Writing Text on the Graphics Screen. To write text on the graphics screen, enter,
for example, the following statements:
text(3.4, -0.06,'Y1')
and
text(3.4,1.4,'Y2')
The first statement tells the computer to write ‘Y1’ beginning at the coordinates x=3.4,
y=–0.06. Similarly, the second statement tells the computer to write ‘Y2’ beginning at
the coordinates x=3.4, y=1.4. [See MATLAB Program 5–2 and Figure 5–19(a).]
