Plot Hours of Sleep Versus Age
Problem Statement:
The first data point is already graphed. A three-year-old gets 12 hours of sleep, a nine-year-old gets 9 hours of sleep, a thirteen-year-old gets 8 hours of sleep, and an eighteen-year-old gets 6 hours of sleep. Graph the data points for hours of sleep versus age.
```/* Code generated by RoboBlockly v2.0 */
#include <chplot.h>
CPlot plot;

plot.label(PLOT_AXIS_X, "age");
plot.label(PLOT_AXIS_Y, "hours");
plot.point(1, 18);
plot.point(3, 12);
plot.point(9, 9);
plot.point(13, 8);
plot.point(18, 6);

plot.axisRange(PLOT_AXIS_XY, -12, 24);
plot.ticsRange(PLOT_AXIS_XY, 6);
plot.sizeRatio(1);
