dbopen |
Command |
|
|
Open an existing database. |
|
Syntax |
|
Command: |
dbopen(options) [path\]db_name [as shorthand_name] |
Follow the dbopen keyword with the name of a database. You should include a path name to open a database not in the default path. The opened database will become the default database.
You may use the “as” keyword to provide an optional shorthand_name or a short text label which is used to refer to the open database in commands and programs. If you leave this field blank, a default shorthand_name will be assigned automatically. See “Database Shorthands” in the User’s Guide for additional discussion.
By default, EViews will use the extension of the database file to determine type. For example, files with the extension “.EDB” will be opened as an EViews database, while files with the extension “.IN7” will be opened as a GiveWin database. You may use options to specify an explicit type.
Options
type=arg, t=arg Specify the database type: AREMOS-TSD (“a”, “aremos”, “tsd”), DRIBase (“b”, “dribase”), EViews (“e”, “evdb”), FAME (“f”, “fame”), GiveWin/PcGive (“g”, “give”), Haver Analytics (“h”, “haver”), Rats Portable/ Troll (“l”, “trl”), RATS 4.x (“r”, “rats”), TSP portable (“t”, “tsp”), EcoWin (“ecowin”).

Examples
dbopen c:\data\us1
opens a database named US1 in the C:\DATA directory. The command:
dbopen us1
opens a database in the default path. If the specified database does not exist, EViews will issue an error message. You should use db or dbcreate to create a new database.

draw |
Graph Proc |
|
|
Place horizontal or vertical lines and shaded areas on the graph.
Syntax
Graph Proc: |
graph_name.draw(draw_type, axis_id [,options]) position1 |
|
[position2] |
where draw_type may be one of the following:
line / l |
A line |
|
|
shade |
A shaded area |
Note that the “dashline” option has been removed (though it is supported for backward compatibility). You should use the “pattern” option to specify whether the line is solid or patterned.
88—Chapter 6. EViews 5.1 Command Reference Update Summary
axis_id may take the values:
left / l |
Draw a horizontal line or shade using the left axis to |
|
define the drawing position |
|
|
right / r |
Draw a horizontal line or shade using the right axis to |
|
define the drawing position |
|
|
bottom / b |
Draw a vertical line or shade using the bottom axis to |
|
define the drawing position |
|
|
If drawing a line, the drawing position is taken from position1. If drawing a shaded area, you must provide a position1 and position2 to define the boundaries of the shaded region.
Line/Shade Options
The following options may be provided to change the characteristics of the specified line or shade. Any unspecified options will use the default text settings of the graph.
color(arg) |
Specifies the color of the line or shade. the argument |
|
may be made up of n1, n2, and n3, a set of three inte- |
|
gers from 0 to 255, representing the RGB values of the |
|
line or shade, or it may be one of the predefined color |
|
keywords (“blue”, “red”, “green”, “black”, “white”, |
|
“purple”, “orange”, “yellow”, “gray”, “ltgray”). For a |
|
full description of the keywords, see setfillcolor. |
|
The default is black for lines and gray for shades. RGB |
|
values may be examined by calling up the color palette |
|
in the Graph Options dialog. |
|
|
pattern(index) |
Sets the line pattern to the type specified by index. |
|
index can be an integer from 1 to 12 or one of the |
|
matching keywords (“solid”, “dash1” through |
|
“dash10”, “none”). See setelem (p. 126) for a descrip- |
|
tion of the available patterns. The “none” keyword |
|
turns on solid lines. |
|
|
width(n1) |
Specify the width, where n1 is the line width in points |
|
(used only if object_type is “line” or “dashline”). The |
|
default is 0.5 points. |
|
|
Examples
graph1.draw(line, left, rgb(0,0,127)) 5.25
draws a horizontal blue line at the value “5.25” as measured on the left axis while:
EViews 5.1 Command Reference Update Summary—89
graph1.draw(shade, right) 7.1 9.7
draws a shaded horizontal region bounded by the right axis values “7.1” and “9.7”. You may also draw vertical regions by using the “bottom” axis_id:
graph1.draw(shade, bottom) 1980:1 1990:2
draws a shaded vertical region bounded by the dates “1980:1” and “1990:2”.
graph1.draw(line, bottom, pattern(dash1)) 1985:1
draws a vertical dashed line at “1985:1”.

drawdefault |
Graph Proc |
|
|
Change default settings for lines and shaded areas in the graph.
This command specifies changes in the default settings which will be applied to line and shade objects added subsequently to the graph. If you include the “existing” option, all of the drawing default settings will also be applied to existing line and shade objects in the graph.
Syntax
Graph Proc: |
graph_name.drawdefault draw_options |
where draw_options may include one or more of the following:
linecolor(arg) |
Sets the default color for lines. The arg value may set by |
|
using one of the color keywords (e.g., “blue”), or by |
|
using the RGB values (e.g., “@RGB(255, 255, 0)”). For |
|
a description of the available color keywords (“blue”, |
|
“red”, “green”, “black”, “white”, “purple”, “orange”, |
|
“yellow”, “gray”, “ltgray”). For a full description of the |
|
keywords, see setfillcolor. |
|
|
90—Chapter 6. EViews 5.1 Command Reference Update Summary
shadecolor(arg) |
Sets the default color for shades. 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, represent- |
|
ing 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. |
|
|
width(n1) |
Specify the width, where n1 is the line width in points |
|
(used only if object_type is “line” or “dashline”). The |
|
default is 0.5 points. |
|
|
pattern(index) |
Sets the default line pattern to the type specified by |
|
index. index can be an integer from 1 to 12 or one of |
|
the matching keywords (“solid”, “dash1” through |
|
“dash10”, “none”). See setelem (p. 126) for a descrip- |
|
tion of the available patterns. The “none” keyword |
|
turns on solid lines. |
|
|
existing |
Apply the default settings to all existing line/shade |
|
objects in the graph. |
|
|
Examples
graph1.drawdefault linecolor(blue) width(.25) existing
changes the default setting for new line/shade objects. New lines added to the graph will now be drawn in blue, with a width of 0.25 points. In addition, all existing line and shade objects will be updated with the graph default settings. Note that in addition to the line color and width settings specified in the command, the existing default line pattern and shade colors will be applied to the line and shade objects in graph.
graph1.drawdefault existing
updates all line and shade objects in the graph with the currently specified default draw object settings.
