Plot a glyph at the specified points. (This function is largely superseded by plstring which gives access to many[!] more glyphs.) code=-1 means try to just draw a point. Right now it's just a move and a draw at the same place. Not ideal, since a sufficiently intelligent output device may optimize it away, or there may be faster ways of doing it. This is OK for now, though, and offers a 4X speedup over drawing a Hershey font "point" (which is actually diamond shaped and and therefore takes 4 strokes to draw). If 0 < code < 32, then a useful (but small subset) of Hershey symbols is plotted. If 32 <= code <= 127 the corresponding printable ASCII character is plotted.
| n | Number of points in x and y arrays. |
| x | Pointer to an array with X coordinates of points. |

Plot a glyph at the specified 3D points. (This function is largely superseded by plstring3 which gives access to many[!] more glyphs.) Set up the call to this function similar to what is done for plline3. code=-1 means try to just draw a point. Right now it's just a move and a draw at the same place.

| void c_plstring | ( | PLINT | n, |

| PLCHAR_VECTOR | string | ||
| ) |
Plot a glyph at the specified points. (This function largely supersedes plpoin and plsym because many[!] more glyphs are accessible with plstring.) The glyph is specified with a PLplot user string. Note that the user string is not actually limited to one glyph so it is possible (but not normally useful) to plot more than one glyph at the specified points with this function. As with plmtex and plptex, the user string can contain FCI escapes to determine the font, UTF-8 code to determine the glyph or else PLplot escapes for Hershey or unicode text to determine the glyph.

| ) |
Calculate scale of font size and scale of magnitude of vertical offset associated with superscripts and subscripts. Notes on arguments: ifupper must be either TRUE or FALSE on every call to plP_script_scale. The contents of the location pointed to by the level pointer must be zero on the first call to plP_script_scale, but not modified externally from then on. The contents of the locations pointed to by all other pointer arguments are initialized internally, and should not be modified externally.
| ifupper | Value which is TRUE if superscripting, i.e., if incrementing the previous level, and FALSE if subscripting, i.e., decrementing the previous level. |
| level | Pointer to a location which contains the value of the superscript/subscript level. That value is 0, +-1, +-2, etc., for no superscript/subscript, the first level of superscript/subscript, the second level of superscript/subscript, etc. Before the call the value is the old level, and after the call the value will be incremented (ifupper TRUE) or decremented (ifupper FALSE) from the previous value. |
| old_scale | A pointer to a location that contains after the call the old font size scale value. |
| scale | A pointer to a location that contains after the call the font size scale value. This value is 0.75^{|level|} where |level| is the magnitude of the value of the superscript/subscript level after the call. |
| old_offset | A pointer to a location that contains after the call the old value of the magnitude of the superscript/subscript offset. |
| offset | A pointer to a location that contains after the call the value of the magnitude of the superscript/subscript offset which is zero for |level|=0 and sum_{i=1}^{i=|level|} 0.75^{i-1}, otherwise. |
