6 plptex3 - Write text inside the viewport of a 3D plot
7
9 plptex3(wx, wy, wz, dx, dy, dz, sx, sy, sz, just, text)
10
12 Writes text at a specified position and inclination and with a speci‐
13 fied shear within the viewport. Text is clipped at the viewport bound‐
14 aries. The reference point of a string lies along a line passing
15 through the string at half the height of a capital letter. The posi‐
16 tion of the reference point along this line is determined by just, and
17 the reference point is placed at world coordinates (wx, wy, wz) within
18 the viewport. The inclination and shear of the string is specified in
19 terms of differences of world coordinates making it easy to write text
20 parallel to a line in a graph.
21
22 Redacted form: plptex3(x, y, z, dx, dy, dz, sx, sy, sz, just, text)
23
24 This function is used in example 28.
25
27 wx (PLFLT(3plplot), input)
28 x world coordinate of reference point of string.
29
30 wy (PLFLT(3plplot), input)
31 y world coordinate of reference point of string.
32
33 wz (PLFLT(3plplot), input)
34 z world coordinate of reference point of string.
35
36 dx (PLFLT(3plplot), input)
37 Together with dy and dz , this specifies the inclination of the
38 string. The baseline of the string is parallel to a line join‐
39 ing (x, y, z) to (x+dx, y+dy, z+dz) .
40
41 dy (PLFLT(3plplot), input)
42 Together with dx and dz, this specifies the inclination of the
43 string.
44
45 dz (PLFLT(3plplot), input)
46 Together with dx and dy, this specifies the inclination of the
47 string.
48
49 sx (PLFLT(3plplot), input)
50 Together with sy and sz , this specifies the shear of the
51 string. The string is sheared so that the characters are verti‐
52 cally parallel to a line joining (x, y, z) to (x+sx, y+sy,
53 z+sz) . If sx = sy = sz = 0.) then the text is not sheared.
54
55 sy (PLFLT(3plplot), input)
56 Together with sx and sz, this specifies shear of the string.
57
58 sz (PLFLT(3plplot), input)
59 Together with sx and sy, this specifies shear of the string.
60
61 just (PLFLT(3plplot), input)
62 Specifies the position of the string relative to its reference
63 point. If just=0. , the reference point is at the left and if
64 just=1. , it is at the right of the string. Other values of
65 just give intermediate justifications.
66
67 text (PLCHAR_VECTOR(3plplot), input)
68 A UTF-8 character string to be written out.
