scalar

434—Appendix B. Command Reference

Note: the syntax of scale has changed considerably from version 4.1 of EViews (see, in particular axis (p. 217)). While not documented here, the previous options are still (for the most part) supported. However, we do not recommend using the old options as future support is not guaranteed.

Options

The options list may include any of the following options:

Data scaling options

Axes scaling options

overlap / -over- [Overlap / Do not overlap] scales on dual scale graphs. lap

invert / -invert [Invert / do not invert] scale.

Note that the default settings are taken from the global defaults.

Examples

To set the right scale to logarithmic with manual range, you can enter:

graph1.scale(right) log range(10, 30)

Alternatively,

scat—435

graph1.scale -invert range(minmax)

draws duplicate inverted scales on the left and right axes which are defined to match the data range.

Display scatterplot graph of object, or change existing graph object type to scatterplot (if possible).

By default, the first series or column of data will be located along the horizontal axis, and the remaining data on the vertical axis. You may optionally choose to plot the data in pairs, where the first two series or columns are plotted against each other, the second two series or columns are plotted against each other, and so forth.

Syntax

If used as a command, follow the keyword by a list of series and group objects, or by a matrix object. There must be at least two series or columns in the data to be graphed.

Scatterplots are simply XY plots (see xy (p. 556)) with symbols turned on, and lines turned off (see setelem (p. 449)).

Options

Template and printing options

o= template Use appearance options from the specified template. template may be a predefined template keyword (‘default” - current global defaults, “classic”, “modern”, “reverse”, “midnight”, “spartan”, “monochrome”) or a graph in the workfile.

t=graph_name Use appearance options and copy text and shading from

The options which support the “-” may be proceeded by a “+” or “-” indicating whether to turn on or off the option. The “+” is optional.

Note that use of the template option will override the symbol setting.

Scale options

mDisplay XY plots in multiple graphs (will override the “s” option). Not for use with an existing graph object.

Panel options

The following options apply when graphing panel structured data.

scat—437

from global settion), “combine” or “c” (combine each cross-section in

Examples

scat unemp inf want

produces an UNTITLED graph object containing a scatter plot, with UNEMP on the horizontal and INF and WANT on the vertical axis.

group med age height weight

med.scat(t=scat2)

produces a scatter plot view of the group object MED, using the graph object SCAT2 as a template.

group pairs age height weight length

pairs.scat(b)

produces a scatter plot view with AGE plotted against HEIGHT, and WEIGHT plotted against LENGTH.

If there is an existing graph GRAPH01, the expression:

graph01.scat(b)

changes its type to a scatterplot with data plotted in pairs (if possible), with the remaining XY graph settings at their default values.
