# Numbers and strings in komplot

#### Introduction

After a call to frame one can plot strings and numbers in various formats with the routines described in this section. XP, YP, HEIGHT, ANGLE are common parameters.
XP, YP (real)
coordinates of the lower-left point of the first character, units defined by sign(HEIGHT).
XP = 999.0 : actual XP is the X-coordinate of the lower right point of the last character plotted by the previous string or number routine.
YP = 999.0 : actual YP is the Y-coordinate of the lower right point of the last character plotted by the previous string or number routine. See remarks below.
HEIGHT (real)
abs(HEIGHT) is the character height in cm. ( >= 0.1)
HEIGHT>0.0 : XP, YP expressed in data units as defined by frame
HEIGHT<0.0 : XP, YP expressed in cm. relative to the origin of the axis system.
ANGLE (real)
angle in degrees with the X-axis (from left to right).

Space for a number-sign is reserved before each number. Only a minus-sign is plotted. Numbers not fitting in the specified format are represented by **.

subroutine GSTRNG(XP, YP, HEIGHT, ANGLE, STRNG)
Plot string STRNG, with maximal 48 characters.
subroutine GREAL(XP, YP, HEIGHT, ANGLE, IFRMT, REAL)
Plot real variable REAL with fixed point format specified by IFRMT=100*N+M, where: N is the number of digits before the decimal point and M is the number of digits after the decimal point.
subroutine GFLOAT(XP, YP, HEIGHT, ANGLE, IFRMT, FLOAT)
Plot float variable FLOAT in floating point format defined by IFRMT=100*N+M, where N is the number of digits of mantisse (0.1<=abs(mantisse)< 1.0) and M is the power of 10
subroutine GINTGR(XP, YP, HEIGHT, ANGLE, IFRMT, INTGR)
Plot integer INTGR with maximal IFRMT positions.

#### Sequence of strings and or numbers, subscripts and superscripts

• The option XP = 999.0 is useful to plot a sequence of numbers and/or strings ('elements') on a line parallel to the X-axis (ANGLE =0.0) with some value of YP. Then you only have to compute the XP for the routine plotting the first 'elements, following elements have XP = 999.0. Similar for a sequence parallel to the Y-axis and YP = 999.0.
• By varying YP and HEIGHT for a sequence of numbers and/or strings parallel to the X-axis, subscripts and superscripts can be plotted.
