**plptex3** — Write text inside the viewport of a 3D plot

## Synopsis

**plptex3**(*wx*, *wy*, *wz*, *dx*, *dy*, *dz*, *sx*, *sy*, *sz*, *just*, *text*)

## Description

Writes text at a specified position and inclination and with a specified shear within the viewport. Text is clipped at the viewport boundaries. The reference point of a string lies along a line passing through the string at half the height of a capital letter. The position of the reference point along this line is determined by *just*, and the reference point is placed at world coordinates (*wx*, *wy*, *wz*) within the viewport. The inclination and shear of the string is specified in terms of differences of world coordinates making it easy to write text parallel to a line in a graph.

Redacted form: **plptex3(x, y, z, dx, dy, dz, sx, sy, sz, just, text)**

This function is used in example 28.

## Arguments

*wx*(PLFLT, input)- x world coordinate of reference point of string.
*wy*(PLFLT, input)- y world coordinate of reference point of string.
*wz*(PLFLT, input)- z world coordinate of reference point of string.
*dx*(PLFLT, input)- Together with
*dy*and*dz*, this specifies the inclination of the string. The baseline of the string is parallel to a line joining (*x*,*y*,*z*) to (*x*+*dx*,*y*+*dy*,*z*+*dz*) . *dy*(PLFLT, input)- Together with
*dx*and*dz*, this specifies the inclination of the string. *dz*(PLFLT, input)- Together with
*dx*and*dy*, this specifies the inclination of the string. *sx*(PLFLT, input)- Together with
*sy*and*sz*, this specifies the shear of the string. The string is sheared so that the characters are vertically parallel to a line joining (*x*,*y*,*z*) to (*x*+*sx*,*y*+*sy*,*z*+*sz*) . If*sx*=*sy*=*sz*= 0.) then the text is not sheared. *sy*(PLFLT, input)- Together with
*sx*and*sz*, this specifies shear of the string. *sz*(PLFLT, input)- Together with
*sx*and*sy*, this specifies shear of the string. *just*(PLFLT, input)- Specifies the position of the string relative to its reference point. If
*just*=0. , the reference point is at the left and if*just*=1. , it is at the right of the string. Other values of*just*give intermediate justifications. *text*(const char *, input)- The string to be written out.
