xstring draw strings

## Syntax

              xstring(x, y, str)
              xstring(x, y, str, angle)
              xstring(x, y, str, angle, box)

## Arguments

x,y

  real vectors or scalars, coordinates of the lower-left point of the strings.

str

  matrix of strings.

  Starting from Scilab 5.2, it is possible to write LaTeX or MathML expression.

angle

  real vector or scalar, clockwise angle in degree; default is 0.

box

  integer vector or scalar, default is 0.

## Description

If `x` is a real scalar, it's regarded as a vector with the size of `y` whose elements are set to `x`.

If `y` is a real scalar, it's regarded as a vector with the size of `x` whose elements are set to `y`.

`xstring` draws n strings at location `(x[i], y[i])` in the current graphic scale.

If `str` contain n elements, these n elements are the n drawn strings.

Otherwise, each row of the matrix stands for a line of text and row elements stand for words separated by a white space.

If `angle` is a real scalar, it's regarded as a vector of size n whose elements are set to `angle`.

`angle(i)`gives the slope in degree used for drawing the strings at location `(x[i], y[i])`.

If `box` is an integer scalar, it's regarded as a vector of size n whose elements are set to `box`.

If `box(i)` is 1 and `angle(i)` is 0, a box is drawn around the strings at location `(x[i], y[i])`.

## Examples

    plot2d([0;1],[0;1],0)
    xstring(0.5,0.5,["$\overbrace{Scilab}$" "n''est ";"pas" "$\underbrace{Matlab}$"])
    // LaTeX rendering (>= Scilab 5.2)

    //Other example
    alphabet=["a" "b" "c" "d" "e" "f" "g" ..
              "h" "i" "j" "k" "l" "m" "n" ..
              "o" "p" "q" "r" "s" "t" "u" ..
              "v" "w" "x" "y" "z"];
    clf()
    plot2d([0;1],[0;2],0)
    xstring(0.1,1.8,alphabet)     // alphabet
    xstring(0.1,1.6,alphabet,0,1) // alphabet in a box
    xstring(0.1,1.4,alphabet,20)  // angle
    set(gca(), "font_style", 1, "font_size", 1);  // use symbol fonts
    xstring(0.1,0.1,alphabet)
    xstring(0.1,0.3,alphabet)
    gce().font_size = 3;          // change the font size
    xstring(0.1,0.6,"a")    //big alpha
    gce().font_size = 24;

plot2d([0;1],[0;1],0) xstring(0.5,0.5,["$\overbrace{Scilab}$" "n''est ";"pas" "$\underbrace{Matlab}$"])
