**Specifying X-Axis Data**

Bar graphs automatically generate *x*-axis values and label the *x*-axis tick lines. You can specify a vector of *x* values (or *y* values in the case of horizontal bar graphs) to label the axes.

For example, given temperature data,

obtained from samples taken every five days during a thirty-five day period,

you can display a bar graph showing temperature measured along the *y*-axis and days along the *x*-axis using

These statements add labels to the *x*- and *y*-axis.

**Setting Y-Axis Limits**

By default, the *y*-axis range is from 0 to 30. To focus on the temperature range from 15 to 30, change the *y*-axis limits.
