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

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

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 (*x*, *y*, *z*) 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.

*x* (PLFLT, input)

x coordinate of reference point of string.

*y* (PLFLT, input)

y coordinate of reference point of string.

*z* (PLFLT, input)

z 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.
