11.135 Sample ‘text’ ¶

Example of text possibilities.

MGL code:

call 'prepare1d'
subplot 2 2 0 ''
text 0 1 'Text can be in ASCII and in Unicode'
text 0 0.6 'It can be \wire{wire}, \big{big} or #r{colored}'
text 0 0.2 'One can change style in string: \b{bold}, \i{italic, \b{both}}'
text 0 -0.2 'Easy to \a{overline} or \u{underline}'
text 0 -0.6 'Easy to change indexes ^{up} _{down} @{center}'
text 0 -1 'It parse TeX: \int \alpha \cdot \
\sqrt3{sin(\pi x)^2 + \gamma_{i_k}} dx'
subplot 2 2 1 ''
 text 0 0.5 '\sqrt{\frac{\alpha^{\gamma^2}+\overset 1{\big\infty}}{\sqrt3{2+b}}}' '@' -2
text 0 -0.1 'More text position: \frac{a}{b}, \dfrac{a}{b}, [\stack{a}{bbb}], [\stackl{a}{bbb}], [\stackr{a}{bbb}], \sup{a}{sup}, \sub{a}{sub}'text 0 -0.5 'Text can be printed\n{}on several lines'
text 0 -0.9 'or with color gradient' 'BbcyrR'
subplot 2 2 2 '':box:plot y(:,0)
text y 'This is very very long string drawn along a curve' 'k'
text y 'Another string drawn above a curve' 'Tr'
subplot 2 2 3 '':line -1 -1 1 -1 'rA':text 0 -1 1 -1 'Horizontal'
line -1 -1 1 1 'rA':text 0 0 1 1 'At angle' '@'
line -1 -1 -1 1 'rA':text -1 0 -1 1 'Vertical'
