## Title, key title, and lable

### Title

In order to make a title for a plot,
gnuplot> set title "Exponential Function"

gnuplot> plot exp(x)

gnuplot> plot exp(x)

gnuplot> set title font "Helvetica,14"

gnuplot> plot exp(x)

The value, 14, is the size of the font.
gnuplot> plot exp(x)

### Key Title

If you have several functions to plot and put a title for the entire keys, use "key title." Let's try some example. There are two functions, sin(x) and cos(x). Then, the key title can be "Trigonometric Functions."
gnuplot> set key title "Trigonometric Functions"

gnuplot> plot sin(x), cos(x)

gnuplot> plot sin(x), cos(x)

### Lable

For labels of each axis, you have the command as follows:
gnuplot> set xlabel "Time"

gnuplot> set ylabel "Growth"

gnuplot> plot exp(x)

gnuplot> set ylabel "Growth"

gnuplot> plot exp(x)

### Arrow

An arrow can be displayed in the graph to indicate a place to note. The values of coordinate must be based on the plot ranges as default. Let's give an example:
gnuplot> set label 'Minimum point' at 0.5,-0.35

gnuplot> set arrow from 1.5,-0.3 to 4,-0.22

gnuplot> plot sin(x)/x

gnuplot> set arrow from 1.5,-0.3 to 4,-0.22

gnuplot> plot sin(x)/x
