PLOT TEXT ☆

PLOT TEXT ,AT x,y : s$
draws a label consisting of s$ at the point (x,y) ,where s$ is a string expression, and x,y are numeric expressions.
Examples
PLOT TEXT ,AT 0, 0.2: "BASIC"
PLOT TEXT ,AT x, 0: STR$(x)


PLOT TEXT ,AT x,y ,USING Format$ : exp1, exp2, ...
draws a label of which literals are those of exp1, exp2, ...
Format$ is a string expression of which value is a format string.
Both numerical expressions and string expressions can be written for exp1, exp2, ....
Example
PLOT TEXT ,AT x,y ,USING "#.### #.###":a,b

SET TEXT HEIGHT a
specifies the text height on the problem coordinate, where a is a numeric expression.

SET TEXT COLOR n
specifies the text foreground color, where n is a numeric expression.
The default text color is 1.

SET TEXT JUSTIFY h$, v$
designates the base point for texts.
h$ is one of "LEFT" , "CENTER" , or "RIGHT".
v$ is one of "TOP","CAP","HALF","BASE",or "BOTTOM"
Example
SET TEXT JUSTIFY "right" , "top"
The default text justify is "LEFT","BOTTOM".

SET TEXT ANGLE a
designates the angle of the text, where a is a numeric expression.
The unit of angle depends on OPTION ANGLE.

ASK TEXT HEIGHT Numeric_Variable
assigns the text height on the problem coordinate

ASK TEXT COLOR numeric_Variable
assigns the current text color

ASK TEXT JUSTIFY String_Variable1，String_Variable2
assigns the current text justification.

ASK TEXT ANGLE numeric_variable
assigns the current text angle.

Incompatibility with the standard
(1) When no transformation is applied, text figures and text angles are managed with respect to the physical coordinates.
(2) The default text height is determined by the font menu of the graphics window.
(3) If Graphics object is a metafile, PLOT TEXT always draw texts with respect to the physical coordinates.

Original Enhancement

PLOT LABEL ,AT x,y : String_Expression
PLOT LABEL ,AT x,y ,USING Format_String : expression, expression , …, expression
draw the label.
Only the base point is transformed.
The shape, size and direction are not transformed.

SET TEXT FONT FontName$
specifies the text font name.

SET TEXT FONT FontName$ ，size
specifies the text font name and the size in points.
If the first parameter is null, only the size is changed.
If size is zero, The former size is preserved.
This has no compatibility with SET TEXT HEIGHT, so do not use this together with SET TEXT HEIGHT.
This suits the circumstances where PLOT LABEL statements are used.
Examples.
SET TEXT FONT "Courier New",12
SET TEXT FONT "Times New Roman Italic" ,0
SET TEXT FONT "",9


SET TEXT BACKGROUND "OPAQUE"
Background of text is to be filled with the color of color index 0.
SET TEXT BACKGROUND "TRANSPARENT"
Background of text is not to be painted.

ASK TEXT WIDTH(s$) n
assigns the width of string expression s$ in the problem coordinates to a numeric variable n.

ASK TEXT BACKGROUND s$
substitute s$ with the current text background.

ASK TEXT FONT s$, n
substitute s$ and n with the current text font name and size in points.

Obsolete original enhancement

PLOT LETTERS ,AT x,y : String_Expression
PLOT LETTERS ,AT x,y ,USING Format_String : expression, expression , …, expression
draw the label.
The shape is preserved.
Only the base point and the size and direction are transformed.
