Display/do not display the legend. |
|
|
inbox/–inbox |
Put legend in box/remove box around legend. |

legend—333
position(arg)
font([face], [pt], [+/- b], [+/- i], [+/- u], [+/- s])
textcolor(arg)
fillcolor(arg)
framecolor(arg)
Position for legend: “left” or ”l” (place legend on left side of graph), “right” or “r” (place legend on right side of graph), “botleft” or “bl” (place left-justified legend below graph), “botcenter” or “bc” (place centered legend below graph), “botright” or “br” (place right-justi- fied legend below graph), “(h, v)” (the first number h specifies the number of virtual inches to offset to the right from the origin. The second number v specifies the virtual inch offset below the origin. The origin is the upper left hand corner of the graph).
Set characteristics of legend font. The font name (face), size (pt), and characteristics are all optional. face should be a valid font name, enclosed in double quotes. pt. should be the font size in points. The remaining options specify whether to turn on/off boldface (b), italic (i), underline (u), and strikeout (s) styles.
Sets the color of the legend text. arg may be one of the predefined color keywords, or it may be made up of n1, n2, n3, a set of three integers from 0 to 255, representing the RGB values of the color. For a description of the available color keywords (“blue”, “red”, “green”, “black”, “white”, “purple”, “orange”, “yellow”, “gray”, “ltgray”), see setfillcolor (p. 453).
Sets the background fill color of the legend box. arg may be one of the predefined color keywords, or it may be made up of n1, n2, n3, a set of three integers from 0 to 255, representing the RGB values of the color. For a description of the available color keywords (“blue”, “red”, “green”, “black”, “white”, “purple”, “orange”, “yellow”, “gray”, “ltgray”), see setfillcolor
(p. 453).
Sets the color of the legend box frame. arg may be one of the predefined color keywords, or it may be made up of n1, n2, n3, a set of three integers from 0 to 255, representing the RGB values of the color. For a description of the available color keywords (“blue”, “red”, “green”, “black”, “white”, “purple”, “orange”, “yellow”, “gray”, “ltgray”), see setfillcolor (p. 453).
334—Appendix B. Command Reference
The options which support the “-” may be proceeded by a “+” or “-” indicating whether to turn on or off the option. The “+” is optional.
The default settings are taken from the global defaults.
Examples
mygra1.legend display position(l) inbox
places the legend of MYGRA1 in a box to the left of the graph.
mygra1.legend position(.2,.2) -inbox
places the legend of MYGRA1 within the graph, indented slightly from the upper left corner with no box surrounding the legend text.
mygra1.legend font("Times", 12, b, i) textcolor(red) fillcolor(blue) framecolor(blue)
sets the legend font to red “Times” 12pt bold italic, and changes both the legend fill and frame colors to blue.

line
Command || Coef View | Graph Command | Group View | Matrix View | Rowvector View | Series View | Sym View | Vector View
Display a line graph of object, or change existing graph object type to line plot.
The line graph view of a group plots all series in the group in a graph. The line graph view of a matrix plots each column in the matrix in a graph.

|
template may be a predefined template keyword |
