Examples of org.jrobin.graph.RrdGraphDef

org.jrobin.graph.RrdGraphDef
Class which should be used to define new JRobin graph. Once constructed and populated with data object of this class should be passed to the constructor of the {@link RrdGraph} class whichwill actually create the graph.
The text printed below the actual graph can be formated by appending special escaped characters at the end of a text. When ever such a character occurs, all pending text is pushed onto the graph according to the character specified.
Valid markers are: \j for justified, \l for left aligned, \r for right aligned and \c for centered.
Normally there are two space characters inserted between every two items printed into the graph. The space following a string can be suppressed by putting a \g at the end of the string. The \g also squashes any space inside the string if it is at the very end of the string. This can be used in connection with %s to suppress empty unit strings.
A special case is COMMENT:\s this inserts some additional vertical space before placing the next row of legends.
When text has to be formated without special instructions from your side, RRDTool will automatically justify the text as soon as one string goes over the right edge. If you want to prevent the justification without forcing a newline, you can use the special tag \J at the end of the string to disable the auto justification.
