/**
* Configures x-axis grid and labels. The x-axis label is quite complex to configure.
* So if you don't have very special needs, you can rely on the autoconfiguration to
* get this right.
* <p/>
* Otherwise, you have to configure three elements making up the x-axis labels
* and grid. The base grid, the major grid and the labels.
* The configuration is based on the idea that you first specify a well
* known amount of time and then say how many times
* it has to pass between each minor/major grid line or label. For the label
* you have to define two additional items: The precision of the label
* in seconds and the format used to generate the text
* of the label.
* <p/>
* For example, if you wanted a graph with a base grid every 10 minutes and a major
* one every hour, with labels every hour you would use the following
* x-axis definition.
* <p/>
* <pre>
* setTimeAxis(RrdGraphConstants.MINUTE, 10,
* RrdGraphConstants.HOUR, 1,
* RrdGraphConstants.HOUR, 1,
* 0, "%H:%M")
* </pre>
* <p/>
* The precision in this example is 0 because the %X format is exact.
* If the label was the name of the day, we would have had a precision
* of 24 hours, because when you say something like 'Monday' you mean
* the whole day and not Monday morning 00:00. Thus the label should
* be positioned at noon. By defining a precision of 24 hours or
* rather 86400 seconds, you make sure that this happens.
*
* @param minorUnit Minor grid unit. Minor grid, major grid and label units
