tp_fixsc is a scaling routine intended to be used in conjunction with plotting routines. What tp_fixsc does is scale the user supplied data so that it fits on a specified axis and has 'nice' numbers for labels.

Calling sequence

tp_fixsc(x, npts, size, xs, xmin, xmax, dx) where

Parameters:
x[] the data array to be scaled
npts the number of elements in x[]
size the length into which x[] is supposed to be fitted (in inches)
xs the returned scale facter to integer space
xmin the new minimum value for the data array (a returned value)
xmax the new maximum value for the data array (a returned value)
dx the value in data units between tic marks (a returned value)

Take a set of x,y co-ordinates and plots them, with a combination of connecting lines and/or place markers. It is important to note that the arrays are arrays of doubles, and express UNIX-plot coordinates in the current pl_space().

tp_scale(TIG) may be called first to optionally re-scale the data.

The 'mark' character to be used for marking points off can be any printing ASCII character, or 001 to 005 for the special marker characters.

In addition, the value of the 'flag' variable determines the type of line to be drawn, as follows:

  • 0 Draw nothing (rather silly)
  • 1 Marks only, no connecting lines. Suggested interval=1.
  • 2 Draw connecting lines only.
  • 3 Draw line and marks

void tp_scale (  int *  idata,
int  elements,
register int  mode,
int  length,
int *  odata,
double *  min,
double *  dx
) 
 

This routine is intended to take an array of data points as input (either integer, floating, or double), and scale it to fit in a space of LENGTH units.

An output array is returned which contains the scaled information stored in 16-bit integers. The input and output arrays may overlap, as the input will never occupy more space than the output. Also output are the minimum value encountered (MIN), and a delta factor showing the increase in value each XXXX. This DX factor is rounded to 1,2,4,5,8,or 10 to produce nicer looking axes.

Parameters:
[in] idata This pointer contains the address of the input array to be scaled. Actual type of array is determined by MODE parameter.
[in] elements Number of elements in IDATA to be used.
[in] mode Specifies type of data that IDATA points to; should be one of: 'd' - double precision 'f' - float (single precision) 'i' - integer
[in] length Contains the length (in 1/1000ths of an inch) of the region in which the data is to be scaled into. Note that the actual amount of space needed may be this value rounded up to the next inch.
[out] odata This pointer contains the address of the output array, which will always be of integer type.
[out] min This pointer contains the address of the location for minimum point found to be placed in.
dx This pointer addresses the delta value of the data which corresponds to the width of EACH tick. This implies that:
  1. This is exactly the number to divide raw data by to scale it to this scale (ex: 2 graphs with one scale factor)
  2. When this value is fed to the AXIS routine, it must be multiplied by 1000.0 first (to specify increment between one INCH ticks).
The fact that this routine returns variables of type DOUBLE has important implications for FORTRAN users. These variables must be declared of type DOUBLE PRECISION to reserve enough space.

The fromheadfract and toheadfract values indicate the length of the arrowheads relative to the length of the vector to-from. A typical value is 0.1, making the head 10% of the size of the vector. The sign of the "fract" values indicates the pointing direction. Positive points towards the "to" point, negative points towards "from". Upon return, the virtual pen is left at the "to" position.
