Introduction

Generates a multi-value scatter plot file, where each data point is annotated by up to 10 fields centered on this point.

How to use

Individual character size, offsets, angle and decimal places must be specified interactively for each field.

The input file should contain just one entry for each location. If it contains more than one, then there will be multiple plots at that location.

Files, Fields and Parameters

Input Files

Name	Description	I/O Status	Required	Type
IN	Input data file. This must contain X and Y fields and at least one value field.	Input	Yes	Undefined
PROTO	Plot prototype file. Must contain the fields X, Y, S1, S2 and CODE (numeric, explicit) and XMIN, XMAX, YMIN, YMAX, XSCALE, YSCALE (numeric, implicit). If these last 6 values set in PROTO , then corresponding parameters need not be set.	Input	Yes	Plot Prototype

Output Files

Name	I/O Status	Required	Type	Description
PLOT	Output	Yes	Plot	Output plot file.

Fields

Name	Description	Source	Required	Type	Default
X	Field to be plotted along X axis.	IN	Yes	Numeric	Undefined
Y	Field to be plotted along Y axis.	IN	Yes	Numeric	Undefined
SYMCODE	The SYMCODE value will control the symbol used on each point. If used, it will override the SYMBOL parameter.	IN	No	Numeric	Undefined

Parameters

Name	Description	Required	Default	Range	Values
ANGLE	Angle for symbol plotting in degrees from the X axis.(0)	No	0	Undefined	Undefined
SYMBOL	Plotted symbol at each point. Default (92). Point symbol number 91 : Circle (o) 92 : Cross (+) 93 : Cross (x) 94 : Triangle 95 : Box 96 : Diamond 97 : Star 98 : Pie Segment. Can also be from the standard symbol set (codes 201 - 267) ( )	No	92	91,267	Undefined
SYMSIZE	Symbol size in millimetres (3). Set to 0 for no symbol.	No	3	Undefined	Undefined
ASPRATIO	Aspect ratio, width / ht. for chars (0.9).	No	0.9	Undefined	Undefined
	Colour [as 'pen' number] for plot (1).	No	1	Undefined	Undefined
APPEND	Plot append flag. If set to 1 then the new plot will be appended to the PLOT file, if it exists and is a valid plot file (0).	No	0	0,1	0,1
XMIN	Minimum value of X for plot. None of XMIN, XMAX, YMIN, YMAX, XSCALE, YSCALE need be set if this information is already in the prototype.	No	Undefined	Undefined	Undefined
XMAX	Maximum value of X for plot.	No	Undefined	Undefined	Undefined
YMIN	Minimum value of Y for plot.	No	Undefined	Undefined	Undefined
YMAX	Maximum value of Y for plot.	No	Undefined	Undefined	Undefined
XSCALE	X scale in user data units per millimetre.	No	Undefined	Undefined	Undefined
YSCALE	Y scale in user data units per millimetre.	No	Undefined	Undefined	Undefined

Notes

The user is requested to enter the following information for each field to be plotted:

Field Name,
Character Size,
X Offset,
Y Offset,
Angle,
Number of Decimal Places.

Up to 10 fields can be specified terminating with a blank line or a comma in column 1. The data for each field must be specified on a single line separating data items with commas. When data entry is terminated the user is prompted to enter 0 to start plotting, 1 to add more fields or 2 to start data entry again.

Example

!PLOTVA

&IN(SEDREG),&PROTO(PLOTPROT),&PLOT(SEDREGPL),

@SYMBOL=93,@SYMSIZE=5,@=5,

@XMIN=5000,@XMAX=10000,@YMIN=25000,@YMAX=30000

INTERACTIVE ENTRY OF PLOTTING DATA
==================================
Please enter the following information :
Field Name , Character Size , X Offset , Y Offset ,
Angle , No.Decimals
Separate data items with a comma, one field per line
Terminate data entry with a blank line or with a comma
in column 1

You may enter up to a maximum of 10 fields

DATA   >Cu,4,-15,10,0,2
DATA   >Pb,4,5,10,0,2
DATA   >Zn,4,-5,-10,0,2
DATA   ><return>

DATA SUMMARY
------------

Field Name	Size	Xoffset	Yoffset	Angle	Decimals	Type
Cu	4	-15	10	0	2	N
Pb	4	5	10	0	2	N
Zn	4	-5	-10	0	2	N

Is data entry correct ?
    0 - to start plotting
    1 - to add more fields
    2 - to start again
    ! - to abandon the process

Error and Warning Messages

Message	Description	Solution
>>> CANNOT APPEND TO NON-EXISTENT OUTPUT FILE. >>> A NEW OUTPUT FILE WILL BE CREATED	The @APPEND parameter has been set to 1, but the specified plot file does not exist. A new file will be created to contain the new plot being produced.

>>> ERROR - CANNOT APPEND TO PLOT FILE AS IT DOES >>> NOT CONTAIN ALL THE REQUIRED FIELDS. >>> THE PLOT FILE WILL BE OVERWRITTEN.	The @APPEND parameter has been set to 1, the specified plot file exists but is invalid. The existing plot file will be overwritten by the new plot being produced.

>>> FATAL ERROR, BAD SCALE/RANGE COMBINATION(S) <<< >>> XMIN, XMAX = nnnnnnnnnn.nn nnnnnnnnn.nn >>> YMIN, YMAX = nnnnnnnnnn.nn nnnnnnnnn.nn >>> XSCALE, YSCALE = nnnnnnnnnn.nn nnnnnnnnn.nn	Either insufficient scale information had been entered (at least two of XMIN, XMAX, XSCALE or Y equivalents must be entered either from the prototype of from parameters) or the combination given of XMIN, XMAX, and XSCALE (or their Y equivalents) was impossible. Often caused by entering a null plot prototype and no parameters. Fatal; the process is exited.

>>> INSUFFICIENT DATA. RE_ENTER THE LINE. <<<	Insufficient annotation information has been entered. The user is prompted to re-enter the line of data.

>>> ERROR IN FIELD NAME. RE-ENTER THE LINE. <<<	An error has been detected in the field name entry. The user is prompted to re-enter the line of data.

>>> FIELD ffffffff DOES NOT EXIST. RE-ENTER THE LINE. <<<	The annotation field entered does not exist in the input data file. The user is prompted to re-enter the line of data.

>>> ERROR - REPLY MUST BE 0, 1, 2 or !	The response to the question 'Is data entry correct?' must be 0, 1, 2 or !.
