# 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;
