Introduction
To create a prototype plot file with defined plot and data area shape/size, and optionally data ranges and scaling factors.
How to use
PROTOP is the first process to be used before plotting starts. It defines the prototype that will subsequently be used by plot processes. The main parts defined are the plot region (the total true size of the plot) and, within this, the data area, into which most plot processes will place plotted data. Sizes are defined in millimeters, and may be measured from existing plots, so that any in-house standard plot shape and size may be duplicated.
Within the data area, it is also possible to specify data ranges and/or scales if required. Thus a plot prototype could be set up for, for example, a series of bench plans. However, ranges and scales may be defined later, if required, during the plot process itself.
Scaling
Scales are defined separately in the X and Y directions, as data units per plotted millimeter. Thus, if the data units are meters, then an X SCALE (or Y SCALE) of 1 will give one meter per plotted millimeter, or a scale of 1:1000. An X SCALE of 2 will give 1:2000, and so on. If the data units are feet, then an X SCALE of 3.28084 will give 3.28084 feet per plotted millimeter (i.e. a scale of 1:1000).
Data Ranges and Scales
The user may define three values for X and Y defining the scale (X SCALE), and minimum and maximum data values (X MIN and X MAX). Any two out of these three must be defined, and the remaining value is then calculated. However, if all three are defined, then they must be consistent; the data range must map into the defined data area at the given scale. The process checks for this. Note that if the minimum and maximum are defined, then these are mapped into the data area, and can give rise to different scales in X and Y; to ensure the same scale in X and Y, it is better to give a data minimum or maximum and the required scale.

Notes
PLOT-FILE PROTOTYPE SET-UP
-------------------------------------
A PLOT CONSISTS OF A DEFINED PLOT AREA WITHIN WHICH IS A DEFINED DATA AREA.
DEFINE THE PLOT AREA, THE OPTIONS ARE :
1 DEFINE EXPLICITLY IN MILLIMETRES
2 HORIZONTAL A0 (1189 x 841 MM)
3 VERTICAL A0 (841 x 1189 MM)
4 HORIZONTAL A1 (841 x 594 MM)
5 VERTICAL A1 (594 x 841 MM)
6 HORIZONTAL A2 (594 x 420 MM)
7 VERTICAL A2 (420 x 594 MM)
8 HORIZONTAL A3 (420 x 297 MM)
9 VERTICAL A3 (297 x 420 MM)
10 HORIZONTAL A4 (297 x 210 MM)
11 VERTICAL A4 (210 x 297 MM)
12 HORIZONTAL QUARTO (11 x 8.5 INCHES)
13 VERTICAL QUARTO (8.5 x 11 INCHES)
14 SQUARE (250 x 250 MM)
>OPT> Enter 1-14
Option 1:
DEFINE PLOT AREA EXPLICITLY IN MILLIMETRES :
>PLOT AREA X SIZE > Enter X size in mm.
>PLOT AREA Y SIZE > Enter Y size in mm.
DEFINE DATA AREA ORIGIN POSITION, IN MILLIMETERS FROM THE BOTTOM LEFT CORNER OF THE PLOT AREA :
>DATA AREA X ORIGIN> X origin of data area.
>DATA AREA Y ORIGIN> Y origin of data area.
DEFINE DATA AREA SIZE IN MILLIMETRES : MAXIMUM POSSIBLE X VALUE IS 999.99999 MAXIMUM POSSIBLE Y VALUE IS 999.99999
>DATA AREA X SIZE > X size of data area in mm.
>DATA AREA Y SIZE > Y size of data area in mm.
DO YOU WISH TO DEFINE SCALING IN THIS PROTOTYPE Y/(N) ? If Y or y : YOU MUST DEFINE AT LEAST TWO OF THE FOLLOWING: XMIN,YMIN AND XMAX,YMAX, OR XMIN,XSCALE AND YMIN,YSCALE, OR XMAX,XSCALE AND YMAX,YSCALE, OR YOU MAY DEFINE ALL THREE, IN WHICH CASE THE VALUES MUST BE CONSISTENT ENTER SCALE AS DATA UNITS PER PLOTTED MILLIMETER :
IF YOUR DATA UNITS ARE METRES THEN A SCALE OF 1.0 WILL GIVE ONE METRE PER PLOTTED MILLIMETRE AND A SCALE OF 0.001 WILL GIVE ONE MILLIMETRE PER PLOTTED MILLIMETRE. IF YOUR DATA UNITS ARE FEET THEN A SCALE OF 3.28084 WILL GIVE 3.28084 FEET PER PLOTTED MILLIMETRE (I.E. 1000 FEET PER PLOTTED FOOT)
>X SCALE> Scale in data units/mm. <return> to ignore.
>Y SCALE> Scale in data units/mm. <return> to ignore.
PLEASE SUPPLY THE DATA RANGES IN EACH DIRECTION :
>X MIN > Minimum data value in X. <return> to ignore.
>X MAX > Maximum data value in X. <return> to ignore.
>Y MIN > Minimum data value in Y. <return> to ignore.
>Y MAX > Maximum data value in Y. <return> to ignore.
The plot prototype file description is then displayed, followed by:-
IS THIS DEFINED PLOT-FILE PROTOTYPE OK ? >CONFIRM ? > OK, ok, YES, yes, Y or y to accept; any other response to restart the prototype entry.
